The MBTA, which just announced completion of some serious track improvements along the B Line, is now telling riders to brace for trolley-to-trolley transfers and delays because of a broken rail at a switch at Kenmore station.
Seems a rail broke at Switch 61 at Kenmore. Workers were able to clamp it into position to at least allow through B Line service, but that, of course, doesn't help people on the C or D lines. Or as the T puts it:
C and D Branch eastbound service is continuing to terminate at Kenmore. Riders can transfer there to a B Branch train for further eastbound service. Passengers looking for westbound service can take a B train to Kenmore to transfer to a C or D train.
