had a conversation about stations in leaky tunnels the other day. how hard would it to build a station in this tunnel? how much would it cost?

Well, let's assume you want to build a station in a tunnel (perhaps a village on top of a long tunnel or a tunnel under a city or whatever. Most likely, you would go about it by boring a vertical shaft down to the proposed site, followed by a 45-degree shaft for the entrance and exit, sealing the tunnel with concrete from the inside, hollowing out a cavern above the roof, then working downwards on either side, then finally breaking through the tunnel lining from the outside. If that sounds expensive and laborious, it is. Much better just to build a new station at either tunnel mouth.
I'd imagine the clearance in the tunnel would be absolute minimum, and that the tunnel would collapse if any work was attempted to widen it for platforms etc.

They built Conway Park station (Birkenhead) by excavating a tunnel. For details (but not the cost), see
