Wow, I'm amazed... that was quick. Is it trainsets that have the sounds, bridgesets, or rather TTDPatch in general?

Technically any grf file can define them. But it makes most sense for bridge sets to define the sounds, except for TTD's built-in bridges which would need a separate file of course.

In addition to the above suggestion: trains do not slow down before they enter a bridge. Especially with a wooden bridge this leads to something quite like an emergency break (under which the bridge would collapse, I feel - does anyone know wheather breaking on a bridge exerts an extra force on the bridge?). Since trains slow down before crossings... could they also slow down before entering a bridge? And while entering a depot, maybe?

in theory, using friction between train and bridge (ie braking normall on the bridge) would exhert lateral force (in direction of travel of train) on said bridge

In which direction?
Yes, there's force generated by braking, but it's a horizontal force, not a vertical force, and I would not be at all surprised if the vast majority of that force is absorbed by the rails, not the bridge proper.

Hm, yes, that sounds appealing. I was thinking of the old problem of the bridge that could exactly hold a man of 80 kilos - but not if he would jump. But of course, as trains don't move vertically, nothing should be the case here.
What about the slowing down before entering a bridge? Anyone second me on that, by any chance?
