Former Beatle Ringo Starr trades his yellow submarine for a blue train conductor's hat in a new children's television program.

"Shining Time Station" makes its debut on PBS later this month. To promote the program, Starr arrived in New York Tuesday on a train from Chicago with his wife, Barbara Bach, and his co-stars Brian O'Connor and Nicole Leach."Shining Time Station" is an outgrowth of a British show that Starr narrated off-camera and he likes his on-camera role in the new show. "It's fabulous being 18 inches tall again," he said. "I had a lot fun making `Shining Time Station.' "
