You could also get the sausage back and bend it ;)

Perhaps not, or at least not as flexible as would be necessary
for your track. 
But having a single set of wheels in the middle increases the
problem (I've never seen that on a real train).

Would it really be that hard to model the suspension
(realistically or not)? You already have the movement of the
upper part, guided by the track, so you also already know the
position of the track. If you take the current position of the
wheels, then put the wheels on the track and stick a bit of
bubblegum between those two positions it should work nicely.
Oh, and if you work on the Thomas-like version I'd really love
to see a sausage (even though I don't eat them). :)
