The couple drove off Mykawa near Griggs in southeast Houston and 911 operators had to use the signal from their cell phone to help find them.
Firefighters started searching the area and used flashing lights and air horns to let the couple know they were nearby. They found the couple about 20 minutes after receiving the 911 call. They used a basket to get the couple out of the culvert.
"It looks like they're going to be OK. Great job by OEC, dispatch, and the call takers to get us to the right place to go," said Senior Captain Edward Havlice with the Houston Fire Department.
The victims were both taken to the hospital and are listed as stable. It is not clear why they kept driving after going off the road and going over railroad tracks.
