I know its a hijack, but how about just expanding the bus service?

Why do some people have this fetish with train lines? They take forever to build, almost never result into positive RoI and you have this problem of how to get to/from train station to where you need to go.

Buses on the other hand can go anywhere, do not need huge infrastructure build-out, can be expanded/updated in the direction of real demand, much cheaper to run and possibly do not have as negative RoI as the trains/trolley…
