The Railway Series
Wilfred was built at the Swiss Locomotive and Machine Works in Winterthur, Switzerland, in 1900. Soon afterwards, he arrived on Sodor during the opening of the Culdee Fell Railway.
When Culdee returned from an overhaul, Wilfred and Ernest informed him about changes that happened to the railway. Later, Wilfred and his coach were later delayed at the Summit after Lord Harry derailed at the points. Culdee and Wilfred teased him for being a "wreck".
According to Sodor: Reading Between the Lines, he and Ernest were superseded by the more modern Nos. 6-8 in 1964.
Wilfred is a kind old mountain engine. A hard worker, he is very cautious and gets upset at the carelessness of the other engines. He is known as the musical engine by the other mountain engines because he loves to whistle as he ascends and descends the steep hills.
Wilfred is painted purple with orange lining. The number "3" is painted on the sides and back of his cab in yellow and he has red nameplates, with his name in gold, on the sides of his tanks.

- Like the other mountain engines, Wilfred is equipped with a face at each end.
- “Wilfred," Culdee called. "Who is this wreck?!"
"It's Lord Harry, didn't you know?"
"It looks like Old Harry, its fat as Old Harry. But of course, it can't be Old Harry."
"Why ever not?"
"You see Old Harry's an up-to date engine. He can go twice our speed in perfect safety!”

- “It's important work!" protested Wilfred, "and tough too!"
"Tough? That little lot?!"
"Yes, tough!" said Culdee. "Have you ever been across Devil's Back, in a gale?!"
"No," said No. 6 thoughtfully. "But I see what you mean.”
