Just worked it out there with the current timings that the PVR on a:
- 20 minute frequency from Durham to Newcastle
- 10 minute frequency from Chester Le Street to Newcastle
Would stand at 13 vehicles with the following layovers:
- 12 minutes in Durham
- 7 minutes turnaround for the short 21 workings to Chester Le Street
- 7 minutes turn around at Eldon Square
Which I believe is the same if not, very similar to now. If GNE however decided to relax the timings, then the PVR would be 14 vehicles meaning a spare B5LH would still be available.
Who knows but the only thing I can think off given the extra resources as well as the new Streetdecks on the X21, is that GNE would want to encourage people to use the X21 over the 21 to help ease pressure further particularly if travelling anywhere between Durham and Chester Le Street to Low Fell, Gateshead and Newcastle.
Not saying the 21 is going to be reduced mind but it could be a possibility.
