The main electric freight loco is the class 90. Class 92s are little used.

You sure about that? I thought the 90 was a passenger loco that only
occasionally did light freight because its built for high speed, not pulling
power.

When did you last see a class 92 hauling anything? Most electric freight
are hauled by class 90s.

Class 92s tend to be seen with Channel Tunnel traffic, there is no
current reason for them to be preferred over straight 25kV locos away
from such traffic.

There is no sense putting in new 3rd rail between two 25kV areas; it
is obsolete, requires more substations and wastes more energy.
