Editing The Sacred Engine (section)

== Trivia ==

* Mr. Wilford built the engine when he realized CW-7 would freeze the world.
* Despite Curtis shoving his arm into the machinery and causing a critical engine shutdown, the locomotive didn't stop or slow down. We can assume it continued running by momentum and left-over energy, however it is unconfirmed.
* Some users speculate there are "turbines" in the "wings" that stick out of the top, however this is unknown.
* It could be theorized that the main headlight at the front is the only window that can be looked out through in the manual input cockpit, however this is unlikely.
* The exterior seems to be inspired by 1930s art deco streamlined locomotives, specifically a stream-lined New York Central Hudson.
* The locomotive has a 0-4-4-0 wheel arrangement. 
* In some concept art, the locomotive was supposed to have a deployable plow at the front, which would deploy when the train needed to break through ice.
* When Claude shoots up towards the ceiling, Mr. Wilford gets worried and tells her to mind the engine. Because of this, we can speculate that after 18 years the engine has began suffering mechanical issues besides parts going extinct, and that Wilford is referring to the engine instead of Claude when he says that she is getting sensitive. 
* It is implied the "core" of the perpetual motion engine doesn't need to be running at all times to keep the locomotive going. We only see it active when Wilford walks Curtis up to it.
* It's implied Mr. Wilford never leaves the engine, which means he would have to sleep in it. However, there are no beds present in the interior. It could be that one of the wooden cabinets open up to a bed, however that would require more external space.
