Apologies if this is already possible (I'm really not at all up to speed on timetabling). jc92 in post 157949 (Doncaster 1981 Summer Weekdays) said: Cambridge - Unlikely to be done. currently insufficient information and it depends on any revised simulation including the Spalding-March which is out of scope of the PSB era. Clive replied: The revised Cambridge will cover the same area as the original one. The section between Manea and Peterborough is a very simplified one intended to provide just enough to connect it with the Peterborough sim and to allow trains to originate or terminate in the March area. If you want (say) Spalding to Ely trains over the old line, then just have them enter/leave at one of the yards. That's the best I can offer; sorry. How about rules that can reference trains running in chained sims (but won't apply when no chain in place). So an Eastern Region mega-chain that had Cambridge, Peterborough and Doncaster might have trains entering Doncaster that had run in Cambridge. If it were possible for rules in Doncaster to reference a train's exit from Cambridge, even though Ely - March - Spalding - etc weren't 'in-sim', a train delayed in Cambridge would carry a delay to its Doncaster entry. A further refinement would be to have a degree of randomness so trains making up time could be accurately simulated. (Also perhaps a degree of non-randomness so the later a train leaves Cambridge, the more delay it's likely to pick up before Doncaster to simulate the impact of lost paths, crew changes that have to be replanned as the booked crew reach the end of their shift, etc. etc.) Could be a bit burdensome for timetable writers, I accept. But the chatter on here suggest there are some writers whose quest for accuracy would grab this with both hands! Log in to reply |

This is potentially tricky, as recovery actions will vary on individual circumstances and the whims of delay attribution managers! If the train is late it could be caped early, or diagrams swapped midway with a unit coming the other way, or end up being even later due to missing its path and being stuck behind slow freight!
