This is sudden and unnanounced switching of platforms is a CONTINUAL
PROBLEM at H&H and also Ealing Stations. Complaints to FGW etc. remain
ignored. CJB.

Crikey, they're still doing that? I haven't used that station
regularly for about 4 years.

The last time that happened to me the station staff were laughing at
the people rushing across the footbridge. They'd made an
incomprehensible announcement over the PA at the same time as the
automated change of platform announcement kicked in, so thought it was
funny that everyone had ignored them.

H&H has serious problems with staff being unable to communicate in
English, if they bother to communicate at all.
