An unidentified 28-year-old male cyclist died Tuesday morning after he was struck by a commuter train in southeastern Denton.
Local police and firefighters were called to the scene near Lakeview Boulevard and West Shady Shores Road about 11:45 a.m.
The victim, who authorities identified as a registered nurse at Medical City Denton, was riding his bicycle with a friend on the Denton Katy Trail when a southbound Denton County Transportation Authority A-train hit him, according to police. Department spokesman Shane Kizer said police are investigating the circumstances surrounding the incident. He said the crossing arms and warning lights were working at the time.
DCTA President Jim Cline said the train was traveling about 45 mph at the time of the collision. It stopped about 80 yards away from the impact.
All 11 passengers on board were not injured and eventually were taken from the scene, the agency said in a press release.
"Our sincere condolences are with the individual's family and friends who are mourning their loss," Cline said in a press release issued by DCTA earlier in the day. "The safety of our passengers and our community is of utmost priority to DCTA."
The crash occurred roughly 2 miles south of MedPark Station, which is in the 3200 block of Medpark Drive. According to the release, the agency implemented a temporary bus service between the MedPark and Highland Village/Lewisville Lake stations to keep services moving.
The A-train has struck five pedestrians or cyclists since DCTA launched its commuter rail service in 2011, Cline said. He said three of those collisions resulted from people trespassing on DCTA property.
The portion of the Denton Katy Trail where the victim was traveling runs outside of the crossing arms on Lakeview Boulevard. Although police said the arms were down and the signal lights were operational, people walking or biking on the trail are able to cross the tracks at any time.
DCTA built the trail, which runs parallel to the tracks from downtown Denton through Corinth, in 2011.
"[The trail] was consistent with current design practices," Cline said.
