The Mad Engineer

The Haunted Train (also referred to as Old Engine 25) is a phantom 4-8-2 Mountain type steam locomotive that appears once a year at an abandoned train staton in Hillwood, driven by the ghost of its mad engineer. Arnold, Gerald, and Helga decided to check the legend about him, but discovered that it was nothing more than one of Grandpa's tall tales. Or was it?


In 1956, Old Engine 25 was a 4-8-2 Mountain-type steam locomotive of the Great Northern Railroad. However, one night, during a coach-stock movement from a rail yard to Hillwood's old Union Station, the engine was allegedly derailed by its engineer who, for reasons unknown, suddenly went insane. No wreckage was ever found, except for part of the locomotive's throttle, which was still being clutched by one of the engineer's gloves. (Apparently, it was also the only piece of the engineer that was ever found.)


There are a few theories as to why the engineer suddenly went mad that night. 

  • It could be that the engineer had some kind of mental problem (possibly schizophrenia or antisocial personality disorder) that required him to take special medication in order to function properly. If this is the case, then the engineer may have forgotten to take his medicine before going to work, or ran out of medication and was unable to get more, resulting in him losing control and going mad.
  • It could also be that the engineer was experiencing marital or financial troubles at the time, and the stress caused him to be driven over the edge.
  • It is also possible that the Great Northern Railroad had layid off several employees due to low revenues, and the engineer was one of the employees that was fired. As a result, the engineer decided to get even with the company by derailing the train, which would cost the Great Northern Railroad more money, and tarnish the company's public image.
  • Another possible theory is that the locomotive was not an original Great Northern locomotive, but was instead purchased from another railroad. Perhaps the engineer (or other engine crewmembers) disliked it because it was not an original Great Northern design, so the 'mad' engineer intentionally crashed her in an attempt to wreck it beyond repair, leaving it to be sold for scrap.
    • This theory may have some merit (at least in part), as Engine 25 does not look anything like a real-life Great Northern locomotive, but closely resembles a Norfolk & Western K-1 class 4-8-2, which is a steam engine from the eastern United States.

Urban legend

Engine 25 and its mad engineer, under the name of "The Haunted Train," are the subjects of an urban legend told by Grandpa, asserting that the engineer drove the train straight to the fiery underworld, and that on the anniversary of the train's wreck, it would return to collect fresh passengers to bring to the underworld (which was refereed to as "the Zone of Darkness"). (For further details, see the Legend of the Haunted Train.)

The Truth?

Evidently, after the wreck of Engine 25 and its train, the Great Northern Railroad salvaged and restored the locomotive and built or allocated a new consist of coaches for it. The engine avoided the scrappers torch and survived to the present day, perhaps through a preservation movement when the Great Northern replaced all of their steam locomotives with diesel power in 1950s. No doubt being a steam engine, it went through a period of abandonment and neglect before being reinstated to service. Engine 25 is shown to be still operating at a nightly workers train run by the current railroad company (presumably from a newer station in another part of town, as the station in the episode is abandoned and the train only stops there to take on water from the water tower) to Hillwood's steel-mill. Arnold takes this as evidence that Grandpa made up the legend, but Grandpa himself remains ambiguous on the subject, after which Brainy and the viewer are treated to a vision of Engine 25 passing through the countryside en route from the steel mill, with the phantom of the engineer telling his tale in a song. Although never stated it is possible that Grandpa was Engine 25's fireman at the time  and knew the engineer personaly ( As he mentioned that he worked for the railroad earlier). Since the mad engineer's ghost is the only one in the cab, It could be that Grandpa was with engineer on that fateful night, shoveling coal. When he relised that his coworker was insane, he jumped in panic, thus saving himself and witnesing the crash. If this is the case, He may have heard about aleged sightings of the ghost train and it's mission, but never belived it, which is why he willing let Arnold and his friends go to the old station.

  • In the field of paranormal investigation, the Haunted Train would be classified as a Residual Haunting, because it visits only on the same day at the same time every year, and follows the same pattern. However, this only holds true for the train itself, as the ghost of the engineer is observed singing on the locomotive's pilot beam instead of behind its controls. As a result, the Haunted Train's engineer would be considered an Intelligent Haunting.
  • The engine itself strongly resembles a Norfolk & Western K-1 class 4-8-2 Mountain type steam locomotive, with the front pilot of a N&W streamlined J class 4-8-4.
  • Grandpa says the accident happened 40 years ago. Since the episode aired in 1996, this means Engine 25 crashed in 1956.
