Line Trolley Museum which is run almost entirely by volunteers. Antique equipment is repaired and restored at the museum. The collection also includes a small number of "trackless trolleys" (trolley buses) and motor buses (diesel- or gasoline-powered buses). In fall 2008, construction was started on a short trolley bus line, to allow the museum's trolley buses to operate. The planned line is a loop about long, with a branch into the maintenance and storage building. The first section was tested under power in April 2009 by 1947-built ACF-Brill trolley bus 205, which the museum acquired from the Philadelphia trolley bus system when it was retired from service by SEPTA in 1981. Construction of the line was about half completed as of September 2010 and due to continue in 2011. Regular operation – proposed to take place about once a month – is not expected to begin before 2012. The Shore Line Museum also owns two other trolley buses, ex-Philadelphia 210, identical to No. 205 (and acquired at the same time) and being used only as a source of parts, and ex-Massachusetts Bay Transportation Authority (Boston-area) 4037, a 1976 Flyer E800 which the museum acquired in 2009 and which is also able to operate on the line.
