A small fire was reported in University City Thursday afternoon, halting train service in the area.
A battalion chief with the San Diego Fire-Rescue Department said the blaze was reported around 5:17 p.m. near the 6100 block of La Jolla Colony Drive in University City, south of the train tracks.
The fire burned approximately one quarter-acre in a canyon along the train tracks. SDFD crews were able to quickly stop it from spreading.
Officials closed the train tracks servicing North County Transit District for an hour following the fire. The closure impacted trains traveling between Sorrento Valley and Old Town San Diego.
The cause of the fire has yet to be determined.
Officials said this fire was suspicious in nature, as it sparked about a quarter-mile east of another brush fire that burned in Rose Canyon Open Space Park a few hours earlier. That fire also halted service on the NCTD train tracks.
The Metro Arson Strike Team was called to investigate the fires.
No injuries were reported.
