Troublesome Trucks

The Troublesome Trucks are recurring characters in the Thomas the Tank Engine franchise. They are mischeivous trucks who are known for causing engines to crash, causing destruction and derailing, damaging or destroying themselves.

In the UK, they are called the Trucks and the Troublesome Trucks, but in the US, they are called The Cars and The Foolish Freight Cars.

In Toad Stands By, it was revealed that they had a leader named S.C. Ruffey.

It is unknown what the trucks' real names are. However, there were a few trucks that have real names such as their leader, S.C. Ruffey, Fred Pelhay, Rickety and Old Bennett.

Personalities
The Troublesome Trucks, as their names describe, are naughty, mischievous and troublesome due to playing tricks on the engines and intentionally causing them to crash.

Despite causing engines or trains to crash, the trucks are frightened of some of the engines such as Donald, Douglas and Oliver because Douglas caused the Spiteful Breakvan to be smashed into pieces (even though it was an accident) and Oliver caused S.C. Ruffey, the leader of the Troublesome Trucks to come apart causing him to break into pieces.

There are also a few engines that the trucks do not play tricks on, such as Edward, Stepney, Salty, Hiro and Rebecca, as well as Toby and Mavis from fifth series onwards.

Trucks can also be considered territorial. When the trucks get used to certain engines pulling them, another engine in the yard taking them may cause the trucks to get angry and confused. For example, in an episode called Percy's Predicament, an episode of the second series, Toby and Percy switched jobs, making Toby's trucks furious and then they cause Percy to crash. In Oliver Owns Up, an episode of the third series, the trucks refused to let Oliver take them, and they demanded that Duck, Donald or Douglas took them instead.

In other countries around the world, some trucks act very differently than the ones on Sodor as some are very polite and they were even willing to help the engines instead of causing trouble.

Appearances
In season 1, the Troublesome Trucks' eyes and mouths were made of paper. However, in season 2, their faces have changed into the same type of faces that the engines have.

In some episodes, the troublesome trucks had faces that resemble a few characters' faces such as S.C. Ruffey, Toad, Bulstrode and the Spiteful Brake Van.
