Hello train folks. I haven't done any Lego train building before, but I have
an Idea for a Project. I've gotten a couple of train sets and have a few
more on order, but in the meantime, and before I get too far with building,
I've got some questions about power.....
First, my plan calls for a train of about 7 cars (plus engine). 8 wide, I
think. Will one motor be able to pull this easily, or would two be better?
I found a few posts about super-super long trains, so I'm hoping this
question is laughed at. :) But Todd's search engine sucks *grin* so I've had
trouble finding more clear answers even though they're probably in here
somewhere.
Anyway, if the answer is two, should both of them be in the engine, or is it
okay for one of them to be at the end of the train? I can imagine some
problems with derailing from pushing instead of pulling.
There is some convenience in having the motor at the end: I want to have
some powered stuff there, and I don't want to run a wire down the entire
length. So that brings up the final question: are there any trucks which
conduct power but don't have a motor? If having a motor at the end does
indeed present a problem, that'd be nice.
Thanks for any pointers!

| We at LUCNY run long trains - 6 wide - but often 30 pieces of stock long. Our experience is you have to have a rear driver else the magnetic couplings are likely to give out. We have never had problems with the pusher squeezing the intermediate cars (...) (20 years ago, 30-Jan-04, to lugnet.trains)
