Likely to just be engineering alterations, the times (past the hour)
have also changed, there is also a reduction in some of the calls
(Southall loses one of its two stops per hour) of the Reading trains
after 12th September and retiming of some of the fast services. It
will be interesting to see if the Connect trains resume in the
December timetable.

I've just read elsewhere that whatever the works are for, Slough to
Paddington is down to 2 tracks on Sundays for the duration...
