A 2004 study stated that since tracks to Arborway would be street-running along South and Centre streets, trolley traffic would increase local congestion and could potentially block emergency vehicles. Councilor John Tobin asked the MBTA to remove the tracks in March 2005, which by then had (along with the overhead poles) deteriorated to the point where they were not usable. The Arborway Committee filed suit in 2007, but an appeals court ruled in January 2011 that the lawsuit was a decade too late to be considered – effectively ending any attempt for the restoration of streetcar service for the foreseeable future. The City of Boston has proposed extending the E branch southward to Hyde Square in Jamaica Plain.
