Hi Tim. Very good! Are you actuating the uncoupler "by eye" (ie when you think a coupling is in the right position), or are you using some form of detection?

I would try the uncoupler on the "up" side. M couplers are designed to stay uncoupled while you push a wagen into place, so they will remain uncoupled unless you back up and then pull forward into the coupler. This might allow you to make the hump lower as now you are uncoupling at about 1/2 the hump height. Turn the set around on your hump and let them roll down the other side for a quick test.

That also eased uncoupling as the slack is taken out of the couplers while cars are pushed uphill.

I like :
- The forum member panting when starting the exercise.
- The last sequence with the car-mounted camera documenting the last run up to the stub.
;o)

Now seriously: Well done.

Tim all I can say is, "I want that!"

What a fantastic idea!

Elegantly made in it's simplicity and realistically portrayed in it's functionality!

I'll be the second to say after Danlake:

I would agree with having the uncoupler on the 'up' side. There is another reason for doing this - the couplings, or at least the older Relex ones, were designed so the pin had a bit of a slope away from the adjacent car so it is more difficult for the loop to leap up and uncouple on rough track (this is illustrated in old catalogues from around the 60s). I don't know if this is still the case with the close couplings, but I suspect your wagons would not uncouple so nicely if you had a bunch of the HOBBY range wagons.

However they uncouple a lot easier if the couplings are not under tension, i.e. when the wagon is being pushed up the hump.

But excellent video illustrating the concept.

Tim,

Very very nice work! You have just the right amount of slope for the travel and speed of the wagons.

Nice space you have as well.

I tried that, knowing in theory marklin couplers stay uncoupled, but the problem is the speed, you have no control over the speed of the descent and it caused numerous very heavy collisions in the yard. In 1:1 scale they have reatarders or a break man to slow the wagon. So to try and preserve the wagons I went for multiple uncouplers on the downward slope.

Hi All

I have now been getting quite a bit more expierence with the coupling on the slope. I have found that the Marklin close couplers never have aproblem when uncoupling on a downward slope, others do. I have now changed all the couplers on the freight wagons to Marklin close couplers and it all works well although some of the Piko wagons have troubles on the corners and points when close coupled.

Maybe Roco couplers are the solution.

Tim,
Great display and video. The only problem is... how I can fit one into my layout!

Thanks for the great video. A working hump classification yard has been on my wish list for a long time.

Yours works very nicely and the video gives me new inspiration for eventually making one of my own.

Cool
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.

Hi Tim
This has been a lot of water under the bridge. Your Marshaling yard is very good and surely has progressed a lot.
I have a marshaling yard that is much smaller but I worked on an automatic detection of the couplings to activate the decoupler by an optical gate I made myself
Here is how it looks
BarriereOptique Light.png
A standard phototransistor is connected to the entry of an S88 and the zero (upside down T) and the Infra Red diode is near the rail.
The photo-transistor is mounted on a mast and a little tubing protects it from ambiant light
Here is a video of it

Cheers
Jean

Hi Jean

That looks great, the trouble I had with only one uncoupling ramp, was to control the speed of the wagons. Different wagons move at different speeds depending on weight, number of wheels and complexity of points they have to pass. In reality computer controlled retarders control this, but as yet I can't find a way to do it at HO level apart from multiple uncoupling ramps. Any way its fun and gives more interest to the layout.

Hi Tim
Here are my findings
The variations in rolling qualities are certainly an issue. I did some cleaning of the bearings and sorted out some wagons with poor running qualities and also those too heavy (cranes, etc).
Concerning the incline and bumping speed:
- I installed the tracks on adjustable height spacers until rolling was uniform on each track
- foam cylinders where installed on the bumpers to avoid hard collision

Installing computer controlled retarders is attractive and feasible but with mechanical tooling. Speed measurement could be by optical gates.
Not for me because I don't have the mechanical tooling (Milling, Lathes,..) nor the space on my layout
Cheers
Jean
