Why on the Piccadilly as it does not come into contact with National Rail

Slightly changing the subject, LT drivers alsomo have to know how to read
national rail signals as well, don't they?

Yes. On the Bakerloo and District lines.

Control staff on the District, Piccadilly, Metropolitan and Circle
lines also need to know too.

I should have mentioned that the signal operators west of Tower Hill
are Piccadilly line ones.
