Dodge and Splatter (collectively referred to as "Splodge") are Diesel 10's bumbling sidekicks.
Dodge and Splatter are two Diesel shunters who, at one point, worked alongside Diesel 10. Diesel 10 referred to the two as "Splodge," claiming he didn't have time to say both names.
Diesel 10 wanted to rid the railway of steam engines, and Dodge and Splatter were complacent with his plans, regularly keeping a lookout for their boss and being present when he was scheming.
Both engines are fairly simple-minded and tend to banter. Splatter is the more talkative of the two, while Dodge is more intelligent.
Splatter is painted purple and grey while Dodge is painted olive and grey. Both have their names painted on their sides in white, and are heavily weathered.
