A progress report for October.

We continue to build a better T. At the center of our plan is a commitment to a reliable, more resilient, faster and safer system. We have finished our accelerated improvements on the Orange Line and are now focusing our resources on the Red Line, following our long-range plan. As work continues and progress is achieved, we will continue to provide monthly updates like this one. ORANGE LINE Track replacement, station updates, tunnel work, and improvements.

In October, crews replaced 1,330 feet of track, installed 8,000 feet of fiber-optic cables for signals, and overhauled 45 fare gates. Tunnel leaks were repaired. We cleaned and painted the stations at Chinatown, Downtown Crossing, State Street, and Haymarket.

RED LINE Replaced track, rebuilt railbed, updated elevators and stations.

In October, we replaced 4,282 feet of rail, 1,280 wooden ties, and rebuilt the track bed with 1,320 tons of ballast. Crews also accelerated the return to service of the Harvard Station elevator, including construction of the elevator head house and mezzanine elevator lobby. Substantial work was also completed at Park Street Station, where we enhanced lighting, replaced stair treads, and painted.

COMMUTER RAIL Safety improvements.

Crews installed Automatic Train Control (ATC) equipment on the Needham and Franklin Lines, nearly 26.5 miles of track in total. ATC is an upgrade to the existing signal system that will improve safety, traffic management, service, and operating efficiencies. Enhancements include signal system upgrades and new signal houses, as well as wiring, power, and track components. ATC installation on the Needham Line is on schedule to be completed in November; the Franklin Line in January.

BUS Bus lanes expanded.

In partnership with cities and towns, we wrapped up bus lane projects in Somerville and Arlington to provide a faster and more reliable experience for riders of routes

77, 79, 89, 101, and 350. We also began painting a new bus lane on Brighton Avenue in Boston.

GREEN LINE Track and signal improvements, intersection upgrades, flood protection, station upgrades.

This October, crews replaced 2,000 feet of track on the B and C Branches and installed over 10 miles of signal cable on the D Branch. We reconstructed four intersections. The 30 intersection upgrades are five months ahead of schedule, with the remaining seven to be completed next month. Also, we laid the structural foundation for flood-preventing doors at the Fenway Portal and installed over 9,300 feet of fiber-optic cable in the area. We updated lighting and painted Park Street Station.
