This isn't a quiz question because I don't know the answer.

Saw this in the four foot on the down line immediately after the Royal Albert Bridge and wondered what it was.

Looks like a portable AWS▸ (Automatic Warning System) magnet to me.  Used for TSR▸ (Temporary Speed Restriction)'s and ESR▸ (Emergency Speed Restriction )'s.  Here's one of them from the catalogue:

Thanks II - that would make sense.  Looking off the end of the platform as the line curves round towards Liskeard I could see a flashing emergency warning board as shown in one of the pictures below the main one in your link.

Would go with portable AWS▸ (Automatic Warning System) magnet, rather than SDO▸ (Selective Door Opening).

Must be a fairly modern one I thought they were bigger and fitted over the sleepers rather than clipped to the rail.

II is correct.  Its a portable AWS▸ (Automatic Warning System) magnet used for TSRs▸ (Temporary Speed Restriction) and ESRs▸ (Emergency Speed Restriction ).
