Stepping stone bridges

[Brinx]

Has anyone ever built a bridge where all the track pieces had "nothing to do with eachother", all the track pieces are supported/suspended independently? For instancem I built a level yesterday in which the track pieces formed overlapping stairs, downward. Unfortunately, the "steps" couldn't handle the impact of the train slamming down on them, and the train only got to the 3rd "step" http://www.pontifex2.com/iB_html/non-cgi/emoticons/sad.gif" border="0" valign="absmiddle" alt=':('>

It looked something like this:

And so on.

hmm, sounds like a fair challenge to me, I'll let you know if I can get one to work...
