Why did the Channel Tunnel fail?
Soon after the start of operations, Eurotunnel reached a delicate financial situation which resulted from the escalation of construction costs, a large overestimation of the cross-Channel market and the underestimation of the cross-Channel ferry operators' competitive response which led to a very damaging price war.
What is the speed limit in the Chunnel?
At 37.9 kilometres (23.5 mi), it has the longest underwater section of any tunnel in the world and is the third longest railway tunnel in the world. The speed limit for trains through the tunnel is 160 kilometres per hour (99 mph).
Could the Chunnel ever flood?
Another “could” question. Yes, a quake of sufficient magnitude breaking a fault running across the Chunnel “could” flood it.
