Churchville's population boom and growth as a commuter haven took place in the mid-1980s, just after the town lost its commuter railway line. Trains served the town until January 14, 1983 via SEPTA's Fox Chase-Newtown Rapid Transit Line. The station, and all of those north of Fox Chase, were closed due to failing diesel train equipment that the then-cash-strapped SEPTA could not afford to rehabilitate. As a result, ridership was low and the service cancelled on a "temporary" basis. As such, Churchville Station still appears in SEPTA's publicly posted tariffs.

Although rail service was initially replaced with a Fox Chase-Newtown shuttle bus, patronage remained light. The traveling public never saw a bus service as a suitable replacement for a rail service, and the Fox Chase-Newtown shuttle bus service ended in 1999.

The Churchville Historic District was added to the National Register of Historic Places in 1995.

In the ensuing years since 1983, there has been heavy interest by both residents and politicians in resuming passenger service to Churchville.

In September 2009, the Southampton-based Pennsylvania Transit Expansion Coalition (PA-TEC) began discussions with township officials along the railway, as well as SEPTA officials, about the realistic possibility of resuming even minimal passenger service to relieve traffic congestion in the region. Plans call for completing the electrification to Newtown, as originally planned in the late 1970s.

PA-TEC's efforts have received overwhelming bipartisan support by both Bucks and Montgomery County officials, as well as at the state level, despite SEPTA's overall reservations. However, SEPTA has also confirmed they are willing to reestablish regular commuter service if strong political support exists in both counties.

The Churchville Nature Center, operated by the facility of the Bucks County Department of Parks and Recreation, protects 65 acres of wildlife preserve. The center features a visitor center with exhibits, a reptile room, a recreated 1500s Lenape village, a seasonal native butterfly house, gardens and 2 miles of trails.
