Just wanted to clear up a few points about the operation of Baker Street SCC. In a sentence: how is it operated?
Obviously you've got the large overview diagram in front showing track circuit occupancy, relative location of automatic signals and aspects of all controlled signals. Then on the desks you've got your 'VDUs' that you can use to have a look at specific areas in more detail and on there you can see train numbers and things, but when it comes to the actual operation of the railway, how's it done? I understand there are local site computers which operate the service in accordance with the timetable when all is running well. I also remember a conversation with harsig at one of the Christmas meets where he told me routes can be set manually using the VDU and the trackball but you can't take full manual control of an area, you just have to dip in and try and pre-empt the computer. Sadly I didn't have my notepad with me so I can't remember very much else of the conversation but I assume the standard principles apply and you can call up the timetable trains are running to and edit a particular trip to, say, get the train to turn short at Moorgate. I would imagine you can also set up auto reversing at some places, maybe King's Cross for example, and so on. But I noticed in a picture www.flickr.com/photos/llangollen_signalman/8438132236/ three visuals with slightly more old-fashioned labels: FCFS (First Come First Served) NOOT (No Out Of Turn) and NORM. That suggests to me either that there are a few other modes available (at least at Baker Street), or that the whole timetable editing thing isn't actually used at Baker Street. Can anyone help clear things up?
