But to start with, have a read http://www.nmra.org.au/Operations/Systems Of Operation.html cursor down a bit & click on Devan and Summersett and this should appear http://www.nmra.org.au/Operations/Solly/Devan and Summersett.pdf
Ron, How long does it take to complete or do you pull the power and come back and finish where you left off? Cameron
In the past in my DC days, I used a pure sequence & train orders were like T/O TD681W below Each train had two processes from A to B & then next time B to A which reversed all wagons back to where they started. It got to the stage that some operators got to know from the loco where each wagon went to without looking at the Order, so I started to follow other modellers ideas of a card per wagon varying wagons per session and this gives a lot of flexibility. I was still using sequences but being involved in operating other layouts using graphs & timetables, I went that way. It gives again more variances so the crew do not get too used of things but it does make more work for us Dispatchers - part of the "fun" of the hobby. The other 3 layouts I operate on all have slightly different processes and in these layouts, one follows the train but on mine, due to lack of room to pass each other, trains are handed on to the next driver. Each crew member stays at the same station for 2 sessions then moves onto another station.
Er . no Cameron, my camera, while I can take a movie, I do not have the "skills" to reduce its size to fit into Youtube and even if I could, not sure what it would show. Yes, I can spend time setting up a local goods at one station, driving it the the next & let that SM shunt who in turn drives it to the main station & let the 2 operators there sort out the wagons and finally the train is driven to storage. The data on the NMRA website was the result of NMRA Convention we had here in South Australia Sept 2017 & Gerry Hopkins MMR who attended and looks after the NMRA website, wanted data so he could post it on the Net. The biggest problem I had with timetables is that my layout has a few diamond crossings on the main line and not being being able to load Excel files as attachments, unable to show the actual track plan as compared to line plan http://www.nmra.org.au/Operations/Solly/Devan and Summersett.pdf and these diamonds make timing to prevent collisions "interesting"
This is a short, concise, and accurate description of what we all have been seeing over the years. Thanks Todd you nailed it.
