Postals and mails usually show as Class 1 in the TTs used in SimSig. As such, the software normally despatches them at scheduled time even if they have arrived late. However, this does not reflect what used to be the real practice. There were two parts to the working of these trains at Station stops. Firstly there was the need to get all scheduled mail on board. That means that stations where trains were due to pick up mail would normally be held right until due departure to make sure that all the mail had arrived from the sorting offices. At stations further down the line where mail was only unloaded, the Royal Mail Officer in Charge would let his railway counterpart know when his work was completed and the train would be allowed to depart early if there was a path for it. The second part of the operation was the time required to load and unload the mail. By and large, the dwell times for the Mails and Postals were based on the actual time needed to carry out this work. Royal Mail Officers in Charge were very jealous of their platform allowances and would often have to take their full station time even if the train was running late to make sure that all of the due work was carried out. To make the operation of TTs more realistic as far as the Mails and Postals are concerned, each train needs a rule or two for each station. There needs to be a rule that the train cannot depart until XX minutes after arrival (XX being the scheduled station arrival to departure allowance). I'm not sure whether the SimSig software would allow the second rule to make things more true to life. This would only apply to trains on the latter stages of their journey (e.g. at Peterborough on a Newcastle/Edinburgh - London train or Exeter on a London - Plymouth train) and would allow the Class 1 train to leave early provided there had been a stop of at least XX minutes. Certainly forcing the scheduled dwell times would lock up some busy stations when least wanted, but it is what used to happen in the real world so I think we should reflect it in the simulations. Any thoughts, anyone? “In life, there is always someone out there, who won’t like you, for whatever reason, don’t let the insecurities in their lives affect yours.” – Rashida Rowe Log in to reply |

If you want the trains to leave early then you can make the stop set-down only.

Simsig has rules which you can apply in the TT. Your first rule is certainly possible. You can add a rule to tell a train arriving a location X to wait Y minutes before departing. The second rule would require a degree of randomness as to whether the train was ready or not and AFAIK, this currently isn't available. For any given timetable, it's up to the timetable writer to apply the TT rules as a TT will work without any rules. If a TT you have doesn't include them, you could always add them yourself.
