(07 Mar 2014, 6:49 pm)BJ10VUS wrote First Eastern Counties' X1 route from Lowestoft to Peterborough uses Enviro 400s - bearing in mind this route is 107 miles long, it's fair to say a bit more challenging than Go North East's 'Tyne Tees Express' and Arriva's X93.
I would agree, and given those E400s replaced B9TLs....I'll say no more.
