Here's a crazy idea... How about one or more of the larger Lego train clubs that attend shows set up the following layout: a 30 x 50 foot layout (or some such large size) with no power provided at all. No batteries. No electricity. Not even solar (...) (17 years ago, 23-Oct-07, to lugnet.trains, FTX) !

(...) Actually, the magnetic couplers would be the limiting factor before the strength of the person pulling the train became an issue. I'm sure someone here knows what the critical number of cars is before the lead coupler can no longer bear the (...) (17 years ago, 23-Oct-07, to lugnet.trains, FTX)

(...) Hi Bob, that assumption is not perfectly correct. In October 2006 a single 12V engine (powered by 2 motors) has pulled this 100 waggons train. (URL) A few months earlier we have made this attempt with a 9V engine pulling 61 cars. But we had (...) (17 years ago, 23-Oct-07, to lugnet.trains, FTX)

(...) Holy schamollies! That is indeed some very impressive pulling power by the 9V motors! I guess I was only making an assumption based on mis-perceptions fueled by not enough data and an unscientific guess. Boy, that's a horrible combination. (...)

(...) In May, I made a test (based on your information): (URL) loco (built after set 112-2) pulled 20 two-axle "oldschool" cars. 11 of them had the old wheels with traction teeth, 6 had various spoked wheels (years 1969-1990) and 3 had the (...) (17 years ago, 23-Oct-07, to lugnet.trains)

(...) Does the fixed two-axle type freight car offer more resistance around curves compared to modern swiveling trucks like I imagine it would? Or would it depend on the length of the car itself compared to the curve radius? (URL) (17 years ago, 23-Oct-07, to lugnet.trains, FTX)

(...) Good question - depending on my former tests, I would guess, that short 4-wheel waggons (like the lightweight barrel waggon from set 2126) with not more than 6 studs distance from wheel block to wheel block offer the lower running resistance.

(...) The running resistance is a complex issue. Its main factors are: weight, speed, distance between axles, and track type (straight/curve). On the real life trains, suspension is also an important factor. On a straight track, the movement of a (...) (17 years ago, 24-Oct-07, to lugnet.trains)
