I am gonna propose this route. The route is 47miles long. This would be set in 2014. Rolling stock: Class 365 These trains would go up to kings lynn they have four cars and use OHLE. Class 313 These trains go to Welwyn Garden city or letchworth garden city. They use OHLE. They also terminate at London Moorgate Depot: Hornsey TMD Map
47 Miles from King's Cross to the same guy's Lynn? That's more like 100 miles. As much as I like that proposal... as long as DTG doesn't change their approach toward route length, we should consider ourselves extremely lucky if we get King's Cross to Cambridge. And even that would be way beyond average. Might as well turn out to be London to Stevenage or Hitchin.
