I observed the New Orleans streetcar system. As a former NJT bus driver I am still in confusion of the schedule. They'll have four running together in the course of two blocks, then none for forty minutes.
Classic transportation system, efficiant for shuttling tourists down to the French Quarter. If you want to get to work on time I recomend the bus system.
Although I hear they aren't much better. I asked Waffle if the Streetcars run 24/7. He said he has seen them at 4:00 AM in the morning, howerever it may have been the 11:00 PM streetcar finishing.
