As for the Victoria Line stock, it hasn't had to deal with the
horrible bends that exist on the Bakerloo either, so it's probably in
a better condition than a lot of stock.

Victoria Line stock utilisation is much higher than Bakerloo.

The current SX service is 38/27 peak/off-peak trains with 16286 km
training running timetabled each day. Current Bakerloo is 33/29 peak/
off peak but running only 10541 km.

1967 stock is accumulating mileage and therefore approaching its
fatigue limit at a rate 33% higher than 1972 stock = a 1967 car does
in 3 years what a 1972 car does in 4.
