Sonny

Sonny was a troublesome industrial Austerity saddle tank engine who used to work at a steelworks on the Mainland

Bio
Sixteen lived at a steelworks on the Mainland, with several other engines. He spent all day shunting trucks to a place called the "tip". Engines were not allowed to travel along the track on the tip itself, as it was not firm enough to take their weight. Sixteen thought he knew better and often tried to pass the "danger" board without success.

One day, however, Sixteen took advantage of damp conditions and told the trucks to slide him past the warning notice. His fireman was told to reverse him, but before he could do so, the rails gave way and Sixteen tipped off the rails and rolled over onto the ground. He was eventually rescued but not repaired and sent to the sheds in disgrace where he remained in storage. He was eventually saved and taken to a heritage railway.

Personality
Sixteen was a naughty, careless, arrogant and awkward engine. He refused to take anyone's advice and it is also implied that he grew bored of his surroundings and was curious about the outside. After his accident, Wilbert has said that he hopes Sixteen has learned his lesson after being restored and given a fresh start in preservation.
