In 1964, the outer loop track was removed. Instead, a new crossover switch was installed to allow southbound streetcars from the through track to reach either side of the southbound platform. There have been proposals to reconnect the outer loop, to allow trains on the outer inbound track to be turned around at Park Street, but this has not been done because of the cost of structural reinforcements that would now be required. A short stub "pit" track for emergency service remains within the inner loop. In 1966, the south headhouse on the southbound platform was converted to an information booth for the new Freedom Trail.
