It happened 3 days ago nearby Hamburg, train vs. schoolbus:

Right behind the railway crossing the bus had to turn sharp right. It's diverted traffic, because the large Bundesstraße (federal road) is closed for roadworks.
This articulated bus was too long for that, so the 23-year-old bus driver shunted backwards. She did that too much, so the joints blocked. As it seems, she stalled also the engine.
A 13-year-old boy saw the train coming, shouted and the bus driver let all kids out. So noone was hurt, except one train-passenger had slight injuries.
