Please help me understand speed restrictions on bridges. I understand weight restrictions, but I don't understand speed restrictions.
If the train is going fast it will cross the bridge quicker, going over it slowly will mean the weight distributed on the bridge will be there longer.
I assume it has something to do with vibration.
I did a quick google but nothing comes up in relation to why bridges have speed limits.
Thanks.
