Shuttle-Loop Transit

Definition
A Shuttle-Loop Transit (SLT) system is

"the simplest type of AGT system. Vehicles move along fixed paths with few or no switches, The vehicles of a simple shuttle system move back and forth on a single guideway, the horizontal equivalent of an automatic elevator. They may or may not make intermediate stops. Vehicles in a loop system move around a closed path, stopping at any number of stations. In both shuttle and loop systems, the vehicles may vary considerably in size and may travel singly or coupled together in trains."
