I've been wracking my ever-decreasing brain cells and there is a Platform 0 at Doncaster, I recall it's quite a walk from the platform to the rest of the station, but arguably the next platform is No 1 where many of the LNER London Kings Cross departures. are from.
On our joined up public sector railway, we…
…cut the long established Sheffield -Doncaster - Scunthorpe service into a Sheffield - Doncaster one and a Doncaster - Scunthorpe one, to avoid running so many short DMUs over the flat ECML at Doncaster and free up more paths for longer distance services…
…spent lots of money on Platform 0 so that the Scunthorpe trains were pretty much operationally independent of other services at Doncaster…
…cut the hourly Doncaster - Scunthorpe service back to a replacement bus service every two or three hours (which AIUI still hasn’t returned to any rail provision, despite other routes returning towards normal as the rest of the country recovers from Covid)…
…at least Platform 0 gets used by the hourly Hull stopper (well, it was an hourly Hull stopper, it’s currently got gaps of a couple of hours and many services no longer run beyond Goole…), so it’s not totally wasted money but the investment in infrastructure at Doncaster, and subsequent cuts to the services that justified that investment by our enlightened public sector Operator Of Last Resort is a great example of government waste/ right hand not knowing what the left hand was doing/ Unlucky coincidences, depending on where you are on the political spectrum!
