Trinity Railway Express

TRE has a fleet of 11 locomotives.

• EMD F59PH IV (1994)

There are seven EMD F59PH IV locomotives that were acquired from GO Transit.  The original numbers for these were #525, #527–528 and #565–568. These were overhauled in late 2010 by the Norfolk Southern Railway and RELCO Locomotive to meet EPA standards and renumbered 120–126.[9]

• EMD F59PHI (2001)

There are two EMD F59PHI locomotives that were purchased from EMD. The numbers for these are #569 and #570.

• EMD F40PH (2022)

TRE acquired 2 F40PHs from Progress Rail in 2022. They are numbered 130 and 131.

• Bombardier Transportation and Hawker Siddeley bi-level cabs and coaches

Until 2011, the TRE fleet included diesel multiple units, in the form of 13 Budd Rail Diesel Cars (RDCs) built in the 1950s for Canadian Pacific (9), Canadian National (3) and Boston & Maine (1).[10] They were purchased used from Via Rail Canada in 1993. All were remanufactured by GEC-Alsthom in Montreal. They entered service in March and April 1997[11] – after trains leased from Amtrak and the Connecticut Department of Transportation temporarily provided initial TRE service when the RDCs were not ready in time for the inauguration of TRE service[5] in December 1996 – and thereafter provided all service for the line's first two to three years. They remained in service for about 14 years, the last cars being taken off of TRE service in March 2011.[12] In 2010–2011, 11 of the 13 cars were leased to Denton County Transportation Authority for operation on the A-train. They were returned in 2012 and placed in storage at the TRE shops in Irving, Texas. In spring 2017, 12 RDCs were sold via auction to AllEarth Rail,[12][13] a Vermont-based private company that intends to use them to operate commuter rail service connecting the Vermont cities of Montpelier and Burlington.[13] AllEarth subsequently resold two of the TRE cars to TriMet, of Portland, Oregon,[14] before they had left Texas, and those two Dallas RDCs (Nos. 2007 and 2011) were moved in August 2017 from Texas to Oregon, where TriMet planned to use them on its WES Commuter Rail service.[15] The other 10 RDCs were moved to Vermont the same month.[14]

Trinity Railway Express train with Bombardier BiLevel Coaches

Each train includes at least one locomotive unit and one bi-level cab car. Typically, one or two additional coach cars are included between the locomotive and cab car. Each cab car (and thus each train) has a restroom and passengers may move between cars during the trip. The trip from Union Station to T&P Station takes just over an hour, with scheduled trip times ranging from one hour, three minutes to one hour, eleven minutes. Track improvements are currently underway which should offer an improvement in travel times by double-tracking certain stations and sections of the route. Currently, portions of the route are single-track, requiring eastbound and westbound trains to meet only at certain points and requiring some eastbound trains to hold for 5–7 minutes to wait for a westbound train to get to the passing area.
