BoCo is a diesel who works on Edward's Branchline.


Bill and Ben were once called to the yard to help shunt trains for BoCo. The two began fighting after an incident with the turntable and soon began to give each other the silent treatment. Edward thought this attitude was counterproductive, so BoCo came up with a plan: convincing the Fat Controller to let him take a special, BoCo's own heavy goods train was left behind, with only Bill and Ben to pull - neither would be strong enough to pull the train alone, so the two had to compromise and work together to finish the job.


BoCo is a branch line diesel who works on the North Western Railway. He is very kind and wise. He often works with Bill and Ben at the quarry. He does not usually get angry, but he does sometimes get annoyed at the twins actions. He does however usually find a way to sort things out, and Edward praises him for this. He is very friendly and will always stop to help.



  • BoCo was originally intended to be a part of the Rhyndale Railway, as he can be seen in the end credits along with Derek.
