Identifying where a OHL stantion is?

[Ladder23]

Hi guys with a photo I’ve seen I am trying to work out where the location is, the stantion displays the following

BB
13
26

I am told BB is the route, 13 is the mileage and 26 is the post number in that mile? I work on S&T so I ain’t familiar and the person who told me wasn’t 100% sure.

All help is appreciated thank you

A diagram of the route codes can be found at http://www.railwaycodes.org.uk/electrification/ole_schematic.pdf

They are not unique, so BB could be any of Braintree branch, Balloch branch, or Birmingham New St - Wolverhampton. However the first two don't have a milepost 13, so it appears your photo was likely taken somewhere just north of Wolverhampton station.

Fantastic that’s a great response.. Birmingham would make sense as the photo shows a class 350 in LNW livery, so it would be on the WCML somewhere!

On installations since the 1970s, the "mileage" is actually kilometres. Though that wouldn't apply to Birmingham-Wolves.

Does every stanchion have an ID plate?

Yes, each structure does.

Yes, each structure does.

Some ones have a "plate" in the form of a strip of sticky-back plastic (mainly installations from the 1970s) - these are gradually being replaced by metal ones.

That map also seems to show "BB" as "Bletchley - Oxford", although that may of course change...

A tiny bit at the Bletchley end is/was already wired with BB masts. As you say, though, as and when the full route is wired, it could well have a different code. Current conventions suggest it may become OXD (but even then, conventions change).

BB 13 41 is the first stanchion on the main line north of Wolverhampton North Junction, so the one you're trying to identify would be between that junction and Wolverhampton station. Likely where the railway crosses the canal.

Perfect that would make sense! Thanks so much

Each structure does indeed have an ID, but the plate is sometimes missing.

I believe that the main radial lines out of London were originally going to be lettered anti-clock wise around London starting and ending at the Thames, hence why the MML is F and the WCML is G. (Other lesser OHL fitted non LMR routes exist)
