Ralph is a navy blue tender engine.
Ralph later was asked to go back to Scotland to help out around the railway. While he was there, he met Liam, who has come to the Scottish Railway after Ralph had left. The two became good friends.
Ralph is a kind engine. He does not like being called a goods engine, as he feels he is being underestimated whenever he is referred to as such. He also often tries to give the other engines advice.
Ralph is painted navy blue with light blue lining. He has his number on his tender in light blue.
