Don't get me wrong and I'll look at it from Blyth and Ashington's double deck operations excluding the 35, the X4, X5 and 308 can cope with a Cummins engined double decker. Any other double deck route with the exception noted above, needs a heavyweight diesel engined double decker. Why do you think GNE ordered 67 of them between 2011 and this year?
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.
