Ten is a South African Class 26 4-8-4 built in 1953 for Transnet Freight Rail (when it was known as South African Railways). He derailed a lot, and was bought for 2 bucks and half a melted ice cream cone by Casey Jones. He was repainted into their Maersk Sealand exclusive scheme, and works all day with Carl on their rails. When he discovered a old part of the line, he and Carl helped restore it with the Dock railway locomotives.
Ten can be busy hauling Maersk Sealand trains at speeds of up to 51 miles per hour (82 km/h), but he can be normal at some times.
Ten is based on a South African Class 26 4-8-4.
