The current "white space" between Wrexham North and Saltney Jnc means any soutbound additional trains over this route will have to tail chase the existing HHD/CDF or HHD BHI ATW services.
Or could the HHD-BHI service tail the Gerallt Gymro?
Forgive the continued amateur theorising, the following is only based on looking at the public timetables (ATW booklets 1 and 4).
The 0520 Shrewsbury to Chester is the first public train timetabled to run through Wrexham, departing WRX at 0604 and arriving at CTR 0625. In the meantime, the 0425 Holyhead to Cardiff leaves CTR at 0620 and arrives at WRX at 0638. I assume from this that a southbound service can leave CTR 5 minutes before a northbound is due to arrive, passing between CTR and Saltney Jn.
On that evidence, given that the next WRX-CTR service arrives at CTR at 0716 (the Virgin service to Euston) a southbound service could leave CTR at 0711 (with the Holyhead-Birmingham service, currently leaving CTR at 0722, tailing the express). A stopping service takes 61 minutes to travel from CTR to Shrewsbury, at which rate the express would get to SHR by 0812, 3 minutes behind its current timing.
The HHD-BHI service currently stands at Shrewsbury for 10 minutes, so could leave CTR a bit later and still get to its path for Birmingham.
