Ah, interesting.
Well, if we used low floor trolley buses, you would only need a very low platform to bring people to floor height. Ventilation improvements could probably be wrought with some fans on the existing ventilation shafts, and you would of course put in lighting and such. Stations in the covered area could be made by digging down and making room for a stairwell and elevator for each direction at each station. The line would terminate with a loop at the eastern extremity of the covered section. Cannot go farther since someone built a parking garage in the way across 21st street. You could build a ramp and go down pennsylvania ave to callowhill, then wherever you want to go ( i thought convention center was a good idea).
