(...) 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)

(...) [zick-zack] Hi Martin, you have added a few interesting issues into the discussion - especially the biting on straight track was more or less new for me, but of cause fully understandable. I think this is one of the reasons, why real life (...) (17 years ago, 25-Oct-07, to lugnet.trains)
