I think that there are constrained from getting much more frequent on
the Wimbledon to Sutton bit, due to the single platform. From memory,
services are approximately every 30 minutes around the loop in each
direction (even during the peak hours), giving 4 trains per hour
through the single platform. I suppose that the frequency could be
increased, but probably not to much more than every 15 minutes in each
direction without affecting reliability and pathing.

However (and I don't know if this is planned), there is the
terminating track at the north end of the platform where the Tramlink
platform is. This would allow a greater frequency on the Wimbledon -
Tooting - Thameslink route. There are a couple of trains that use this
already during the peak shoulders.

Now that the South London RUS is out - I see Wimbledon loop trains will be
terminating in the bays at Blackfriars in the final Thameslink arrangement,
avoiding the crossing moves south of Blackfriars that we have discussed in
the past. There seems no real reason why the service might not be
transferred to Southern (or LO) then, using DC stock, leaving FCC or their
successor to concentrate on the main routes?
