By the standards of some German cities (smaller ones, usually) Castlefield is sort of an S-Bahn, not all of them are Merseyrail like segregated systems. But I do agree, Manchester is more than justifying of a proper underground, and I wonder if it might get one at some point in the form of a Den Haag style tram tunnel.
Yes an adaptation of an underground tram tunnel is what is most likely, but this is where tram-trains come in to the mix. Yes, I know some people on this forum hate the idea of anything other than heavy rail, but local heavy rail has been failing Greater Manchester for decades, while Metrolink has been a much greater success. The proposal for a Piccadilly-Cornbrook tunnel (with I assume at least two intermediate stations) is what will facilitate this. In fact it might be more train-like than tram-like, if services are confined to Altrincham & Warrington services from the west and onwards to Glossop & Marple in the east.
