D199 is an antagonistic diesel who takes an explicit dislike to steam traction.
D199 first visited the NWR in the early 1960's, along with Bear, the latter stayed while D199 was sent away for his rude behaviour and un-reliability due to his attitude. He later returned to Sodor on a passenger run to the Mainland when he met Oliver's Old Manager and conspired with him to kidnap Oliver and bring him back to the Manager's branchline. Since then, He has not been allowed to return to Sodor.
D199 is based on a BR Class 46 "Peak" 1Co-Co1.
