This simulation covers the South West Mainline from Micheldever to Northam Junction (just outside of Southampton Central ) as well as the West Coastway line to Fareham and the Eastleigh to Fareham line. There is a good mix of passenger trains (express and commuter) as well as a decent amount of freight trains heading to the Southampton Docks and Eastleigh East Yard. Two real 24h timetables are included: a normal timetable with a few special trains and an engineering work timetable. If there are any problems or room for improvement, let me know via Discord. Make sure to read the README document in the documentation folder for more information and tips.
