The San Diego Metropolitan Transit System (MTS) is the public transit agency that serves the city of San Diego, California. It operates a network of buses, trolleys, and light rail trains, including the San Diego Trolley, which is the second-largest light rail system in California.
The MTS is currently undergoing a trolley renewal program to refurbish and replace its aging trolley vehicles. The program began in 2014 and is expected to continue through 2022. It involves removing old trolley vehicles from service, repairing or replacing worn-out parts, and installing new technology and equipment.
The trolley renewal program is being funded through a combination of local and federal funding, including a $1.6 billion grant from the Federal Transit Administration. The goal of the program is to improve the safety, reliability, and efficiency of the San Diego Trolley system and provide better service to passengers.
