You either love or loathe train sims.
It might be stretching the term, but one of the most popular simulations of recent years must be Euro Truck, which, when you think about it, is a similar concept. You go from one point to another, following correct procedure in a rather untaxing way, and deliver something.
Train Sim World is the successor to the Train Sim series. If you're familiar with it you already know the premise of TSW, and its first module, CSX Heavy Haul, and you know how this series will develop. A snapshot of a particular line, its relevant engines and rolling stock.
In CSX Heavy Haul we're transporting freight on Sand Patch Grade.
This video covers the first scenario, Helping Hand, and is quite a straightforward run to collect rolling stock.
