Hi all, I have a query on how dwell times should work. The scenario is that a train, called lets say 1Z00 arrives at 1200 and its associated ECS 5Z00 departs to sidings at 1215. So as to enable me to clear the platform more quickly if I so desire I have shown 5Z00 as a "d" stop, i.e. 12d15 The issue is that after 1Z00 arrives, the TRTS activates within 30 seconds of its arrival which is not realistic. I have set up a custom dwell time of 3.00 mins in "terminate forward" box for 1Z00 but it makes no difference. Can anyone tell me what I'm doing wrong?

Writing rules can be as much of a pain, but I see that TT developers often provide rules such as 5Z00 will not depart from Kings Cross until 3 minutes after 1Z00 has arrived.

3 minutes is just an example. The minimum dwell time would need to be sufficient for the driver to close down the cab they have arrived in and get themselves, with their gear, to the other end of the train and settle in. That could be as high as 10 minutes so a 15 minute turn round would be used just in case the driver needed the loo or something delayed them.

Dwell times Vince are used when writing timetables for such things as coupling & uncoupling. In the timetables I write 'dwell' times into the timetables for eg: coupling/unclupling of locos, coaches & wagons usually 1 min. For DMUs I set coupling/uncoupling to 2 mins because of the vacuum pipes were pretty hard to do. For EMUs & Sprinters I tend to set them to 30secs. For crew changes there is now a tack box on the tt data page when creating a timetable & when you tick it it adds 'C' in the arr. times & dep. times as in WTTs, but you also get a telephone to the signaller advising him of when the forward crew will be ready as you do in PSBs at Saltley & no doubt Derby when you were there. Which makes me think i worked with you at Nottingham ROC when it was under Mainline Freight as Senior nfastructure Controller when I was on the Resources Managers desk.

Hi all, Well I've experimented a good deal and found a solution which works for me. Example : 1Z00 arrives 1200 : 5Z00 scheduled to depart at 1215 but I want the option of it being able to go earlier, if necessary to clear the platform. After a lot of experimentation I found that on the 5Z00 timetable if I check the "set down only" box and add a suitable dwell time to the departure time (I used five minutes) then the two combined mean that 5Z00 is ready to depart 5 minutes after the arrival of 1Z00 if I so desire it. Similarly I use the set down/dwell combination at Chaddesden for ECS say from Derby Station to Etches Park via Chadd. This means that if the ECS is early then it arrives at Chadd early, stands for the set "dwell" time (7 minutes in this case) before being ready to roll again. Hope that's clear.

Is this the same issue, and was the cause ever discovered? Last edited: 23/04/2017 at 17:03 by Danny252 Reason: None given Log in to reply |
