I do not recall seeing this mentioned in this learned forum so here goes.
There is a tube railway to Elstree in existence, it was built this century, from St.Johns Wood.
At least, if you consider the German Wuppertal Schwebebahn (the 'danglebahn') as a railway, then this St.Johns Wood to Elstree counts as a railway, because it has a similar suspended monorail in it.
A £70m 20 km National Grid 400 kV AC, 1600 MVA capacity ~3 m diameter cable tunnel was constructed between 04/2001 and 02/2004, completed in 11/2005 and it has a railway, an overhead monorail. Murphy built the tunnel and FATA supplied the 'trains' (... and for the tunnels prime function, ABB the high voltage gubbins).
The 4 remote controlled battery vehicles operate up to 2.5 m/s from an I-beam fixed to tunnel crown; vehicle and trailer can carry up to 5 personnel and 500 kg load for up to 20 km without recharge. FATA Automation are not a rolling stock builder as such but a specialist in materials and factory production line handling.
There are various web links with a lot more details :

I knew of this tunnel when it was being fitted out, then when Crossrail tunnel contracts were awarded it was mentioned in one of the contractors references, but then I had no gen on the trains. What reminded me to look again in the past week or so was the HS2 project includes a map where the cable tunnel is marked :
assets.hs2.org.uk/sites/default/files/pdf/es_maps_docs/C221-MMD-CV-DPP-010-201100.pdf
References also to similar tunnel and vehicles between Beddington and Rowdown but I've not found much about that one yet.
Hope this interests someone here, and that I've posted it in the right section.
