I’d love to see the route from st Pancras to Ramsgate or Chatham but I don’t know what depot the trains will be at
The line carries international passenger traffic between the United Kingdom and Continental Europe; it also carries domestic passenger traffic to and from stations in Kent and east London, and Berne gauge freight traffic. The line crosses the River Medway, and tunnels under the River Thames, terminating at St Pancras International station on the north side of central London. It cost £5.8 billion to build and opened on 14 November 2007.[4][5] Trains run at speeds of up to 300 kilometres per hour (186 mph) on HS1. Intermediate stations are at Stratford International in London, and Ebbsfleet International Station and Ashford International in Kent. International passenger services are provided by Eurostar, with journey times of London St. Pancras to Paris Gare du Nord in 2 hours 15 minutes, and St Pancras to Brussels-South in 1 hour 51 minutes.[6] As of November 2015, Eurostar has used a fleet of 27 Class 373/1 multi-system trains capable of 300 kilometres per hour (186 mph) and 320 kilometres per hour (200 mph) Class 374 trains. Domestic high-speed commuter services serving the intermediate stations and beyond began on 13 December 2009. The fleet of 29 Class 395 passenger trains reach speeds of 225 kilometres per hour (140 mph).[7] DB Cargo UK run freight services on High Speed 1 using adapted Class 92 locomotives, enabling flat wagons carrying continental-size swap body containers to reach London for the first time.[
The 395s are based at Ashford, UK based 373 and 374s are at Temple Mills near Stratford. French 373/4s are Le Landy near Paris and the Belgian sets are based near Brussels
In all seriousness this won't happen it's to long but I would say there is a chance of Maidstone West to London St Pancras Internationalas this is only 45 miles so within reason.
In terms of a depot on this route it doesn't need one CN Oakville Subdivision Didnt have a depot so why does this.
