Trinity Mills station is a train station in Carrollton, Texas. It serves DART Light Rail's Green Line^[3] and DCTA's A-train hybrid rail line. It is the southern terminus of the latter. On A-train maps, the station is represented by a yellow circle containing the DART logo.^[4]

The station is located at the intersection of Interstate 35E and the President George Bush Turnpike (PGBT). It is named for Trinity Mills Road, a frontage road for PGBT, which in turn is named after a mid-19th century settlement that was later annexed by Carrollton.

History

North Carrollton Transit Center

North Carrollton Transit Center, located about 0.5 miles (0.80 km) east of the current station, opened on October 31, 1988.^[5] It was one of the first DART stations with an indoor waiting facility, along with South Irving Transit Center.^[6]

The facility was serviced by several bus routes, most notably an express route between it and Downtown Dallas. When Trinity Mills opened, the express route was discontinued in favor of the Green Line, and all other routes were moved to Trinity Mills.^[7] The facility has since been demolished.

Trinity Mills

In 2000, DART released an investment study on the "Northwest Corridor", which includes the present-day northern segments of the Green Line and Orange Line. The proposal included three stations in Carrolton, including one at North Carrollton Transit Center.^[8]

In 2002, the City of Carrollton proposed names for the three Carrollton stations on the corridor. The proposal named the station adjacent to North Carrollton Transit Center "Trinity Mills", moving the "North Carrollton" name to the terminus. This was done to ensure that "Carrollton" would appear on the train's destination signs.^[9]

In 2007, DART officials broke ground on the Green Line in Carrollton.^[7]

In late October 2010, DART offered a preview run of the Green Line, which ran between Downtown Carrollton and Trinity Mills, during the first annual Festival at the Switchyard.^[10] A month and a half later, on December 6, 2010, the Green Line's second expansion, including Trinity Mills, opened.^[2]

A-Train service began June 20, 2011 with a ceremonial ride from Downtown Denton Transit Center to Trinity Mills.^[11]

Development

In 2003, Carrollton purchased a 12.5 acre site adjacent to Trinity Mills for the purposes of future development.^[12]

In 2020, Carrollton announced the creation of Trinity Mills Station, a transit-oriented development zone in a 25-acre site adjacent to the DART station.^[13]
