Great Adventure’s El Toro roller coaster is undergoing re-tracking after the ride malfunctioned this summer.

A video posted on the YouTube channel Coliwood Studios shows some of the repair efforts.

El Toro malfunctioned during a ride in August. Fourteen people were injured.

The state determined that parts of the track’s support columns were structurally compromised.

The park previously reported that it is working to have the ride reopened by next year.
