Nice videos Antonio - thanks for sharing. ThumpUp

DCM powered locos are strong pullers with lots of torque which might explain how well you BR 111 pulls. Am I seeing a trend where the new can motor locos don't pull as well, regardless of their weight?

It seems like some of your tests show that at least some locos push better than they pull, at least on your track. Is that what you are seeing? Maybe it is just the fact that when they push they don't have to cross any turnouts. I don't have any double slip turnouts yet but some of my locos really hate going through my three way turnouts.

Jim

I have almost all Märklin and mostly HO, although I do have a small number of Z gauge trains!
I have models from Era I to Era VI, but I try to focus on Eras I & III. Whoops, that one got away from me. Let's just say I focus on cool trains, regardless of the particulars :-)
So many trains and so little time.

Hello Jim

Thank you for your post

You have to take into account that in my model, and in the videos, what is inside the tunnel, where the trains leave, is a 180º curve and some S curves. The tests I'm doing are the start of the train being in these conditions, the locomotive must be able to move the train and that this does not derail, which in the background is the most difficult.
At first I thought it was possible for locomotives to push wagons more efficiently than drag them, taking into account that lateral forces in curves could behave better on those in compression couplings than in expansion.
However, although there are many cases where the locomotive pushes better than it pulls, there are more cases where the pulled train is bigger than the pushed one. I attach a photo of the excel sheet where I write down the results, "arrastrar" means pull, and "empujar" means push

pull_vs_push.jpg

As for the comparison between DCM motors and "Can" type motors, for now it seems that yes, DCM and other classic märklin motors have more power. But it can not be said that this is bad, I think that the classic engines of marklin have too much power, in the next report, which is the BR 55, 37554, you will see the big difference compared to this 3155.
I'm still looking for a relationship between what is capable of moving a locomotive and some of its features, and maybe the type of engine is decisive, I have to study it.

Hello everyone, good morning

The next locomotive is the BR 55, 37554, with a weight of 370 gr, this locomotive is very smooth in its operation and is equipped with a bell motor, it also has 4 traction tyres, I expected much more but it has not been like that.

Its features are:
Weight: 370 gr
axle arrangement: D
drive axles: 4
weight-bearing axles: 4
axles with traction tyres: 2
weight/axle: 93 gr
Adhesive weight: 231 gr
Motor type: Bell shaped armature, Can motor

The test results are:
R1 pulling: 19 cars, train weight: 1452 gr
[YOUTUBE]
[/YOUTUBE]

R1 pushing: 19 cars, train weight: 1452 gr
[YOUTUBE]
[/YOUTUBE]

R2 Pulling: 19 cars, train weight: 1452 gr
[YOUTUBE]
[/YOUTUBE]

R2 Pushing: 21 cars, train weight: 1806 gr
[YOUTUBE]
[/YOUTUBE]

And now some graphics, the horizontal axis is the catalog number of the locomotives, I'm somewhat puzzled because I expected to find some pattern of behavior, and it does not seem that there is, in the graph are the locomotives with special engines (DC Can motor, Faulhaber, Bell-shaped etc) tested so far

There is a problem with your test what i see in the videos.
You have s-curves where the train set are pulling.
It makes lost of the tractive power.
DCC means Digital Command Control.

Hello Goofy and everyone,

But S-curves are not a problem, it's my layout, and it can't be any other way, also in my layout there are too many straight lines and some visible curve is fine.
Obviously these tests are subjective and the results can't be applied directly to another layout or another locomotive, but it's what I have and what I can do.
Now if one of my locomotives say the A is capable of pulling many wagons than the B, if you also have this locomotive probably the A will pull more wagons than the B, although your installation is different from mine.
Soon I will do the test of the 39567, the Kroko Insider.

I agree. You are examining how various locos run on your layout and making comparisons. All MRR layouts have compromises to make them fit into available spaces, and yours is no different.

Keep up the good work and keep posting your videos, I am finding them very interesting myself.

Yes but the s-curvers makes lost of tractive power anyway what matter of the layout looks like.
The longer train set in the s-curves the more lost of tractive power.
Because it makes locomotive work harder.
But i like your videos and you test good. ThumpUp

Hello everyone

We continue with another locomotive only 5 gr heavier than the previous one, with 375 gr we have the E 70, in blue livery, reference 3748, the Bavarian kroko. This locomotive has a curious history, it was 1996 or 1997 and in a shop in Madrid I could get a good price for the 3448, the owner told me it was delta, and I thought that later I could upgrade to 6090, so after saving a little, I bought it. When I arrived at my house and went to test it I found that it was not delta, but analog, with an electronic inverter and also could not install a normal 6090 decoder for various reasons. Anger. And back to the store, the owner did not believe it, had to call the importer of märklin in Spain and everything was clarified. I made an agreement with him and took another locomotive with me. Some time later in 1998 I saw in another store the 3748 and it was expensive, I had to save and wait for Christmas and I bought it. This locomotive the 3748 is made in collaboration with Trix, carries a DC can motor, which transmits movement to one of the bogies, carries a special 6090 decoder.

Its features are:
Weight: 375 gr
axle arrangement: B’ B’
drive axles: 2
weight-bearing axles: 4
axles with traction tyres: 2
weight/axle: 94 gr
Adhesive weight: 188 gr (2*92)
Motor type: DC Can motor + special 6090 decoder

The test results are:
R1 pulling: 12 cars, train weight: 1034 gr

Hello everyone, good morning

The next locomotive is the BR 38, 37030, this locomotive is equipped with a bell motor that is located in the boiler, this makes the weight of the locomotive concentrate in the center, on the first two drive axles, and the consequence is that the third drive axle, the last, which is under the cabin, and which carries the traction tyres, has a certain tendency to lose grip. Otherwise the locomotive has a very smooth and silent operation.

Its features are:
Weight: 378 gr
axle arrangement: 2’ C
drive axles: 2
weight-bearing axles: 3
axles with traction tyres: 1
weight/axle: 126 gr
Adhesive weight: 158 gr

More interesting information - thanks Antonio!

When your BR 38 pauses in the series of turnouts do you think that is an electrical problem or a traction problem? It reminds me a bit of the electrical problems that some of my locos have when crossing my C track turnouts.

I am finding the differences in operation of your locos quite interesting and it shows that there is more than weight and motor involved in how well a loco pulls.

Jim

It's a electrical problem, the lok goes at low speed and passing through the turnouts is a bit of a problem. Running normally goes without a hitch

Yes, there seem to be many factors influencing it, I would like to draw some conclusion from all of this. Well I've already drawn some, for example that my tracks are laid worse than I thought

I have just recently discovered that my similar problem with C trach turnouts is caused by some sliders. Some of them, even on new locos or coaches are not flat but are bent slightly upward (away from the track) in the middle. If I bend them to be perfectly flat that problem has gone away on all of the ones that I have worked on so far. I always assumed that they must be fine when they are new but I now know that is not true!

I look forward to learning more about your traction testing and what conclusions you can draw. I think that a lot of us have track that could be a bit better to run our trains on than we had thought, but as always compromises have to be made.
Regards,
Jim

Hello everyone

The next locomotive is the V 80, märklin 36080, with a weight of 380 gr, this locomotive was one of the first of the new series of locomotives "cheap", has a special decoder but with load regulation, a central motor with traction to all axles and is completely metallic, it is also very detailed, since I bought it is in the layout working. Only one defect, passing through some turnouts, the pick-up shoe lifts the bogie on which it is mounted, this produces that if the locomotive goes at low speed loses grip and contact with the track, and stops, but at normal speeds is not noticeable.

Its features are:
Weight: 380 gr
axle arrangement: B’ B’
drive axles: 4
weight-bearing axles: 4
axles with traction tyres: 2
weight/axle: 95 gr
Adhesive weight: 238 gr
Motor type: DC Can motor

Hello everyone

The next locomotive with 382 gr is a classic märklin, the 3032, a very heavy locomotive for how small it is. But it really only relies on the extreme axles, this means that to connect to the electrical ground there are only two wheels and when there is a detection track we have only one wheel for contact (I have installed the diode trick in the detection tracks but it does not help much), this makes it very sensitive to power cuts. (It helps to tow a metal train because the whole train through the metal hooks help with the ground connection). It is digitized with a LokPilot.

Its features are:
Weight: 382 gr
axle arrangement: D
drive axles: 2
weight-bearing axles: 2
axles with traction tyres: 2
weight/axle: 191 gr
Adhesive weight: 239 gr
Motor type: SFCM

Hello everyone

Today we are going to see the BR 65, märklin 39650, the second lok insider of 2018, a model desired and awaited by many fans. The locomotive itself is a marvel of details and the operation is very smooth, the sounds are also very good, but I was a little disappointed in some respects. The locomotive has problems to pass through normal turnouts of track K and M, it stops and in some cases remains blocked, I must look at this later in detail, and the two bogies seem to have a lot of freedom of movement are easily out of the way, there are times when the locomotive hitch when driving through curves of R1 rubs or pushes the wheels of the bogie making this derailleur. I also have to look at this in more detail. On the other hand the traction results I expected better but they are not bad either.

Its features are:
Weight: 388 gr
axle arrangement: 1’D2’
drive axles: 4
weight-bearing axles: 6
axles with traction tyres: 1
weight/axle: 65 gr
Adhesive weight: 113 gr
Motor type: DC Can motor

Hello everyone

The next locomotive with 400 gr of weight, is the V140 märklin 34210, this locomotive is entirely of metal and originally brought a delta decoder, but the result was not satisfactory, and I contacted Huib Maaskants because he had an article of the conversion of the Trix model of this locomotive, and I converted my 34210 to 5 pole motor and decoder Lokpilot v3, to know more about this click here.

Its features are:
Weight: 400 gr

3374
Hello everyone

The next locomotive is the BR 216, märklin 3374, this locomotive was initially delta, but as I did not like its performance I changed the engine to a 5-pole and installed a LokPilot decoder. I expected that the results of the test were going to be better, the characteristics of my model limit much the performance of this locomotive, dragging wagons in the section of R1, when leaving the curve in S begins to skate and I have not found way to avoid it, can drag more wagons but in that stretch of track slides, is a reality. And something similar has also happened to her pulling in the section of R2.
In the normal circulation of my layout (on the right) the slope in R2 (outside) is used to go down, and the R1 (inside to go up) this might seem an inconvenience really is not, because in the tests you can see that the results are better in R1 than in R2, in general for almost all locomotives.

Its features are:
Weight: 400 gr
axle arrangement: B’ B’
drive axles: 2
weight-bearing axles: 4
axles with traction tyres: 2
weight/axle: 100 gr
Adhesive weight: 200 gr
Motor type: DCM 5 poles

39567 1st part
Hello everyone

Several weeks ago I uploaded the last test, I have not forgotten this thread, quite the contrary, I have been doing many tests. This has begun with the tests of the kroko insider of 2018, the Ce 6/8 #39567, it must be said that this locomotive is a wonder, the amount of details that makes it unique, in addition it is equipped with two engines, each in one of the bogies, and has many, 28, functions, most sound, but also raise the pantograph, telex couplings, lights and sounds. The traction tires are in middle axle of the bogies. The ride is smooth and quiet. It is a must.

Its features are:
Weight: 406gr
axle arrangement: (1’C)(C1’)
drive axles: 6
weight-bearing axles: 8
axles with traction tires: 2
weight/axle: 51 gr
Adhesive weight: 152 gr
Motor type: DC can motor

It pulled about 20 cars through the section of R1, however I did not record it on video and when I went to repeat the test the locomotive began to skate at the exit of the curves in S of R1, I removed one car and another and another until you get to 12, and this is the video
R1 pulling: 12 cars, train weight: 1602 gr
[YOUTUBE]
[/YOUTUBE]

In R2 I had more luck and I recorded all the attempts, however I had many problems, wagons with short hitches and short hitch kinematics, stretched this mechanism dangerously and for example rheingold cars derailed me several times, I had to be moving the relative positions of the wagons inside the train and make very smooth starts, you can see the video

R2 Pulling: 22 cars
[YOUTUBE]
[/YOUTUBE]

I also had power cuts where before the locomotive had passed perfectly, the maximum number of wagons was 24, a train with a weight of 3106 grams and a length of 410 centimeters.

R2 Pulling: 24 cars, train weight: 3106 gr, with a train length of 410 cm
[YOUTUBE]
[/YOUTUBE]

This has made me rethink these tests, until now I had used the wagons that I currently have in the layout. But I realized that mixing short couplings with the relex couplings of marklin does not seem a good idea, and also that the elasticity of the short couplings of marklin is not good for these tests. So I have chosen the 46xx series wagons of märklin as well as the 24 cm cars, they weigh quite a lot and I think they offer good circulation characteristics, and I am currently testing with this material. I have to choose carefully the position of each wagon inside the train, but I have managed not to derail, then you have a video with the locomotive 39567 dragging a train of 18 wagons on the section in R1, and can with more!

Antonio,
Its a dismal weight of 402g, you would think its all made of metal the weight would be higher., also 4 drive axles what happened with the other 2 ?

most layouts couldn't accommodate longer trains so it looks like the trend for manufacturers to produce heavy freight locos is a myth, as in your case its a shunting loco so it could be used as an excuse. its nice to know the details are impressive, I wish one day they can put all important parts into 1 loco, weight, traction tyres and details.

That model has nicer detailing than my 2014 double set of crocs but it is quite similar mechanically. The prototypes dictate the small size of the models and even though mine have cast metal chassis and bodies they do not weigh a lot, which necessarily limits their traction. I compensate by running my crocs as a multi unit consist although that option is not a solution in most cases. On the other hand my Big Boy and Challenger are based upon massive prototypes and they have high adhesive weight and amazing traction.

In HO scale there is a finite limit to just how heavy a loco can be, regardless of the materials used to make it. I think that the real lesson is that your track needs to be laid as well as possible and provide an environment conducive to good running, regardless of the tractive abilities of your models.
Regards,
Jim

I have almost all Märklin and mostly HO, although I do have a small number of Z gauge trains!
I have models from Era I to Era VI, but I try to focus on Eras I & III. Whoops, that one got away from me. Let's just say I focus on cool trains, regardless of the particulars :-)
So many trains and so little time.

Hello

I weighed the locomotive again and obtained a result of 406 grams.

20190618_110418.jpg

As for the axles of each bogie, I was wrong, and all axles are supported on the track, therefore has 6 axles with traction, in addition the grip rings are on the central axis, I have corrected the previous post data.
I will be out for the next few days, when I come back I will continue with the tests.

39567 2nd part

Hello everyone


I continued testing the 39567, and I had some problems that I had to solve, some in relation to the high temperatures we have in Madrid and others of a general nature.

In the R1 section I managed to get the locomotive to drag 21 wagons with a weight of 3545 gr. and a train length of 5.05 meters.



The locomotive has the necessary power to pull that and more, the fundamental problem is that the wagons derail in the slope in curve R1, the track was a little superelevated and I have tried to level it, but it has not improved the situation.

I also found contact failures between the locomotive and the track and the consequent stops of the locomotive, this is not new, but after cleaning the track, the locomotive sometimes skids and this falsifies the result.

On the other hand, if the train derails due to its weight and length, this fact makes me question these tests, since this locomotive is not the heaviest, there are still many and heavier to test, but the result I know what will be, train derailment. I can look for other wagons, inside my collection, to see if they don't derail, but this makes the tests, and these mails are spaced in time. A dynamometer would be fine but I don't have one and I don't want to buy one.

it will continue

39567

Hello everyone, good morning
I've been doing more tests with the 39567 in the R2 section, and well, the wagons don't derail me due to the lateral force in the curves, but nevertheless the locomotive, from time to time, and for no apparent reason, skates. Both the wheels and the track are perfectly clean.
So this is the final result for this locomotive, 21 wagons on the section in R2.

This train weighs 3545 gr and measures 5,05 meters, which is a little more than what the ramp measures, so there is always a part of the train in plain.


Next Locomotive, märklin 3039.

3039 Märklin BR 110

Hello everyone, good morning

Today we are going to see the märklin version of the BR 110, the 3039, a classic that began to be manufactured in the 60s and of which many copies have been produced. It's a robust, elegant locomotive that never gives problems that circulates well on all tracks and can with (almost) everything. The locomotive was initially analogue but I digitalised it with a 5-pole motor and a LokPilot decoder. The loco was manufactured in 1978 but I bought it in 1998.

Its features are:
Weight: 425 gr
axle arrangement: B’ B’
drive axles: 2
weight-bearing axles: 4
axles with traction tires: 2
weight/axle: 106 gr
Adhesive weight: 212 gr
Motor type: DCM 5 polos

3156 Märklin BR 140
Hello everyone

Today we have to the 3156, model of the BR 140, a locomotive practically equal to the 3039, the only difference is the color. My locomotive was factory equipped with a DCM motor, and I digitalised it with a 6090 kit, i.e. the 5-pole motor and a 6090 decoder. It has a very smooth operation and is very silent, the result of traction tests are very similar to those of the 3039, although somewhat higher, it may be that the traction tyres of this locomotive are in better condition than those of the 3039.

Its features are:
Weight: 425 gr
axle arrangement: B’ B’
drive axles: 2
weight-bearing axles: 4
axles with traction tires: 2
weight/axle: 106 gr
Adhesive weight: 212 gr
Motor type: DCM 5 polos

3518 Märklin BR 18.4

Hello everyone

Today we have this locomotive, the BR 18.4, model märklin 3518, this locomotive has a rolling 2'C1', and originally it was analogical with 5 pole motor and an electronic circuitry that allowed it to have the maximum speed and adjustable inertia, when the 6090 decoders came out I thought it was time to digitize it and I installed one of these kits of motorization and digitization, so currently the locomotive has a DCM motor of 5 poles and a 6090 decoder. The locomotive has a very smooth running but less power than I thought.

Its features are:
Weight: 475 gr
axle arrangement: 2’C1’
drive axles: 2
weight-bearing axles: 4
axles with traction tires: 1
weight/axle: 119 gr
Adhesive weight: 148 gr
Motor type: DCM 5 poles

When you digitised it did you also change the armature? The 5 pole armature in the 35xx series analogue locos is quite different windings to the 5 pole armature used in digital conversions. If you didn't replace it that may account for a lack of power, although not replacing it tended to burn out the decoder as it is quite low resistance.

Hello, good morning

Yes, when I digitalized the locomotive with the 6090 kit, I changed the armature or rotor.
Then I was testing that 5-pole rotor on other locomotives, with pretty bad results, and I definitely discarded it.

37061 Märklin BR E17

Hello everyone

Today we tested the locomotive märklin 37061 reproduction of BR E17, this locomotive was model insider 2011, and has some particular features, the skate is located under cabin 2, and when it goes forward takes cabin 2 to the front, therefore reverse the cabin that goes ahead is 1, this feature has other locomotives such as 3768 (E18) and BR 216 (3374), but it is something I have never known why it was so.

Another thing that has nothing to do with traction but that has missed me, is that although the locomotive has two sounds, whistle and engine fans, it only has one sound channel, this means that if we carry the noise of the fans (engine) activated and give the whistle, in what is sounding the whistle the fans stop and are not heard, which seems to me, in a locomotive insider, a botched, in 2011 and long before there was enough technology for the decoder to have several sound channels.

In addition the 37061 E17 which looks a lot like the E18 3768, has the same length, and the same rolling, is much lighter, and I have found a certain tendency to skate, also when pushing a train the front guide axle (depending on the direction of travel) tends to rise, and rises, making the locomotive derail when it reaches a curve.

Its features are:
Weight: 475 gr
axle arrangement: 1’Do’1’
drive axles: 2
weight-bearing axles: 4
axles with traction tires: 2
weight/axle: 119 gr
Adhesive weight: 238 gr
Motor type: DC can motor

Why some Märklin locos run with cab #2 forward has long been confusing to me as well Antonio.

There may very well be an explanation that makes perfect sense but I have yet to find it.

Perhaps someone here can provide an answer.
Regards,
Jim

I have almost all Märklin and mostly HO, although I do have a small number of Z gauge trains!
I have models from Era I to Era VI, but I try to focus on Eras I & III. Whoops, that one got away from me. Let's just say I focus on cool trains, regardless of the particulars :-)
So many trains and so little time.

On the other hand when pushing the train some cars derailed.

Its features are:
Weight: 478 gr
axle arrangement: (1’C’) (C’1’)
drive axles: 2
weight-bearing axles: 4
axles with traction tires: 2
weight/axle: 120 gr
Adhesive weight: 239 gr
Motor type: Soft drive sinus motor
