 | | 9V train motor
|
| Hi all, After discovering the hard way (by making an impossible model) that the current electric train motor model has a couple of major mistakes (the wheels are too small and the clips are too small and in the wrong place) I decided to make my own (...)

| (...) I've enough 9v stuff to keep me going for a bit but I take your point regarding the IR trains - difficult but not impossible in 7-wide. I also look on 7-wide as a wide 6-wide. I've seen some very convincing MOC examples and note that you can (...) (19 years ago, 12-Jan-06, to lugnet.trains, FTX)

I like you have found it hard but I am hoping that once I learn how to create a nice render I can share the methods. Hopefully I can present it in such a (...)
