Seconded. Possibly facilitated by new main line underground section from say Bathampton, new station under Bath, new station somewhere underground just north of Temple Meads with links up to the current station and somewhere closer to the city and connecting to an upgraded Severn Tunnel with more capacity and upgraded relief line to Newport and Cardiff. Doesn’t have to be particularly high speed due to stops, but frees up existing surface capacity for more local services including something lighter and cheaper which could also go on-street in places. Given a huge chunk of underground railway costs are for stations, only build a couple of them for key heavy rail stations and divert them rather than a whole new underground metro system, as has been frequently mooted.A VAL or similar light metro for Bristol
