Trolley Renewal Project


Rebuilding the Trolley System

Trolley Renewal is a $660 million project to rebuild the Orange and Blue Lines. When complete in 2015, new low-floor Trolleys will operate on the entire MTS Trolley network, making trips faster, more comfortable and more convenient for all passengers.

Renovation of five Blue Line stations has been completed and construction is currently ongoing at the E Street, H Street, Palomar Street, Palm Avenue, Iris Avenue, Beyer Boulevard and San Ysidro Stations. Work includes new station platforms, next-arrival electronic signs, shelters, track, switches, overhead electric wire and more.

All stations are open during construction and passengers are directed to temporary platform relocations and substitute bus services. (Please see construction updates below for Park & Ride reduction information.)

To stay in the know, check this page often or use the other options listed in the sidebar.

Frequently Asked Questions

How are riders be affected by the Trolley Renewal project?

MTS is working to minimize the impact on riders, but with station and track closures necessary to complete construction, riders will have to adjust their travels. The majority of the closures and need for bus bridges will happen on the weekend. MTS will supply bus bridges when stations are closed, and will notify riders through station announcements, a telephone hotline, station signage and this website. MTS recommends staying up-to-date on construction closures.

Why do the Trolley Renewal project now?

The rails and equipment on the Blue Line are 30 years old and have far exceeded their original expected use. MTS is beginning the project now in order to avoid delays and breakdowns in the future. Also, the installation of additional rail crossovers between stations will allow MTS to provide service during temporary delays, ensuring smooth riding in the future.

How is the Trolley Renewal project funded?

The funding sources for this project are TransNet II, California Proposition 1B bonds, and the American Reinvestment and Recovery Act. This money comes to MTS designated for capital improvements to the system and cannot be used for day-to-day operations.

Why do we need low-floor Trolley cars?

Low-floor Trolley cars offer a significant advantage over high-floor vehicles. Since the floor of the low-floor cars is level with the station platform, boarding and exit times are reduced for all riders. The low floor also provides enhanced ADA accessibility and eliminates the need for wheelchair lifts.

The new low-floor vehicles are 81 feet in length, which is nine feet shorter than the 11 S-70 low-floor vehicles that MTS currently uses on the Green Line. The shorter length will enable the new vehicles to be used on C Street in Downtown San Diego without blocking intersections. This will allow the Green Line to come downtown, terminating at 12th and Imperial Transit Center and eliminating the need to transfer at the Old Town Transit Center.

When will we see new low-floor Trolley cars?

The new low-floor vehicles began running on the Green Line on Monday, October 3, 2011! The Green Line is now completely running the new low-floor Trolley cars. Low-floor cars are scheduled to begin operating on the Orange Line in January 2013, and on the Blue Line in 2014. These dates may change due to construction schedules.
