Hi, I've just noticed that trip P250-10 (Arsenal 8:07pm, Finsbury 8:09pm, Manor 8:10;30) is listed in the XML file description field as Quote: <Description>Uxbridge to </Description> What is the correct destination? Google Maps reckons there's presently an 8:11pm to Cockfosters; I don't know if that's the shifted 8:09pm service or a completely different trip, but it matches the Wikipedia listing of all off-peak trips to Cockfosters except a handful of Northfields-Arnos Grove shorts. The description for "RuisliP to Oakwood" e.g P254-3 also has a capitalisation problem. Also, am I correct in understanding that each trip only has one time for each location (barring some at Seven Sisters), rather than a separate arrival and departure time? What would the dwell at each stop actually be? Thanks, David Last edited: Yesterday at 08:31 by Anothersignalman Reason: None given Log in to reply |

Underground timetables only have one time for each location with very rare exceptions (there are none in the current Victoria Line WTT). However, they use notes in the time to indicate a booked dwell. For example, "a" between the hours and minutes of the timetable entry means 20 to 30 seconds additional dwell in the platform, "A" means 35 to 45 seconds, up to "L" means 5m35s to 5m45s (there are 23 such codes in total). There's no standard dwell time listed in the WTT. Log in to reply The following user said thank you: Anothersignalman |

For context, the reason I'm asking these is because I'm converting the XML to a graph. I did a similar conversion for one of the Aston schedules. With the runtimes rounded to 30-second increments and no dwell times, it's possible that the headways shown in the Simsig might not match reality. On the other hand, as I understand it the program uses linear acceleration, so maybe that degree of accuracy isn't worth the effort anyway? Further things as I find them, on top of the three things above: 4. Is trip V214-2E correct in running VICTORIA > VICTORIASDG > VICTORIA, or should it change ID when reversing in the siding? Same for V214-26E and V214-27E. 5. Is there a reason the runtime for V201-20E is 120 seconds, but V202-20E is 150 seconds? 6. Are there any other instances of unique runtimes within a pattern, that I haven't found yet? Contrast with V214-27, which has 120 seconds in lieu of the normal 90 seconds KINGSX > EUSTON, but that's OK because it's flagged with a different description. Another example is V214-2, with +2min dwell at SEVEN when all other trains in that direction appear to be +30sec (including the other Victoria to Walthamstow move, V203-1). Log in to reply |
