A few years ago, (C-stock) trains from Edgware Road in the morning
peak served Olympia and Wimbledon alternately. There was no D-stock
service at Olympia during these hours. This freeing up of a couple
of D stock trains and the reduced track usage to Wimbledon enabled
a few extra D-stock trains to run back and forth between Wimbledon
and somewhere (Mansion House? Barking?).

Tower Hill.

There is no service from Edgware road to Olympia on this and the
previous timetable at any time of the day.

Thanks. Someone must have thrown the wrong switch somewhere affecting the
display at Bayswater.

The service could have been disrupted, and the controller may have
decided to run one, either to get a train back to time or if Olympia
has had a long interval without a train. I've known Circles to be
reformed into Hammersmith's en route before now
