For a possible DLC in the future, I would like to suggest the Chase Valley Line which runs between Rugeley Trent Valley and Birmingham New Street which can also incorporate the stretch down to Rugeley Power Station Traction, potentially look towards the Class 150 Sprinters and the Class 56s for coal train services, shunters for Bescot Yard and maybe the Class 323 for the Walsall to Birmingham stretch
A bit off topic but the Chase Line is fully electrified to Rugeley TV since 2019 and thus you can use 323s to Rugeley TV and beyond Walsall
It is but I don't think people would want the 323s and the 350s, was thinking about a more historic Chase Valley Line
