SALT LAKE CITY -- TRAX service is delayed on all three lines in Salt Lake City Wednesday after a train caught on fire late Tuesday night.

There were about 30 people on board the when the wire that powers the TRAX train malfunctioned near Main Street and 350 South around 10 p.m. Tuesday.

Video captured by passengers and bystanders show the fire from inside and outside the train.

All passengers made it safely off the train and UTA says one man was taken to a hospital to be treated for a minor wrist injury.

Carl Arky, a UTA Spokesman, said riders should expect additional delays Wednesday and monitor the agency's Twitter feed for updates on service delays. He said riders should consider alternative transportation if possible.

"We really do stress that people check our Twitter feed in the morning and maybe think about an alternative way of getting downtown," Arky said.

Arky said all three TRAX lines (red, blue and green) will be affected Wednesday and authorities said repairs will likely continue throughout Thursday's regular service hours. UTA said in a press release regular service may be restored by Friday morning, but until then, a bus bridge will remain in effect.

Authorities still are unsure what caused the malfunction that sparked the fire. Fox 13 News will update this story as more details emerge.
