FCC drivers are currently training on dual voltage 377s, a number of which
will be transferred from Southern.

I wonder how much the SER Blackfriars pax will like 319s in lieu of
their, er...beloved (!) Notworkers. In addition, there will be some who
get to travel in 377s if their service starts/terminates at Gillingham
