Yes, there are tunnels, but these are just the underfloor heating/service tunnels common to most hospitals. One branch does in fact link with the Universities engineering department - something to do with the steam turbine once connecting to the hospital boiler room I think. The tunnels are still there, but I've not been down them. The boiler house is now stripped out.
