I've noticed "Mind The Gap Between The Train And The Platform" is now
included on the Central Line on-train announcements and I think it's a
different voice. Have yet to discover whether this new 'Sonia' announces
trains terminating at North Acton in the same peculiar manner as her
predecessor.

I think Ms Hammersmith & City is now pronouncing Plaistow with a long
"a" instead of a short "a"
