I actually used six axles on each end of my K5 Leopold railway gun, which is
85 studs long and can still negotiate the tight LEGO track curves. Each truck
is made up of three axles, but the method I used could actually be extended
indefinitely.
All axles are grouped in sets of two ... these two-axle groups are linked to
each other with the 2x2 plate with a half-round side with a hole though it.
Ummm, the piece that was used on LEGO dcastle drawbridges to run the string
through :). These are overlapped and connected with a technic half-peg.

Each set of two axles can rotate around its neighbors. Here's a picture of the
whole thing going around a curve:

The only restriction on this method is that there needs to be a stud's distance
between each axle piece.
With six axles on each end, the flatbed section makes a visually appealing
snaking manuever as it goes through reverse bends.
