Channel Tunnel
built 656 days ago
At 21:52, a second train (consisting of a single locomotive) entered the tunnel behind train 7539. A few kilometres in, the driver encountered smoke thick enough to make him slow down. At the same time, one of the fixed smoke detector units in the tunnel triggered a confirmed alarm, indicating to the Rail Control Centre that there was definitely smoke in the tunnel.
