Would be nice if Train Simulator had a service mode like Train Sim World. It sucks to have to spend and hour building your own scenario every time you want to mimic real world operations
Use ThirdRails Real Drive to drive real world services in UK, optional at realtime with real timetable provided by RTT in Freeroam or Quickdrive scenario's. https://www.thirdrails.org/2018/07/29/thirdrails-real-drive/
