Hi, A number of schedules use performance allowances, but currently this is not a facility visible or editable in the Timetable Editor. Should it be? Thanks Jamie Jamie S (JAMS) Log in to reply |

Does this mean I should be putting diamond time down as an engineering allowance in Simsig timetables? I’ve been tending to simply ignore it thusfar.

All these times are for is to identify why a train is scheduled to take longer between two timing points. Say you have three identical trains on plain line. Two take 10 minutes to get from A to B, while the third takes an extra 2 minutes. That 2 minutes should be accounted for by an engineering, performance, or pathing allowance (or combination thereof) - to indicate why this one train takes longer than the others. If the train performs well, and there are no TSRs, then theoretically it'll arrive at B about 2 minutes early.9pN1SEAp in post 123348 said:Hi,It may be useful for train planning purposes but IT systems I've seen just roll it into the engineering allowance, just as SimSig does. Pathing allowance is indicated separately in SimSig for ARS purposes. It carries the value forward over untimed locations whereas engineering/performance is not (though I might have that back-to-front). It alters the prediction calculations, anyway.

I’ve seen quite a number of TTs (on RealTime Trains) which are using both Path and Performance, or Eng and Perf, on the same timing point. So for the TT I’m working on, I have shifted the Performance allowance to whichever of the other two hasn’t got an allowance already.
