I think that the 185's could do with being lenghtend upto six cars then this would free up some other units.
Also as iam ver impresed by the 185's ithnk that they are the wrong type of train for the length of routes they are working.
As DMU's arn't really built for such Long distance where as something like the 222 Medrians would suit most of the TPE routes namley Liverpool-Scarbough-York etc.
In my opinon thye should have gone for something Like a 223 which would be pretty simmler to a Mederian but built to a Six or Seven car formation and of FTPE's specification and prhaps one whole carrage of first class accomadation.
185's in my opinion should have gone to Northern for Express Services to Manchester and Blackpool From Liverpool Lime Street etc.
Also the persons from the DFT need to get from behind there desks and start seeing the railways in the real world.
