I’m suggesting the Birmingham Loop for TSW. The route has runs from Rugby to Stafford via Birmingham New Street and has 21 stations. Route map: Stations: 1. Rugby 2. Coventry 3. Canley 4. Tile Hill 5. Berkswell 6. Hampton-in-Arden 7. Birmingham International 8. Marston Green 9. Lea Hall 10. Stechford 11. Adderley Park 12. Birmingham New Street 13. Smethwick Rolfe Street 14. Smethwick Galton Bridge 15. Sandwell & Dudley 16. Dudley Port 17. Tipton 18. Coseley 19. Wolverhampton 20. Penkridge 21. Stafford Rolling Stock: Transport for Wales Class 158 Express Sprinter DMU Transport for Wales Class 197 CAF Civity DMU
Love this suggestion, there are lots of opportunities for layers with the current rolling stock and also features a few train depots for more variety. It would be an instant buy for me.
