History
The 52 Allentown route was created in 1984 by renaming what was then the ''49 Arlington–Warrington'', itself created in 1971 by combining portions of the ''48 Arlington'' and ''49 Beltzhoover'' lines. In April 2010 the 52 Allentown was rebranded the "Brown Line" by the Port Authority.
Prior to being discontinued, Brown Line service was severely reduced, operating only during Monday to Friday rush hours, with bus route 44 substitute providing service at other times. The

considered ending all Brown Line service, but this would have provided only limited savings unless the tracks and overhead wires were also decommissioned. More importantly, however, the Brown Line's tracks provide an alternate route when the
Mt. Washington Transit Tunnel is closed (either due to planned maintenance or a stalled vehicle), allowing
Red Line or
Blue Line services to continue operating, albeit behind schedule since the Allentown routing takes five to eight minutes longer than via the tunnel, and at reduced frequency due to a short single-track section.
On March 27, 2011, the Brown Line service was withdrawn due to a system-wide 15% service cut.

As of February 2021, The Port Authority's newly released 25-year plan includes the possibility of reviving service on the Allentown line due to continuing growth of the neighborhood.
In February 2025, the tracks temporarily reopened for Red and Blue line trains at all times and the Silver line on weekends due to the Mount Washington tunnel closure, with one temporary intermediate stop at Warrington + Allen.
