Sodor and Mainland Railway Numbers 1 and 3

According to "The Island of Sodor: Its People, History and Railways", there were four 0-4-0T engines with open cabs and square tanks that operated on the Sodor and Mainland Railway from 1883 until the line went bankrupt. Little is known of the line's #1, #3 and #4, except they were named Shaun, Jacob and Harry respectively. It is not certain if they had cameos in "Very Old Engines" or not, as the four engines are all of the same design, a Neilson 0-4-0 box tank.
