With repairs to the destroyed JFK/UMass signal bungalows continuing apace, the MBTA announced today it hopes to restore fully automated signaling between JFK/UMass and Broadway by Aug. 15, which should cut five minutes off the longer Red Line commutes.
The T says that means it should take 35 minutes to get from Braintree to South Station, down from a peak of 55 minutes right after the
still unexplained June 11 derailment. Before the derailment, the trip normally took 30 minutes.
The T says its repaired the three destroyed bungalows, which contain miles of wiring and signaling equipment that control 29 signals and 11 switches along the Red Line, and added a fourth new one.
Since the derailment, crews have been working to salvage, test, and assess the repair needs of over a thousand damaged electronic components and pieces of equipment in the bungalows. In addition, nearly 20 miles of signal cable were tested for connectivity and repaired as well as over 800 signal control relays, 35 track circuits, and numerous other pieces of related equipment.
