Vegas is building the largest monorail transit system in the country:
Plans call for the line to stretch up to seven miles by the time construction ends later this decade, with stops at most casinos, downtown and the local convention center. Sleek bullet-shaped trains will be run by computers, not drivers, and travel up to 50 miles per hour on a winding route above roadways.
There will also be unusual safeguards. Since more than a few riders here are bound to be sloshed by more than a few drinks, every stop will be walled and sealed in glass, with doors timed to open only at the moment trains arrive — so no one in a stupor falls from a platform.
