The toddler was taken to Children’s Hospital of Pittsburgh and on Friday, he remained in critical condition, KDKA reported.
Park spokesman Jeff Croushore told InsideEdition.com that the boy was conscious and talking after he fell from “the middle part” of the wooden track.
"Our thoughts and prayers are with the boy and his family," he said. "A full investigation has begun to determine the cause of the incident." Because the review is ongoing, "I can't comment too much further than our statement," he said.
The ride opened in 1938 and is an older-style attraction made of wood that carries “riders up and down along a wooded hillside,” then makes a swooping curve before returning to the station, according to the park’s website.
No information was released about the child or his injuries. Riders on the Rollo Coaster must be at least 36 inches tall. Children under 48 inches tall must be accompanied by an adult, according to park rules.
Sources said the boy suffered head and chest wounds, the station reported.
The roller coaster has been closed pending an inspection and investigation by the Pennsylvania Department of Agriculture, along with local agencies.
