Isobella

Isobella is a yellow steam lorry who works for the Sodor Construction Company.

Thomas & Friends
Isobella once had to deliver a piano, but she lost control and ended up dangling over of the side of a retaining wall next to the railway line. Kelly had to rescue her.

While working on the foundations for a dairy barn, all the diesel-powered machines ran out of diesel fuel. As she was the only machine still in working order, Isobella had to collect some barrels of diesel fuel for the machines.

Personality
Isobella is as sweet and kind as she is a hard worker, but not when she gets dirty, which is why she tells others to "mind her paint". She can also be rather cheeky and temperamental.

Basis
Isobella is based on a Sentinel DG4 steam lorry with a flatbed. Elizabeth shares the same basis.

Livery
Isobella is painted yellow with red and black lining. Her number 22 is painted on the sides of her cab in black.
