Splatter and Dodge (collectively referred to by Diesel 10 as "Splodge", a portmanteau of their names) are two diesel shunters, who were Diesel 10's bumbling minions.
Splatter and Dodge are two diesel shunters who, at one point, worked alongside Diesel 10. Diesel 10 referred to the two as "Splodge", claiming he did not have time to say both names. They did not take a liking to their boss when he collectively refers to them as "Splodge" and grew impatient with them when they asked him questions about his scheme.
Diesel 10 wanted to rid the railway of steam engines, and they were complacent with his plans, regularly keeping a lookout for their boss and being present when he was scheming. As time went on Splatter and Dodge spent their time mocking their boss and pointing out the flaws in Diesel 10's scheme causing Diesel 10 to lose his temper and cause trouble during his temper problems.
What happened to them after that is unknown, although it can be assumed they returned to the Mainland.
Both engines are simple-minded, awkward, cowardly and tend to banter. Splatter is the more talkative of the two, while Dodge is more intelligent. Although Percy fears them, they do not have the intelligence or villainy to match Diesel 10's. They enjoy watching Diesel 10's plans backfire, but are also prone to making a mess of things. Despite initially siding with Diesel 10, they seem reluctant to destroy a fellow engine, even a steam engine, and eventually abandon Diesel 10 in the end.
Splatter and Dodge are based on BR Class 08 diesel-electric shunters. Over seventy members of this class survive today in preservation, while around 100 remain in service on the national rail network. They were in fact the most successful shunting engines in the world, with 996 of them built. Diesel, Rose, Paxton, Sidney, Ulli, the Mainland Diesels, 'Arry and Bert are also members of this class.
However, unlike the other BR Class 08s, Splatter and Dodge have been modified without ladders going up each side of their fronts.
Splatter is painted purple and grey while Dodge is painted olive and grey. Both are heavily weathered, and both have their names painted on their sides in white.
