Not a tunnel collision. The bus just drove into a stationary train outside the tunnel apparently.

Reports add that the freight train was stationary near the entrance to the Channel Tunnel and the bus was carrying truck drivers who were preparing to board the Le Shuttle service on ⁠the loading platform at ​the Eurotunnel site.

Also “Le Shuttle service” is so funny

According to the sub-prefect of Calais, the drivers were of different nationalities and were all male.

What odd characteristics to make relevant about a traffic accident.
