Old signal boxes in southern UK

[Stellwerker]

Good morning,

I'm a young signalman from Germany interested in all things with old railway infrastructure, e.g. old signal boxes and arm signals, and right on the way for the next holiday in the UK, this time south and west of London, the parts of the kingdom where I have not been yet.

Therefore I'm looking for some places to go, it doesn't matter if there are heritage railways or still in full service. Do you have any recommendations? I'm also looking especially for lever frames of southern origin.

Thanks!

Best regards,
Robert

Semaphore on the mainline in south-east England is now fairly limited - there are corners of Kent (Minster, Canterbuy) and Sussex (Hastings, Bognor Regis, Littlehampton) which retain lever frames and at least some mechnically worked signals.

However I'd suggest a better bet if you want to get to understand the system properly would be reaching out to a heritage railway or museum to ask to visit their signal boxes. the Bluebell Railway in Sussex would be a feast for you, and the St Albans signal box is set up to replicate the mainline feel - a member on here is involved with them but I can't remember their handle right now!

Haslemere on the Portsmouth Direct line has a signal box on the down platform, which was decommissioned a few months ago when the line was re-signalled. It has since become a museum, open limited hours though.

Nice signal boxes at Eastbourne and Lewes - although I don't think they control the signals now.

As ‘southern’ may have different geographical meanings to different people, there are a few manual boxes still operating semaphore signals (the ones with arms) to add. Several boxes in west and central Cornwall, one at Yeovil, one (I think) near Southampton, one on the Isle of Wight, at least one in west London, a fair few around Worcester, some on the routes from Newport to Shrewsbury and (I think) between Peterborough and Ely.

Be aware that signal boxes of all sizes are not open to the general public.

That's me.
We're open on Sunday 9th and Sunday 23rd August, 2 to 5pm or extended opening (UK Heritage Open Days) September 12th/13th 10am to 5pm.

We're easy to reach from SW London as Thameslink run trains through London and we're less than 5 minutes walk from St Albans City station Platform 4 exit.

If any of the above open days don't coincide with your visit to the UK, go to our website, find the contact page and send us a message - we may be able to arrange something for you.

Regards,
John Webb

Princes Risborough North Signal Box is another which is preserved and is opened periodically - it's part of the Chinnor & Princes Risborough Railway, but has its own website https://www.risboroughbox.org.uk/ .

I think you will need to contact them as to when it's open to the public, but I think if approached in advance they might be willing for you to make a special visit, especially as you are a signaller.

The same may be true for other preserved lines (the one that comes to mind not already mentioned, that is well signalled, is the Mid-Hants/Watercress line). You've nothing to lose by asking - the worst they can do is just say no.

Cuxton, Aylesford, Maidstone West, East Farleigh still have operating small signal boxes operating coloured light signals and some level crossings.

Canterbury East and Shepherds Well have disused small signal boxes which are becoming a little derelict but still in situ.

Deal still has working semaphore signals.

Nice signal boxes at Eastbourne and Lewes - although I don't think they control the signals now.

Both closed several years ago. Area controlled from Three Bridges ROC

Bopeep Junction and Robertsbridge SB still in operation

As mentioned the Bluebell Railway have two nice boxes at Horsted Keynes and Kingscote. There is also an enclosed frame at Sheffield Park. I think all of the lever frames are ex-SR. At Sheffield Park, speak to the station staff, and you're likely to be allowed a look in the box. You may have luck at Kingscote, but it's rarer. You might as well try at Horsted Keynes (between trains so when quiet) although I wouldn't get your hopes up.

At Lewes, the box is still standing (out of use though) and you can get a great view of the exterior from the adjacent footbridge. If you're interested in going there tag me in this thread and I can help with directions of how to get there.

The Watercress (Alton- Alresford) and the Swanage both have a couple of boxes - as indeed has the Kent and E Sussex.

At the Spa Valley Railway's Groombridge Station the Signalbox is on the end of the platform. While not a compete scheme, it controls the railway. If not too busy the signalman (historic term used by most heritage railways for any gender) signaller (current mainline gender neutral term) will chat with people let them have a look. It is much harder to see inside Signalboxes on mainline railways

There's an excellent preserved signal box at Romsey, Hants (near to Southampton and close to Romsey station). Guided tour strongly tecommended.

Don't think there are any mechanical signals at Minster now? There are still semaphores at Deal. Canterbury West still retains its fine overhead box, but all signals are colour-light except the shunting signals.

Oh I forgot about Bo-peep. Been past it enough times !

The Kent & East Sussex has signal boxes at Tenterden, Rolvenden, Wittersham Road and Northiam.

Mechanical signals at Minster were abolished over 40 years ago I believe

 

[LittleRedTrain]

The Great Cockcrow Railway in Chertsey is a 7.25" gauge miniature line, but is fully signalled to 'main line' standards and has 3 fully-equipped signal boxes, along with a 'gate box'.

Two use miniature lever frames while the third uses an ex Waterloo & City 'knee frame'
At least one of the boxes gets so busy that only the most skilled signallers can work it 'single-handed'.

Although the signal boxes are not normally open to the public while the service is running, the members are rightly very proud of the setup and I'm sure might be interested to show it off to a fellow professional before trains start running. They operate every Sunday during the summer as well as a regular gala in September.

As a signalling professional yourself, it may be possible to arrange an accompanied official visit to a working mainline signalbox. I would suggest contacting the Network Rail Press & Public Relations Office in the first instance, giving plenty of advance notice. If you are prepared to travel a little further than the London & South West area, the two large signal boxes at Shrewsbury are particularly complex and interesting.... especially Severn Bridge Junction. If you are unable to arrange a visit, try and get hold of a video published about 20 years ago entitled "One Day in Severn". I'm told that not much has changed since then!

 

[Rescars]

I think Haslemere box just been reopened as a signalling museum

 

[AndrewE]

Seeing as Shrewsbury has been mentioned I would offer Exeter West as a huge perfectly-preserved preserved box... except that it's now at the Heritage Centre in Crewe!

Ooops! Sorry!

Possibly stretching the OP's area a little, but Worcester and environs remain quite good semaphore territory I believe. Are there still main line disc signals to be found at work under the Shrub Hill canopy?

 

[Stellwerker]

Good morning!

Thanks for all the advice! We will be around the south coast for two weeks, so there is a lot of time to get around

I'm definitly going to visit one or two heritage railways, there has always been a chance to see their signal boxes. Do you have any suggestions: I would love to see an electro-mechanic power frame, e.g. Westinghouse or another manufacturer.

Thanks!

Best regards,
Robert

The Bluebell Railway in Sussex (probably best to message @SECR 65 for suitable contact details) has a miniature lever Westinghouse type 'L' frame at Kingscote. https://www.bluebell-railway.com/brps/signals/signal-boxes/

 

[AndrewE]

I thought that they were somersault signals, and maybe unique?
p.s. digging deeper, it seems that there are/were both: https://roscalen.com/signals/Worcester/ShrubHill.htm

This is the last of the Shrub Hill 'banjo' disc signals.

They are still there. It all looks complicated but once you know what you're looking at they are easy enough to understand!

The *bang* when the signaller puts the banjo back when the train is at a stand is extremely satisfying, the kind of "old railway" noise that's nearly extinct now.

 

[SECR 65]

Regarding the Bluebell boxes, let me know ASAP if you have a date for when you’re going. I can have a look who is rostered and possibly informally talk to them or advise who would be best to talk to. I won't be able to give any contact details but I can definitely help point you in the right direction.

Sure is! There can never have been many places where a member of the public could experience this, standing directly under a running line semaphore signal which was almost within touching distance. Does such an opportunity exist anywhere else on the network?
