Wade said it's the first time in his 19 years on the job that he's seen a train accident with such a high number of injuries. None of the injuries was life-threatening.
A spokesperson for Sacramento Regional Transit later described the incident as a collision between a passenger and maintenance train, but officials are still investigating the cause.
The train appears to be upright and on the track, Wade said.
Sacramento fire officials said 15 ambulances and 40 firefighters were on the scene, KCRA reported.
