I recently read that the 1972, 1973 and 1992 tube stocks have to have PRM TSI specifications installed in order to keep them beyond 2020 what do you know about this?

I'm not sure what those initials stand for but 1972 Stock are to have wheelchair spaces and backboards fitted.
1992 Stock are to have similar work, with internal customer information screens, LED lighting, wheelchair spaces fitted all in the new workshop to be built at Acton.

That would be RVAR, not PRM-TSI.

And yes, 72TS and 92TS are to be worked on in Acton.

But London Underground isn't an Interoperable System, so RVAR (Rail Vehicle Accessibility (Non Interoperable Systems) Regulations) apply.
