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 the
translation for "Spitzenlager" in
any dictionary). I mean a bearing as used for e.g. in good mechanical clocks.
These bearings are not made for higher loads, but their main advantage is their
very low friction.
But if the abrasive wear increases a certain level, then the spinning wheels
will touch the wheelblock on their top side. My friend Torsten has used some
trains in his wifes pharmacie display. These waggons had this problem after a
running time of a few month (depending on the wheight of the waggons).
I myself have bought a few used waggons from children, which have the same
problems. Maybe the wheel blocks are dedroyed in one short moment, if you try
to use the waggon as a "skateboard". Children are so creative sometimes....
So please check:
- are all the wheel able to rotate free without getting in contact with the
wheelblock.
Kind Regards,
Ben
P.s.: The record for the longest pulled train (without any extra
engines/motors within the train) is still at an amount of 126 waggons! Two
engines with 4 motors at the front and 108 beer waggons from 2126 + 18 tipper
waggons have been driven by 4 people at the 4 transformers for a few rounds on
a big track oval in late december 2000:

| (...) 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 (...)
