Comment Re:How big are these trains? (Score 1) 515
750 people can sit on the 387 metres of a London to Paris/Brussels train. They're particularly long, since they were built for a system with a serious limitation (a very-much-in-demand undersea tunnel) and the expectation of high demand.
French TGV trains carry 350-500 people. British national long distance express trains a bit more, up to 600.
There are 16 London-Paris trains per day (plus London-Brussels, and some others), from 05:40 to 20:31, slightly more than one per hour.
