Some other observations:
TfW set goals of not only having 3tph between Chester and the Junction (calling at Colwyn, Rhyl, Prestatyn and Flint minimum), but also of speeding up at least 12tpd running Bangor to Chester in no more than 1hr 5mins.
The current timing for an ATW 175 train from BNG to CTR calling only at LLJ, CWB, RHL, PRT and FLN (the 17:19) is 1hr 8min. Virgin's Voyagers do the same run in 1hr 7min. To get under the 1hr 5 min barrier on current timings you have to drop more stops (viz. 14:25, 16:26 departures), but then they won't count toward the above 3tph target. These seem mutually exclusive to me.
Rhyl to shotton (very nearly) is all 90mph now, so that will easily claw them 3 minutes in. No point looking at today’s timings as the line is full of TSRs keeping the old speed in place. Very annoying.
