- Kenji is the second Japanese engine introduced in the show, the first being Hiro.
- Kenji is the third catenary powered engine introduced in the show, the first being Etienne and the second being Gustavo. He is also the only catenary powered engine to travel to Sodor.
- Despite this, he has only been seen using his catenary at Ulfstead Castle.
Someone should also add that, as of Kenji on the Rails Again, he is to date the only engine to have been converted to run on an alternative source of power, as a nod to engines being converted from coal or diesel for example, to oil, electricity, battery power, etc...
