Thameslink For Southeastern High Speed

I've done some research and Thameslink run on the portion of Southeastern High Speed to Rainham So I think the Class 700 for Thameslink Should Be added for Southeastern High speed

 

I'd love to see an extension along the Main Line with Thameslink and Southeastern up to Charing Cross, Cannon Street, and Kings Cross.

 

It would be unlikely that the route would receive an extension although this would be a nice idea

 

They could also extend the line to Charring Cross for Southeastern 357's too.
