Car Accelerates On Its Own Problems of Toyota Scion Xa

During a routine drive home, I drove over rail road tracks and the car began to accelerate without my foot on the gas pedal. The car continued to accelerate with both feet on the break. I verified that the floor mat was not stuck on the pedal. I placed the car in neutral and the engine was still pegging. I also tried to depress and release the gas pedal several times and that did not stop the acceleration. In order to keep from crashing, I had to keep my feet firmly on the break. This unintended acceleration was occurring for about a quarter mile. I attempted one final cycle of the gas pedal (depress and release) and that finally stopped the acceleration.

Sudden acceleration incident. First time it happened. 2006 Scion Xa. Driving back from n. M. On I-25. Going approx. 65 mph. Was passing car on right when came to a hill. Had to accelerate. Suddenly car engine revved up, made a loud noise and rapidly accelerated. I couldn't slow it down because the brakes wouldn't work. I managed to get around the car and tried to slow down the car so that I could get off on the right shoulder and stop the car. Somehow managed to slow the car enough (I'm not sure how because the brakes wouldn't work) to get off on the right shoulder. Pulled the emergency brake to stop the car and turned it off. Tried to start it again, and it was doing the same thing. Turned it off and waited for awhile. Finally turned the car back on, and it was operating normally. Managed to get to my destination safely. Haven't taken it to Toyota. Not sure they would do anything.
