<br />If you mean the 39020, mine hasn't any problems pulling a 5 carriages long Rheingold set.

<br />that's right, I did'nt want to divert from the Topic "Mechanical problem".

<br />can you guys show a pic of the rheingold train on your layouts?

Roco Locos have nice details but the driving wheels are in the tender.

some have 3 or 4 axles with rubbertyres and als a cardan shaft through to the loco's drivingwheels, although there are no rubber tyres on the Loco's drivingwheels.
I have written to Roco about changing the locos drivingwheel with Rubbertyre but sofar have had no positive answer back.
I've even suggested it as an option but they're refusing to come to the party, saying it coul;d effect the brakepads.

so be aware of the pullingpowers of Steam tender locomotives.
If you buy 2 and use them on 1 consists of wagons, you should'nt have any probels at all.
Look at my video of the 18201:

Hi Riekus,
Your find is surprising for me. So far I only heard how Roco steamers lacks torque as opposed to Marklin ones.

By any chance, do you know how their 01 compare to their BR 44/50/52?
I've been tempted by their DR Relok models (Marklin don't have them)..

<br />An assumption is something you make when you simply dont know.I can go make a video to proof my point.Ive just done the test.My 18201 pulls 14 carriages over that incline without slipping a wheel.I can actually crawl it over there.So there must be something amiss with yours John.

Im not assuming,im telling you that no new BR01 from Marklin will pull with this Roco.Neither will 39020...modified or not.Neither will 39050.The 39010 Br01 147 wont go over there with 6 carriages.Its crap.And its speaker is blown....again.

12 carriages is no problem for the 18201....you showed a video of it running past with 13 carriages,so i dont get the point.Nope,the first Roco BR01 is arriving mid month...then i will sell the 39010.Its useless.

Hi John,
Can you have alook at the following video?

The Loco is 3/6 3602
All of my BR 18's has pulled all these cars.

Going back to the original question to this thread;

If owners (with this issue) don't mind me asking;
I'm still a bit baffled with the issue of pulling power of the 18.3 models (as in this thread) - or to strech it a bit - new construction steamers.

I don't have an 18.3, but I do have a BR 01 - which technically built to the same level of construction standard to 18.3 (4-6-2 wheel arrangement, SDS).

My repeated test continue to indicate that the 01 has no problem outpulling a BR 50, at least on a flat surface (I don't have any incline yet).

From stationary; the BR 01 pulls 10 coaches -including 2 older, heavy ones with lighting and own sliders, which probably count as 3 coaches as they're quite difficult to move - AND still pushes another stationary (braked) 400g metal test lok on the track with just occassional wheelslip - mainly due to a delayed tranfer of power through siderods to the other driving axles.

In the similar test environment (same spot on the track); the BR 50 without any train behind it had difficulty pushing the 400g lok, barely able to move it more than a couple cms even as I increased the speed steps. It just wheelspins wildly; while its straining motor hum get so loud that I decided that it's enough.

No, I don't think there's anything wrong with my 50 - as my other DCM loks don't seem to perform that much better, either. One even started to loosened itself out of its traction tyres in this test.

So to my questions;
Is the pulling power problem mainly confined to ability to climb inclines? (due to trailing wheel rubbing off on the chassis?)

Or is it that some model just have specific problem?
(but then Riekus also complain about his BR 01s...)

I know for a fact that these new generation of steamers are tad more sensitive with track designs - they don't tolerate the slightest imperfection (gaps between tracks, etc) as well as the older more hardy models.
