Out of the tunnel and into the Light. Eurostar power car 3308, a Class 373/2 on display at the National Railway Museum in York. This car was never actually used in Channel Tunnel service. It was built for the “North of London” UK domestic service, which never really happened except for short periods. And in a sign of how fast things change, the operators of the Channel Tunnel have been sending these locomotives and the coaches that run with them for scrapping, having been in service since the tunnel opened in 1994 and now less than 25 years later being replaced by newer equipment.
