Eurostar Paris-london And Amtrak New York To Miami

Eurostar: Eurostar is an international TGV service connecting theUK with france, belgium and the netherlands. Most Eurostar trains travel through the channel tunnel between the United Kingdom and France.
Amtrak: Adirondack train service line Montreal ,Albany to New york Penn station and Silver Service New york, washington DC ,Charleston, savannah, Jacksonville and orlando tampa Miami.

 

Could you make 2 separate posts for these two routes

 

One word, for both:

Loooooooooooonnnnnnngggg

And, more for Eurostar:

Tunnnnnnnnnell

Also, Eurostar isn't a TGV service, it's seperate. It uses TVM in most places, but isn't a TGV service.

Plus I don't see the appeal in a massive tunnel for Eurostar.
