B Branch Track Upgrades (2023)

In 2023, we accelerated trackwork on the Green Line. In July, we fully replaced over 2,800 feet of track between Griggs Street and Packard’s Corner, and near Blandford Street Station on the B Branch.

Replacing this track helped address speed restrictions in the area and improve the overall safety and reliability of service.

Rider Benefits

  • Safety: New rails, ties, and ballast reduces the risk of unplanned service disruptions
  • Reliability: Increase speed for a more consistent schedule
