This Article introduces a new proposal for a tram/monorail system. It uses an elevated monorail and old 747 airplane bodies to achieve a small footprint and efficient operation. I am only writing this because after I read the following
"Fixed routes and tracks means that there’s little to no crossing traffic and high speeds can be maintained (estimated at between 100 and 200 miles per hour average speeds)."
The first thing I thought was...I hope it has a large windshield washer tank to get all those dead bugs off the front. :)
