This would be a nice add on as the new elizabeth line is based on. Also the old trains that still run on this route is now 41 years old you can also add the route to south end on sea. I love this route and will be so thank full if you add this route
London Liverpool Street to Southend Victoria with the Southminster branch is an ideal route size. Which could include the Class 345 and 720 'Aventra' EMUs, and possibly a retro pack with a Class 315 and 321. The tricky part is obtaining permission to use the Greater Anglia logos, since all previous DLCs featuring this TOC have been unbranded.
