Can anyone help on the web I saw a photo which had a plate fitted which had TSB1448 on it, I assume the number relates to the location but what does TSB stand for?

I have been looking for the photo but can't find it but here is another one TSB144B

Clearly TSB144B is the bridge designation, all bridges over or under LUL lines have a bridge designation. However, the actual designations are still something of a mystery to me. Looking at the bridge databases supplied to one requester under the FOI gives an incomplete list of bridges under JNP, BCV, SSL and DLR perhaps because he was interested only in road/rail/river crossings or possibly because the lists were sanitised. For example I cannot find bridge MR99A in the SSL list, yet it is a bridge known to me as I installed the magneto telephones at each end which were/are direct lines to the signal cabin such that those wishing to cross the bridge to/from platform and sidings could ascertain whether or not it was safe to do so. Of course the bridge may have been redsignated. While one might suspect that all Met railway bridges are designated MR it is simply not so, e.g. on the Watford branch the bridges are MLNE, elsewhere they are single letter numbered designations. No doubt someone from the Civil engineering department such as the old 'Bridge Engineers' section who dealt with such structures would know or be able to discover the history of the bridge designations, some of which appear to be obvious and others which do not.
As for TSB144B it is probably safe to assume that 144B is the actual bridge number and that TSB is the type of bridge where T probably is for Tunnel, S probably is for Subway and B may be for Bakerloo although it could simply be Bridge. There are many tunnel subway bridges in disused or otherwise non-public areas of the tube railway lines.
The only way to know for certain how the ID plate relates to a location is to see the full bridges databases but I doubt such info would be available to anyone other than someone employed in the civil engineering area of LUL.

RT thanks I was thinking along the lines of what you said T for Tunnel B for bridge S for subway but I don't think so after trying to find what I saw before which still remains to be done, however, I looked on one of the Urban Exploring sites and found another photo with the same details but it is not a bridge well I don't think so looks like a larger tunnel. You will see that someone in the photo does not wish to be identified.

I think your lost picture is here:- TSB148BThe ID plate will exist to indicate the location of the structure and in the case of an overbridge or underbridge will be seen both on the bridge and above or below it. The picture you show with the masked explorer is no doubt the same location and the bridge may well be above his head where the girderwork over the tunnel can be seen. These bridges all appear in the JNP bridges database that was released under the FOI request. TSB84A BRIDGE - UNDERLINE WATERLOO STATION TSB84B BRIDGE - UNDERLINE WATERLOO STATION TSB84C BRIDGE - UNDERLINE WATERLOO STATION TSB118A BRIDGE - UNDERLINE OVAL STATION TSB118B BRIDGE - UNDERLINE OVAL STATION TSB166A BRIDGE - UNDERLINE CAMDEN TOWN STATION TSB166B BRIDGE - UNDERLINE CAMDEN TOWN STATION TSB166C BRIDGE - UNDERLINE CAMDEN TOWN STATION TSB168C BRIDGE - UNDERLINE KENTISH TOWN STATION TSB168D BRIDGE - UNDERLINE KENTISH TOWN STATION TSB128A BRIDGE - UNDERLINE LEICESTER SQUARE STATION TSB208B BRIDGE - UNDERLINE HYDE PARK CORNER STATION TSB222B BRIDGE - UNDERLINE RUSSELL SQUARE STATION TSB222E BRIDGE - UNDERLINE RUSSELL SQUARE STATION TSB227C BRIDGE - UNDERLINE HOLLOWAY ROAD STATION TSB227D BRIDGE - UNDERLINE HOLLOWAY ROAD STATION

Although it's hard to tell properly from the photos, the second photo appears to have been taken with platform area in the foreground (taken by standing on the track) with the opposite running line in the background through the crosspassage. The first photo shows the passenger bridge over one of the running lines (as seen by the half moon steel plates either side).
I presume that the plastic pipe going through the bridge side in photo 1 is the same pipe that appears to the left of the person in photo 2 and that the girder in the top left corner of photo 2 is the support for one side of the bridge. The concrete steps lead down to track level and would have been an addition at some point. The top of the stairs and the crosspassage floor being at platform level (if a platform had been built). I assume that there is an exit to the left at the centre of the passage with a stairway leading up. Turn left at the top of the stairs to cross the platform in photo 2 and then walk along the bridge in photo 1 to the exit (probably lifts / stairs)
The unfinished state of the station etc. walls looks as if it was a station that was built and never opened. Therefore, I suspect that this might be Bull & Bush.

I should have googled before posting The location is indeed Bull & Bush as photos on this site shows: [ Click here ]The top photo shows the same platform (which I'm certain is the SB platform) with the steps in foreground. A stairway leads to the right (not left as I first thought) of the crosspassage and up towards a second overbridge (TSB148A?) which can be clearly seen halfway down the platform. There are more photos and a diagram on the Subterranea Btitanica site: [ Click here ]

Nortube it was not where the location was rather what TSB stands for although in this case it is Bull & Bush station although now thinking what are all those pipes for as you don't see them at working stations.

Somewhere while looking into this I saw a comment about the unusual staircase to street level. It's not unusual at all, it is typical of an emergency detraining location such as found on the Central and Victoria lines and elsewhere.

I haven't taken a detailed look at the pipes but generally such places have various water, sewage, drainage and ventilation pipes which would not be usually be visible at stations in use and which in some cases will not exist.

I think it was an official visit, SB have built a good reputation for getting organised access to such locations, I would not see them risking that with a UE visit although I'm fairly sure that SB began that way long ago !

RT thanks I suppose it was all down to what use was being made of the station. I am sure that I have seen a Central line location on one of those sites.
