There is a connection both east/northbound and west/southbound between
the Picc and Victoria lines for engineers trains. As the signalling
systems are so different from each other (the Victoria is automatic),
it would not be possible to run 73 stock on the Vic. or 67 stock on the
Picc. other than under a total possession.

67 stock can be fitted with tripcocks; somewhere I have the exact rules
for trains moving between the two lines and cutting various bits of kit
in and out.
