Well, I finally finished my train tables. They basically form a square 10' on a side. I'm having some efficiency problems with the largest loop. I'm having to use 3 engines to pull 4 of the cars from 4561. The loop's length is nearing 40'. What (...) (23 years ago, 30-Jul-01, to lugnet.trains)

(...) How are the engines configured? One or two 2 truck locos, well weighted, ought to be able to pull well in excess of 20 4 axle cars on a level track, even through curves (people run way more than that but this is easy to achieve). So your (...) (23 years ago, 30-Jul-01, to lugnet.trains)

(...) <snip> (...) Thanks, Larry. I'm using a 2 motor engine and a 1 motor engine. Both are ~24 stud MOCs. I suppose I should swap some motors around to see if there are problems with the motors I'm using. I first tried just the 2 motor engine to (...) (23 years ago, 30-Jul-01, to lugnet.trains)

(...) 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)

(...) Steve, LEGO® train wheels are not designed to be lubricated. The oil will destroy the rubber traction tires on the 9V motors resulting in total loss of traction (not to mention dirt buildup on all wheels concerned). Just my 10 cents (...) (23 years ago, 30-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)

(...) <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)
