Whats wrong with providing uninterruptable power to the bits that need
resetting so if there is a power cut / surge in future the only effect
will be a loss of traction?

Cost/benefit ratios.

If it only happens once a year, how much is it worth? Given that you
will need perhaps dozens or hundreds of UPSes. And if they fail more
often than the main power feed, you're actually on a loser!

Especially, when you consider that this is the only time since I joined LU
in 1985 that this has happened. (Twice if you count the "London-wide" power
cut). The cost of maintaining UPS on the signal main alone would be
astronomical, let alone traction, lifts, OPO kit, station lighting,
escalators et-al...
