The emergency shutdown he had performed to prevent a pressure explosion tearing through the ship or blowing the entire engine out its backside had caused a certain degree of damage to the engine and a major loss of efficiency in heat regulation. That meant they now had to burn more coal to get less steam pressure, wasting more water through innumerable leaks and patched pipes. The ship now had a constant damp atmosphere that Handy did not care for. So now they had to watch their water supplies more closely and he had to seriously consider making a pit stop at any potential Equestrian town that might have a train or relay station they could buy some coal from.
