I’ve never seen anything quite like it before, but it appears to connect into the troughing, so my semi-educated guess would be some sort of power supply point.

It could just be a cable termination box, where they join equipment tails to a longer main run. Could do with a photo from the front really.

The folks over on the UK S&T Group on Facebook reckon it’s to do with the GSM radio system.

That rings a bell. I think there was a discussion of this before in one of the various NW electrification threads, it’s where there’s a directional GSM aerial to fill in through a problem area such as a tunnel (or anything like that). Unfortunately I can’t find a suitable search word to find the discussion at the moment...

That’s pretty much what the folks have been telling me.

The picture was taken in July when my husband and I were out on a walk. Unfortunately this is the only picture of it that I took.

Apologies for the stupid question but what does GSM mean? If it makes any difference there is also a signal in the 'Up' direction which appears to be a replacement for the banner repeater signal which once existed on the same spot.

Not a stupid question at all! Now, if you want a stupid answer, I can help. I think it’s Global System for Mobile Communications.

Global system for mobile communications (strictly it should be GSM-R, where the R means Railway). It's the latest thing in signaller <-> driver communications; basically a special mobile phone network.

Many thanks to both of you for the explanation.

Yep. If you have a mobile phone then you have been using GSM for years*
Network Rail basically built their own mobile phone network which is for internal use. British Rail basically did the same thing years ago with a traditional cable phone network.
*unless you live in Japan or parts of America where they use CDMA, which is pretty similar technology but doesn't use a SIM card.

Just for interest, I found the picture of the other (far more informative!) side of one of these things:
