(...) I'd tend to think that it is a electrical issue. I have hauled 92(IIRC) cars with a single motor- so, you should be able to manage 4 with one motor, under a suitable engine (reasonably heavy). Do the wheels slip on the engine? or does it just (...) (23 years ago, 30-Jul-01, to lugnet.trains)

(...) [snip] (...) One last hint: if the wheels sets are quite old and have been used for most of the time under heavy duty, then they might have evidently wear in their bearings. The 9V wheel blocks are using "tip bearings" (sorry I have not found (...) (23 years ago, 31-Jul-01, to lugnet.trains)

(...) I went back and looked at what was happening again. The problem is definately slippage and not lack of electrical power. I added 2 of the weight bricks and that helped quite a bit. I was able to pull the 4 cars from 4561 then with just the one (...) (23 years ago, 1-Aug-01, to lugnet.trains)

(...) under (...) Thanks Larry, the direct back-translation of needle bearing would be "Nadellager" in German, but Nadellager has a completely different meaning here. That is a roller bearing with very fine (long and thin like needles) cylinders (...) (23 years ago, 1-Aug-01, to lugnet.trains)

(...) <try a ramp, here's how> Excellent advice. If after proper weighting, you are still struggling to get things moving, there is a problem. Ben's test is good. Also examine individual wheelsets. If you flick a wheel with your thumb, it should (...) (23 years ago, 1-Aug-01, to lugnet.trains)

(...) Let me apologise. I think I exaggerated. 10s of seconds is a bit much. I just carried out a test with several wheelsets that I consider to be quite free rolling (when placed on a car, that car will go many feet of straight track if level and (...) (23 years ago, 4-Aug-01, to lugnet.trains)
