Stafford is a battery-electric shunting engine.
When Stafford first arrived on the Island, Thomas was given the job of show him around but Spencer the snooty engine warned Stafford that Thomas might run out of coal but Stafford ignored Spencer's warning and raced away after Thomas to begin the tour but Stafford's battery ran out and Thomas had to shunt the new engine to the Steamworks to recharge his battery when Stafford was recharged the tour went on but Thomas began to slow down and Stafford got in front Thomas knew that he was running out of coal right away but then he stopped Thomas had completely ran out of coal and Stafford went on without him Thomas tried calling to Stafford but Stafford couldn't hear him Thomas was stuck there for ages and ages until Stafford arrived with James, Edward and Toby. Stafford is now a Really Useful engine.
Stafford is based on the North Staffordshire Railway's battery-electric No. 1.
