Logan is a steam shunter who looks like a diesel, and works at the Crosby Coal Company.
Logan the Sentinel Shunting Engine was built in 1929 at Sentinel Waggon Works. He was numbered 7190 and retired in 1959, the year he was bought by the Crosby Coal Co. & Mines. The company saved him from scrap and modified him to resemble his twin Joyce 7109. He was renumbered to match his twin.
Logan is a rough and tumble, strong little shunter. He is very friendly and hardworking. He knows the value of patience and how it is possible to correct a mistake.
