Imagine you start a scenario, IE a time table but it’s YOUR time table for the day with all the routes you’re gonna drive for the day. Maybe you start the day off with a return run on the Lewes shuttle, have a break att Brighton where the AI driver greets you and take the train over. Then you get on a service to Eastbourne. Get relieved for a break at Eastbourne and run a Brighton service as far as Lewes again. Get off and get relieved by an AI driver again who continues the run and you change platforms and wait for your service to the seaside. You do a return run to Brighton and your day ends with parking your train at the platform to be picked up later for a return run only now the schedule is thinned out so you park the train instead of being relieved by an Ai colleague. How would that sound for realism?
