I would tend to say that when we are talking "longest train" that there
ought to be two categories:
The "pure" category should require all motors be on contiguous units
located at the front (so as to allow multiple units but not allow
spacing the motors along the length of the train).
The "pure fun" category lifts the restriction, and anything goes.
Spacing motors out every 15-20 cars would allow quite long trains. I
think you're eventually up against the limit of how much current the
speed controller can supply.
I would be quite amazed if one could get a 60 car train moving without a
pulled knuckle, unless one either started on a downgrade or gave some
manual assistance at the rear. Not saying that it's not doable, but I
definitely would be impressed, and probably would want some "proof", all
in good fun(1)
To Ben's point, I think you really want to avoid all single axle cars,
they have higher rolling resistance since their wheels are not nearly as
tangent to the curves.
1 - note that the last time I said something couldn't be done, we got a
rather stunning model out of it... What else should I claim isn't
doable?? :-)

| (...) What about the real ones with mid train helpers? CP Coal trains in the rockies used to (don't know if they do any more) get 12 3000 HP engines, 4 front, 4 mid, 4 end. They even had a big pileup from a little mistake that they made (and you (...) (25 years ago, 21-Dec-99, to lugnet.trains)
