A Tri-Rail commuter train struck and killed a pedestrian early Monday in Pembroke Park, an accident that disrupted the launch of the railroad’s new express service to downtown Miami, a company spokesman confirmed.

The train was headed northbound when the incident occurred along a section of track between Hallandale Beach Boulevard and Hollywood Boulevard within the town of Pembroke Park, shortly before 5:30 a.m. The victim was not immediately identified.

The accident effectively halted the southbound inaugural run of an express train that originated in West Palm Beach and was headed for the MiamiCentral station.

Spokesman Victor Garcia said the company summoned buses to transfer southbound express passengers whose train ride ended at a scheduled stop at the Fort Lauderdale-Hollywood International Airport station at Griffin Road. They were given bus rides to the MetroRail transfer station in Hialeah, where they took other Tri-Rail trains or MetroRail to their final destinations.

Passengers on later trains were taken by bus from Hollywood to the Golden Glades station, where they boarded Tri-Rail trains to complete their journeys to other stations in Miami-Dade.

Garcia said the northbound train involved in the accident originated at Miami International Airport. It then stopped at the Hollywood station and offloaded the passengers who were transferred to another train so they could continue their trips north.

The tracks at the accident site were cleared and trains resumed uninterrupted service through the area at 9 a.m., Garcia said. The day’s inaugural northbound express was expected to depart from MiamiCentral for West Palm Beach at 5:35 p.m. as scheduled.

In late May, Tri-Rail announced its “one-seat” ride from West Palm Beach to downtown Miami, with a start date of Monday. One southbound train leaves at 6:05 a.m. and arrives at 8:05 a.m. The return northbound train leaves Miami at 5:35 p.m. and arrives in West Palm Beach at 7:05 p.m.

The express trains, which travel along the state-owned rail corridor that runs mainly to the west of I-95, stop at Boca Raton, a Griffin Road station near Fort Lauderdale-Hollywood International Airport and a MetroRail transfer station before hooking eastward to the MiamiCentral station. Tri-Rail operates 19 stations in Palm Beach, Broward and Miami-Dade counties with its most southern terminus at Miami International Airport.
