Diesel is a devious Diesel shunter. He often boasts that diesel engines are revolutionary and steam engines are no match for them, when in reality, Diesel is usually the cause for confusion and delay due to his oily and schemey tricks, hence the nickname 'Devious Diesel'. But given a chance, Diesel wants to be Really Useful.



  • Diesel is the first HO Scale engine to have a CGI series-style face.
  • Diesel's Bachmann model has silver siderods, similar to his model as seen in seasons 2-6 of the television series.
  • Recent releases of Diesel mistakenly have him with red buffers and black buffer housings.
