Oh really. Boston MBTA green line is a subway line that extends onto
surface streets. Not full rail gauge iirc (though other lines are) and
neither surface or tunnel curves could handle freight cars. The surface
trolley portions that run down boulevard median are direct line extensions
of the tunnel line but do have grade crossings at boulevard stoplights.
