Nottingham Resignalling

Unread postby LowdhamGPR » Mon Jul 22, 2013 10:58 am

I've put this in Signalling - Current.

Attached is a link to a Flickr set I've composed of the boxes around Nottingham which will be abolished or altered and which I'll be adding to as the blockade progresses.

Hope it is of interest.

Sneinton Box : I'm advised by the man on site today that the box is being lifted Saturday night. (27th / 28th)

Great pictures, id also like to see what this is all becoming in the EMCC as a whole, but also the new workstation. Nothing much on the EMCC.

photos by me from an SRS visit in May. By the way, I realise there are different displays - with different levels of information - on these workstations, but could someone tell me what the screen on right is, with the green/blue/cyan/orange track?

I'm in Derby on Friday for my SCAP so I may take the camera.

Thanks for the kind comments, glad to see the photos are appreciated.

Well I'd say they were various types of reminder applied except that if they showed up on the overview screen they should also show up in the detailed screens which in this case they aren't, however as the workstation had not been commissioned at the time the photo was taken it could be anything, the layout on this screen is also drawn very strangely for some reason so I to would like to know what for definate.

Lowdham GPR can probably answer this better than I but they could be a VDU screen representation of a traditional signalling diagram, to illustrate different track circuits.

The right hand screen shows the section around Netherfield Junction, and how it fringes to each adjoining workstation / signalbox.

Again thanks to John for recording the changing scene amongst the signalling fraternity.

Looking at the December timetable in open train times it would appear platform 4 will be permissive for ECS workings only - Matlock arrivals are shown to arrive there and shunt to the parcels siding, returning to the platform after the Leeds train has arrived. The connection between platforms 4 and 5 is quite a way along 5, so presumably their combined capacity will be substantially less than if they were a single platform.
;
The chief effect of the introduction of 125 mph running seems to be longer platform occupation at terminals- probably off-topic now - although it seems that they have after all been able to time most St. Pancras-Sheffield semi-fasts in front of XC trains from Derby, which I am fairly sure it had been stated was impossible until Dore was remodelled, while the fasts are largely a dead two hours WTT, advertised one minute longer!

It is for applying groups of reminders, such as EPR, STR, EPO, SEAs as applicable to whatever they have fitted there. the different colours differentiate the different group areas. There is no significance to the colours used.

And before everyone asks....

EPR - Engineering Possession Reminder (A control applied to facilitate an unconditional reset of axle counters without the application of Aspect Restriction at the end of engineering work (T3, T1A, GSI13, etc))
STR - Special Train Reminder (As for EPR but with slightly different locking, used for the trains that can't be guaranteed to operate axle counters properly)
EPO - Engineering Possession Overlay (A blue shading on the screen used to indicated the extent of engineering work (only applicable when EPR is not used))
SEAs - Standard Engineering Areas (used to apply large sections of EPR and/or EPO and/or Reminders and/or SILs in standard blocks for regular engineering work)
SILs - SPAD Inhibit Longs, used to inhibit the integrated SPAD alarm on signals within engineering work where vehicles legitimately passing signals at danger, or occupation of track sections in the order required to make the alarm believe a vehicle has passed the signal at danger, might cause frequent false alarms and, as well as annoyance, may anaesthetise the signaller to the alarm.

Danny, Does this mean that a seperate display is being provided for this? The current Rugby SCC and Stoke on Trent SCC display this information on both the overview and detail screens and the video wall display as well.
