One train i'd love to be able to drive in Train Sim World is the Class 185 Diesel Multiple Unit. The units were introduced in 2006 and have been Transpennine Express's main workhorse for the past 11 years. The units are in 3 car sets and each have a powerful Cummins QSK-19 engine under each carriage, providing a whopping 2,250 horsepower for the 3 carriages. The units have worn a wide range of liveries since their introduction 11 years ago. They can be seen below.
Try This One on TS1 ....... They Are All Over The Place Up 'Ere ....... !!!!!!! https://www.vulcanproductions.co.uk/harrogateloop.html
The idea of this proposal is to get this dmu in to Train Sim World. The fact something already exists for TS1 from a third party developer is irrelevant.
I think you're jumping the gun a bit. A 185 in TS first would be nice, you can drive alot further in TS than in TSW so they could be AI on the new ECML York extension for example
