70 9-Car Class 345 trains manufactured by Bombardier (now Acquired by Alstom) is probably enough to serve the Elizabeth Line plus with a possibility of 10-20 more Class 345s if the extension from Abbey Wood to Gravesend does get the go ahead.
I mean HS1 from London but Thames link does good service from Abbey Wood also southeastern from charing Cross to gravesend go back HS1 southeastern high speed trains from St pancas does very good service.
Alright, the naming of the Elizabeth line sucks. It makes it sound like a tubs when its not one, because "line" is assimilated to underground tube line, and this documentary fell for it. Apart from being an underground train (on parts of the route), the Elizabeth has little in common with a tube line, and has a lot in common with national rail services, even running on the same track, so it should just be called crossrail to avoid confusion. Unfortunately, the uk is stuck with an archaic monarchy and hence we get the Elizabeth line...
@@wisehat_yt well the main difference there is officially, its called the overground, and officially, there is no seperate name for the different lines...
