I'm not alone in saying that we are massively short on UK traction! Many, many players I come across on non-dovetail groups on Facebook share my opinion / frustration that we do not have the beloved Class 91 in Train Sim World! It's a very famous train on our railways. We have the East Coast Mainline portion that it tested on, that it runs on, and the line just feels like it's missing something with no 91! I personally would love to see more pieces of this line appearing in game, but there needs to be a 91 in game! I also wish for more classic Diesel Electric & Diesel Hydraulics locomotives. I'd love to see a Class 55, and another Deltic. ... We're also really short of modern freight power - too many of us are fed up of seeing the 66 pulling everything!!;
Deltic would be a Day One purchase for me, along with some Mark Two aircons to run behind it. A Class 56 would also go well on TVL, maybe other routes too. Even a Class 60 would break the sheer monotony of the Class 66.
Class 70 and 69 for modern freight services. Class 55 Deltic for ECML is also needed, as well as a Class 56 and Class 58 for more freight operations on the Tees Valley Line Route. Also, LNER A4 (Mallard, especially), LMS Black 5, GWR King, Hall, and Castle-Classes should be added for more steam power.
Way too many missing classes at present. Locomotive dlc is very thin considering the number of possibilities that could already be used. That is without any of the upcoming routes.
