Well, this was certainly a long time coming; my two cents on the London to Brighton route in Train Sim World 4.

This route was released in October 2021 as part of the TSW2 'Rush Hour' series. It's a remake of an old TS classic route, and includes the Southern Class 377/4 and Gatwick Express Class 387/2 Electrostar EMUs. The best feature of this route is easily the insanely busy timetable, with more than 1,000 playable services.
