Is there an intention to add any more diagrams in the coming weeks, or will it remain as just the two for the foreseeable?
Two for the foreseeable. I believe TPE haven't accepted anymore yet as CAF have not delivered a product that is up to standard.
I'd guess that the key development needed for more diagrams is enough staff trained at Scarborough to start and finish a diagram there instead of Longsight.
I think that’s spot on. With the new Scarborough TMD now open and Scarborough crews being trained, it seems things are moving on very nicely.
It isn't obvious that any more diagrams would be easy to add before the December timetable change so perhaps just two until then? Looking at RTT:
1) There aren't any additional workings which start at Longsight shown before 16 December 2019. One of the current 185 workings to Scarborough starts at Ardwick and two which start at Scarborough finish there.
2) There are three 185 diagrams that start at Scarborough. One (0600 to Manchester Airport) goes onto Newcastle / Middlesbrough workings. The other two do Scarborough all day but end up at Ardwick as noted above
3) There are three 185 diagrams which end at Scarborough. Two do Newcastle / Middlesbrough workings during the day, the other starts at York.
4) Other diagrams start at York which doesn't seem to get 68+Mk5 stabled until mid-February
The closest to an out and back diagram from Scarborough onto which you could put 68+Mk5 is the diagram which starts with 0738 Scarborough to Liverpool Lime Street. This ends 2146 Scarborough to Manchester Victoria / 2358 Manchester Victoria to Ardwick. You could run this last part by stepping up the 185 off the 1856 Liverpool Lime Street to Scarborough (arrives 2139). It would then be straightforward to swap the 68+Mk5 which does the 2246 to Manchester Piccadilly to create three diagrams (with the existing pair).
Having looked at RTT after 17 December, there are then additional workings from Longsight and segregation of Scarborough workings from other routes. Notably, the current Manchester Victoria starter (1F48) goes back to coming from Ardwick until 17 February 2020. It would appear that this date is when 68+Mk5 stock is planned to start / finish at York and maybe from which point there are seven diagrams but obviously I am only guessing at this.
For reference, I think the current weekday diagrams involving Scarborough implied by RTT are:
