Tesla has finished construction of its Loop under the Las Vegas Convention Center and has started to test the system.

The system is known as the LCVV Loop and consists of two 0.8-mile tunnels and three stations. Two of these stations are located at either end of the convention center while the third is located underground in the middle of the Loop.

The system operates exactly as you would expect. There are a bunch of Tesla Model 3, Model Y, and Model X vehicles that are driven (by drivers, not their autonomous driving systems) through the Loop, carrying up to four passengers at a time. Those taking a ride simply jump in an out of the cars at any of the three stops.

The Boring Company claims that the system can reduce a 45-minute walk from one end of the convention center to the other down to a two-minute ride. During testing, many passengers had to wait a few minutes to catch a ride, however, and there was also some congestion in the central station.

Elon Musk’s company claims that the system can transport up to 4,400 people per hour through the tunnels but according to TechCrunch, the real number could be closer to 1,200 people per hour. The Las Vegas Convention Center had considered constructing a more traditional light rail system that could shuttle hundreds of people per train but ultimately settled for The Boring Company’s Loop as it was considerably cheaper, costing $52.5 million.
