Stations with split signalling control

[godfreycomplex]

EMR platforms controlled from Three Bridges ROC, unless it's changed in the last year.


Both sides of Victoria (formerly panels 1 for central and 5 for eastern) are now in separate workstations in TBROC.

Whilst we're at it, London Bridge might be a record for having four different workstations control the station (cannon st 1-3, thameslink 4-5, charing cross 6-9 & central 10-15).

All correct (nearest rival is Clapham Junction with 3 in 2 boxes, not counting the yard). If we count non NR signalboxes as well LB is joint top with Waterloo (and possibly Stratford) with 6

Back to West Hampstead now so St Pancras is now controlled by 3 in as many boxes.

I don’t know if it is still the situation, but Aldrington had one platform under Lancing and the other under Three Bridges. There was also a lengthy division round via Margate and also ones either side of Brockenhurst, as well as short ones through Martin Mill, Parkstone, Dunbridge, Porchester and Worplesdon: I don’t know if that is still the same. To a certain extent it doesn’t really matter, so long as anybody involved knows which signal box to contact in an emergency: even if they don’t, the signalman at the ‘wrong’ box would quickly tell the correct man what is what.

Yep, that's why I was querying Reading as posted by @Bald Rick

Something at the back of my mind seems to think the Southern (region not the TOC) platforms (4/5/6) fall under the remit of the TVSC Twyford workstation as opposed to the TVSC Reading Stn workstation. I may be wrong!

Reading is split though when it comes to Electrical Control Rooms (ECR). The AC platforms are controlled by the ECR at TVSC Didcot and the DC platforms (4/5/6) are controlled by Eastleigh ECR.

If we account for the whole Reading area , indeed it is controlled by TVSC but there are two separate signallers managing it - Reading and Reading West .

yes it has changed in the last year

In that case, technically there's 4 workstations involved: Reading Station, Reading West Jn, Twyford (all TVSC) and Reading TCD (GWR).

But we are drifting ever so slightly from the OP's question!

EMR platforms were recontrolled to West Hampstead last Christmas 2023

Surely London Victoria is a prime example?

And therefore Wimbledon.

I could have sworn the DC platforms were controlled from Basingstoke, but evidently not! apologies.

I think it has been considered in various resignalling schemes over the decades but the spur connection to the GWML has always made it too complicated and there's the new low level connection at the East end now joining the relief lines and adding further complexity. I once suggested Wokingham should be transferred onto TVSC so Didcot could talk directly to Guildford rather than having a couple of miles on Basingstoke Feltham workstations in between. The suggestion didn't go down too well at Waterloo!

Slightly different situation at Leominster but I think it technically meets the OP's definition.

The up line through the station is controlled as you would expect by the adjacent Leominster box, but the home signal on the down line is located beyond the station - meaning the down platform is still part of the AB section from Wooferton. In that direction the station limits of Leominster box don't actually include the station itself.

Someone far better informed will know the answer, but I had a feeling that there are parts of the Merseyrail Wirral Line towards East ham/Hooton where Sandhills IECC control one direction and Chester PSB control the opposite line - or something like that.

It was normal at one time for the fringe area between power boxes to have each box controlling only the track for trains approaching it. This was probably intended to give the signallers as much warning as possible to assist in regulating the first junction.

More recent practice is to have the fringe in the same place on both tracks, with a comms link so each signaller can see approaching trains in the other’s area. This is likely to be better in an emergency or for possessions, as the same signaller is responsible for all tracks.

Stirling is controlled by Stirling Middle and Stirling North boxes. Control changes over half way up the platforms

Not quite the case now since the Alloa line reopened with respect to the through platforms. Platforms 6 & 9 are controlled entirely from Stirling Middle. Different signalling systems as well - platforms 2 & 3 are Absolute Block between Stirling Middle and Stirling North, platforms 6 & 9 are Track Circuit Block between Stirling Middle and Longannet (in theory), although as there is very little traffic beyond Alloa, Longannet is now I believe only open as required. Alloa station is within the area controlled by Stirling Middle.

The SAK panel is not the same thing as Stirling Middle. The panel is physically located in the same building as the lever frame but is operationally considered a different location worked by a separate signaller. Similar to other locations listed in this thread where different signaller workstations are co-located under the same roof

Aston SC was (is?) like that, located in Vauxhall Shunting Frame but a box in its own right.

The SAK panel isn't a signal box in its own right though; it's a panel within Stirling Middle signal box. It's correct to say that the Stirling-Alloa line is controlled from the SAK panel, but it's also correct to say that it's controlled from Stirling Middle S.B.

For comparison, you could say that the Larkhall branch is controlled from West of Scotland Signalling Centre or is controlled from the Newton workstation. Both are correct.
