Technically, Birmingham - Crewe via Stoke, and Birmingham - Rugeley are West Midlands services. Perhaps the 323s could be used on those? Maybe nine units are not enough though.Sorry if bit off topic but from what I last seen believe from December they will route the Crewe to Birmingham round the Darlaston way but call at Tame Bridge Parkway before the new stations open by 2022. Would make sense the 323s being kept for the local services between Wolverhampton, Walsall and New Street. Would save the messy arrangement currently whereby we have LNWR units operating West Midlands Railway services.
