"Euro Train" Doesn't Exist—Clarifying Thames Crossings

There is no service called "Euro Train." The term is not used for any scheduled rail route.

Actual Trains Crossing the Thames

• Eurostar (London–Paris/Brussels/Amsterdam): Uses Channel Tunnel (under English Channel), then High Speed 1 tunnel under the Thames (Thames Tunnel) approaching St Pancras.
• Elizabeth Line (Crossrail): Tunnels under the Thames at Woolwich and Silvertown.
• Jubilee Line, DLR, District Line: Tunnels under Thames at multiple points.
• National Rail (e.g., Thameslink): Crosses over Thames on bridges (Blackfriars, London Bridge, etc.).

All London Thames crossings are tunnels or bridges—no "Euro Train" brand.
