The line features low floor streetcars. Riders in wheelchair or other mobility device can board through any of the two center doors. Push the blue button on the train door to open the door and deploy the boarding ramp.
The line operates as a single track line with a passing track at the 500 E station, where the two trains meet to pass, and at the Sugarhouse station. The line uses the same S-70 model rail car as on TRAX, except that S-line cars operate as single cars with couplers covered up. The maximum speed is reduced from 65 mph to 25 mph.
The corridor features Parley's Trail, which will eventually stretch 8.25 miles from the Jordan River Parkway in the west to the Bonneville Shoreline trail at I-215/I-80 in the east. The segment between Central Pointe and Sugarhouse is known together as the S Line Greenway.
