BoCo

**BoCo** is a green mixed traffic diesel engine, who primarily works on Edward's Branch Line and occasionally on the Main Line.

## Appearance

BoCo is a diesel engine who's painted in the BR Brunswick green livery. He has yellow warning panels on his front and back end. In the television series, BoCo is painted in a more vibrant shade of green without yellow warning panels on his front and back end. He has ten wheels and oval-shaped buffers. And his number "**D5702**" is painted on the sides of his cab in white.

## Personality

BoCo is a tame diesel engine, who is sensible, kind, and has a decent sense of humour. He is also very disciplined, as seen as he stops Bill and Ben from their pranks. Upon his arrival, he was unfortunate enough to be set upon by the mischievous Bill and Ben, when, thinking he had intentionally stolen their trucks, they pretended to be one engine and nearly made his eyes pop out. BoCo is now wise to the tank engine twins' pranks though he still somewhat humours them to a point. He is also good friends with Bill, Ben, Edward, and Duck. He is a true friend and is often willing to stick up for the underdog. BoCo is firm, but fair and friendly in his nature, not being afraid to speak his mind. Even Gordon soon thought of him in high regard when he "saved" him from Bill and Ben's antics. BoCo upholds a more praiseworthy and respectable, likeable image for diesel engines everywhere, being happy to show the more pompous steam engines that diesels have their uses. BoCo helps bring good order across Edward's Branch Line, even occasionally pulling Main Line trains, as the Fat Controller recognises how versatile he is.

## Trivia

* BoCo's name is often mis-capitalised as "Boco". One example of this is on his nameboard.
* On the cover of the My Thomas Story Library, BoCo's wheel arrangement shows a Co-Co. This was fixed in the 2011 re-release.
* In the television series, BoCo and Daisy shared some of the same face masks, with Daisy's face having added make-up. They also share the same chassis and powered "Bo" bogie.
* BoCo is the first of two characters to mention their own real-life basis in the television series, the other being Merlin. In this case, Edward stated that BoCo was a *Metropolitan-Vickers, diesel-electric, Type 2,* in The Diseasel.
* BoCo is the only engine introduced in between the first and third series not to return in CGI.
* BoCo had a total of seven facial expressions, two of which (sleeping and laughing) were never shown on-screen. However, his sleeping face appeared in a promotional picture of the third series episode, One Good Turn, and his laughing face only appeared in a promotional image from the eighth series.
* Four of BoCo's face masks are now owned by Twitter user TomsProps.
* BoCo has had two different horn sounds over the years:
	+ In the second series, he shared the same sound as Diesel's, but in a lower pitch.
	+ In the third series, he received a two-toned horn, similar to Mavis', but some steps lower-pitched.
	+ In the fourth series, he regained his original horn sound after it was reused for Daisy in Series 4.
* In a 2015 interview with Sodor Island Fansite (SiF), railway consultant Sam Wilkinson expressed interest in reintroducing BoCo into the CGI Series, if this had happened, this would have become his first appearance and speaking role since the fifth series episode Double Teething Troubles.
* BoCo's name is a joke on his wheel arrangement, Co-Bo.
