What is it?

Some profile of weird railway track,too big for o/h crane,maybe ground crane?
It’s stacked in a field by a friends house.

I would say flush mounting rail track,as the trams have.

Definitely looks like the bottom of it has been buried in the ground.

Tram rail.

As @dan.taylor.1 said. The rail is covered in rubber and set in concrete in a "trough" below ground level with the top face flush with the road surface so that vehicles can pass over it. Spent quite a while last year on the night shift replacing the rails on the tram system in Sheffield and it's truly awful stuff to deal with. The contractors dig it out and cut it into 40' lengths then load it onto a flatbed artic trailer for scrap but there's big lumps of concrete and rubber hanging from it, not the best load to carry...

Used to take it to Ron Hull's scarpyard in Rotherham where it was always a treat watching the guy with the grab machine pick each piece off as delicately as you like.

And it's shaped for the single flange tram wheels to run on and in. A normal train wheel flange overhangs the top of the rail but the tram wheel flange runs in the "cup" while the tread runs on the top face.

It’s a trap for push bikes

Tram rail.

Looks like the track they used to concrete flush in the floor for those industrial sliding/concertina garage doors.

looks like the recessed wagon tracks found in the stone quarries under Bath.
Used when the wagons were hauled up and down inclines.
