You would either have to build an elevated track or build over passes where ever the rail line crossed a road which would drastically increase the price of the project. It would more than likely be less expensive than a monorail but it all comes back to the same thing....return on investment. A light rail system also has all of the same problems that the monorail has.
Thank you Master Yoda, I mentioned earlier this basic statement yet the OP either missed it or chose to ignore it
