Is there a set capacity of bay platforms of stations.
Basically was wondering how many trains platform 1&2 at leeds could take per hour. Im taking this as ignoring trackwork outside station and just treating as 1 line going into 2 bay platforms as an example.

Rules of the Plan (Network Rail) should give you what you need for a specific location - minimum turnarounds (which can vary widely even at a single location, depending upon factors such as stock type and the distance travelled by the arriving service) and platform reoccupation time (which will be affected by the track and signalling layout). So no, there's no single figure that fits everywhere!

I've read that Charing Cross has about the highest practical utilisation of bay platforms on the mainline, 29 or 30 tph over 6 bays, so approx 5 tph (10 movements) each.

4 tph each might be more typical, so a reasonable generalisation could be found by checking a few busy terminus stations (for example Fenchurch St, Cannon St etc.) on opentraintimes for the peak period?

Of course LU have much quicker turnrounds in a pair of bays at places like Brixton and Elephant and Castle, but pretty specialised signalling to allow for very accurate train speed and position detection.

Fenchurch St gets 21 an hour in the high peak off 4, but the gold medal goes to Moorgate GN with 12 off 2. I think.

Signalling and the provision for permissive platform working will probably be one of the main factors judging capacity.

London Underground terminus platforms have a quick turnround time (about 2 minutes during the peaks) because as soon as a train arrives there will be a driver waiting on the platform ready for the return working.

Going slightly OT, that reminds me of Liverpool Central Low Level before the loop was built in 1971 when they handled 24 terminating tph in 2 platforms during the peaks, but they weren't terminal platforms. When a train arrived in the arrival platform, a driver got in the rear cab to shunt the train into the turnback to bring it back to the departure platform to work it back. All this was controlled by a totally automatic signalling system dating from the 1920s with LU style trip cocks. There's nothing new...

On most lines, yes... and only in the peaks!

That is impressive thinking about it, yes. Although don't know if the signalling is to LU standards given the history of the Northern City Line :)

I think it might be a mix- British Rail standard colour light signals, but with Underground style Tripcock protection.

It also depends on the variety of trains. Say if you focused 1 and the proposed 0 on Harrogate line services, it is likely to be able to be set up on a fixed frequency.

The problem with 1, 2 and 3 is that they all focus on to a single section of line, along with 4 and 5 being able to use it too, so that will have a significant impact on capacity.

It is national rail standard signalling with added tripcock protection. The tripcocks go when ETCS is installed in 2018, and there may well be a capacity increase as well.
