Communications work by T will disrupt some bus service

By Noah Bierman, Globe Staff

Bus riders may notice added disruptions to their service over the next month as the MBTA moves to a new radio frequency for its communications system, as required by the Federal Communications Commission.

The T will begin work on the project Tuesday, and communications workers are trying to beat a one-month deadline set by the transit agency, according to an MBTA press release. While the T reconfigures its communications system, GPS units on buses will be down, meaning dispatchers will not have the ability to see where buses are on the grid to make real-time schedule adjustments.

In addition, the count-down signs on the Silver Line bus shelters on Washington Street that tell passengers when the next bus is arriving will be unavailable during the project.
