Tankers

There are other wagons which resemble the two main wagons, Tar Wagons and Milk Wagons.

Sodor fuel
The sodor fuel wagons are bright yellow. They are a common sight but they are not significant to any plots.

Blank wagons
Wagons without any livery. It is unkown what purpose they have. Some have "truck" faces on them. They typically come in black and white.

Jam wagons
Similar to tar wagons, Gordon had an accident with them
