Heres an idea. Handlay the track on a base of copper clad circuit
board with code 40,55 or 70 rail. Just solder on the outsides of the
rail. So the wheel flanges are touching the board slightly. The wheels
will spin easier that way.
Gap the board between the rails. Fake some short ties between them.
Divide the section with gaps into three blocks A B C. Design a circuit
[or have someone do it for you] that powers A with C dead then
switches to A+B with C live. Then turns off B and turns on C with A
dead and then C+B and repeats. A block is right rail positive; C block
is left rail positive. B block switches between whichever block it's
That will wire it up so the loco on A pushes forward with no
resistance then then get reistance from the loco on C and then the
loco on C gets no reistance.
You might have to repower the locos with coreless motors. I believe
they're free spinning unless powered. [I'm not 100%]
Look at this article.
Free-rolling steam locomotive drive

Well...if you recall that sequence in the film, there was a lot of
wheel slippage in that battle of giants and I'm not at all sure how
replicate that. Just running a pair of nose-to-nose locomotives back
a short distance is not going to convey the titanic struggle depicted
I'd have to say that setting up an arrangement in HO that would
mimic the action seen in the film would be almost impossible, using
DCC or any
other powering means.
