#RailNatter Episode 164: Should you go fast or slow over a collapsed rail bridge?

It's an age-old question... A rail bridge is out, only the rails are left, so do you take the train fast or slow over the bridge?

There's a lot to think about: gravity, dynamics, waves, stiffness, materials, energy, vibrations... All combine to give us the answer. But what is it? It's slow - you obviously drive slowly over the dang bridge! Anyway, hopefully this will explain why!
