A man who caught on fire while riding atop a Metro-North Railroad train Friday night is still recovering at a hospital, officials said.

Ricardo Chavez, 36, was taken to Jacobi Medical Center in the Bronx after riding on a New Haven Line train from Grand Central Terminal headed to Stamford, Conn.

"He is in fair condition," hospital spokesman Mike Heller said yesterday. Heller could not give any additional information about the patient.
