Question

How many volts are used for a uk 3rd rail electric train/locomotive?

Answer 1

enuff to kill you .

Answer 2

It depends where you are.  London Underground is 630V to 660V.  The mainline railways in Southern England were originally also 660V but most are now 750V though the line from Farnborough to Bournemouth is 850V.  The line from Euston to Watford is 660V.  The lines on Merseyside are 750V.

Answer 3

"The Underground is one of the few railways electrified by the four-rail system. In addition to the two running rails there are two rails that supply power to the trains, one outside the running rails electrified at +420 V DC, the other in the middle at -210 V, producing an overall traction supply voltage of 630 V."

Answer 4

A nominal voltage of 750V DC - though this can vary locally - EG the Euston to Watford, Putney to Wimbledon and Richmond to Acton lines are 650V to allow London Underground trains to share the lines

Answered above and more than enough to fry you!
