Unfortunately it is too long, and the full journey takes around 2 - 2.5 hours. A better bet would be between Cleethorpes and Doncaster or Manchester to Sheffield/Doncaster. Neither of those takes too long and is within DTG's scope in regards to route length. Both would need more than the 185 otherwise it would get boring quite quick, although one loco is the best bet as that has been the same with the last few routes.
This is a very long trip looks like you are trying to modernize the Huddersfield line which we have set in 1980s but train sim classic has it in the modern version
Hi, this is not the Manchester-Huddersfield-Leeds Line, but a different line that uses the same operator and rolling stock that goes Liverpool-Manchester Piccadilly-Sheffield-Doncaster-Scunthorpe-Grimsby-Cleethorpes.
