Farmer McColl is a farmer who owns a farm on the western side of Sodor.
Farmer McColl is the owner of McColl Farm, an agricultural operation which dominates the farming industry on Sodor in joint with Charles Laxey. He traded exclusively with Mr. Percival prior to the summer of 1945. Following Sir Topham Hatt's closure of trade between his railway and the Skarloey Railway, McColl was very unhappy with the arrangement. As such, he attempts to send a tractor with grain to Mr. Percival, only to watch it go up in flames, most likely retaliation for breaking Hatt's trade embargo.
