When Salty was experiencing engine trouble, Sir Topham Hatt brought Porter to Sodor to work at Brendam Docks while he arranged for Salty to be mended at the Sodor Dieselworks. When Porter arrived to help out, Salty was convinced that Porter had been sent to replace him. After some mishaps, Porter managed to stop Salty from having an accident, then using his sandboxes to sand the rails after Salty accidentally spilt oil on them. Later, the Fat Controller told Salty that he was to work with Porter and that he was not going to be replaced.
Later, Porter helped arranged "The Flying Kipper" for James after he made Henry late the previous night. When Bill and Ben teased Harvey about "going fishing" and made fun of Porter's three domes, Porter helped Harvey see the positive side of being both a crane and an engine.
