Since some of our North American fans seem to be a bit reluctant to post here, perhaps I should give you all some information to learn a bit about the route and train's used. I have gathered some useful information about the key features on the route to help some of you become a bit more familiar with the line.
The route that is being depicted is known as the Channel Tunnel Rail Link (CTRL), or it's nickname, High-Speed One. RSC will not be making the full length of HS1, but rather the portion of it that the Class 395 high-speed emu travels on. The route starts in London at the famous St. Pancras International station. Why is it an international station, you might ask? Well, this station as well as others on HS1, serve Eurostar Services from London to Paris. Unfortunately, at the time being it appears that the Class 373 (Eurostar 16-18 car TGV) will not be created for the route. The route will being at St. Pancras international where it will call it: St. Pancras International, Stratford International (No Eurostar Services stop here despite the int'l name), Ebbsfleet International, and onward to Kent. Details haven't been released yet other than the brief paragraph on the December announcements, so I'm not sure whether or not the line will continue to Ashford International, where the 395 Hitachi Depot is- hopefully it will. It is important to note that there are no track-side signals on this route outside of the remaining signals at St. Pancras on HS1, but there are on the line to Kent once leaving HS1. TVM 430 (used on TGV's) are featured control/signalling systems on both the Class 395 and 373. A unique feature about both units is they can use both overhead wires or a third rail (or at least the 373 use to to get into London). While the 373 no long has to use third rails, the Class 395 does on it's way to Kent after leaving HS1. Overhead wires are 25Kv and the third rails used are 750Volts. While the Eurostar appears to deal with the very steep gradients on the line very well from what I have seen or read, the Class 395 is a bit under-powered for the grades. It has about 16HP per ton, 2 more HP per ton than the 390, the difference being the 390 doesn't have to deal with such steep gradients. However, the 395 is still the most powerful EMU in the UK.
Here are a few pictures of the high-speed units/trainsets used on the line.
