David J. Hayes says: Based on WTT information for the Birmingham area, this could be the 10:47 SuO service from Carlisle to Euston, which was booked to run from Stafford to Rugby via Bescot and the Aston-Stechford-Coventry axis. It, therefore, didn't call at Birmingham nor did it call at Stafford, Wolverhampton, Coventry or Rugby. It's possible that during the rest of the week 1A22 traversed the Trent Valley section of the WCML between Stafford and Rugby; i.e. via Lichfield, Tamworth and Nuneaton.
