Damn, that's messy! Those poor P classes, minding their own business when knocked off the track by a stupid road vehicle. Ironically I have a friend who lives near there.
I'm just glad the drivers were unharmed.
EDIT: on the evening news earlier more info about the accident was revealed. It seems that the accident occured on an unprotected crossing, and due to trees blocking the view of approaching trains the truck driver didn't realise the train was already approaching the crossing at the same the truck did. Leaving the truck with no alternaltive but to floor it and try to beat the train, or crash. Unfortunately, the truck was towing a heavy low-load trailer which is what the train impacted with, knocking the train off the rails and jacknifing several grain hoppers as seen in the photo posted earlier.
Either way, it's a lucky escape for all concerned.
