According to network rail the reasons for rail bridge strikes include:
Driver unaware of height of vehicle – 32% Lorry mounted crane arm left in the raised position – 26% Failure to drive in the centre of the road to allow for an arch – 11%
Hit a railway bridge and there’s a lot more at stake. The safety of the trains will be compromised and the lives of the rail passengers put at risk. Network rail will also actively look to recover the cost of examining and repairing the bridge involved from the party who caused the damage.
