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. So far I have made a weekday timetable with engineering works and I may make a normal timetable in the future. Feel free to make a timetable yourself for this simulation as well! 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.
