Although part of the preserved collection, this route never appeared to have any add on DLC. For this reason, I would like to suggest the addition of... Class 57 and coach stock Class 59/0 and 59/1 and wagon stock Class 165 DMU Class 180 DMU Branch lines to Greenford, Brentford, Colnbrook, Windsor, Marlow-Bourne End and Henley on Thames. This would bring GWE into parity with other routes by providing more variety than present with just 3 train types and no branches. As it currently stands, GWE feels like the naughty sibling left in the corner and desperately needs some tlc.
Would be good to see all of these. I would like to see another part of the Great Western Mainline though. The Class 57 would be the best part for me. The benefit of putting it into Cornwall or Plymouth - Exeter as a section is that they ran during the summer with both the Sleepers and they also ran from Par to Exeter on Mk3 coaches as a summer special. Would mean that there would be more to do with the Class 57 other than ECS and the Sleepers. But still all great suggestions.
