I'm old enough to remember when it was a pain to negotiate the 300 miles (500 km) between London and Paris. No more. Regular travelers in particular must appreciate the EuroStar schedule inaugurated November 14 that reduces travel time to just a bit over two hours, down from more than three hours when service was inaugurated in 1994. That doesn't include the time passengers save by avoiding the security hassles of air travel, and EuroStar's seats are considerably better too. Even before the new service, the Chunnel train was claiming a 68% share of trips between the two cities.
The faster travel times are the combined result of new high speed track in England and a new London station at St. Pancras (replacing Waterloo, which no longer has EuroStar service).
What the new service will do to the dress of the English and French remains to be seen. A stretch before, it's practical now for a Londoner to take a day off work for a same day journey to buy pointy-toed shoes in Paris. His Parisian colleagues are equally able to buy flamboyant shirts on Jermyn Street. The Business Class-like Leisure Select non-refundable round trip fare is £199 (about $400), and Standard Class is just a bit more than half that.
It all makes me wonder why the United States doesn't do something similar between Washington, New York and Boston. Amtrak's Acela Express service is a start, but cut the transit times in half and there'd be no need for the eight or more commercial flights that are in the air between those cities every hour during the day. That's a lot of kerosene.
