The train leaves the station at Mossleigh, Alberta, and by the time it comes back, the passengers have been grabbed, followed, separated from their friends, and made to crawl through the dark. This is not a haunted house you walk through and leave behind. It is a haunted house that moves, and it is billed as the only one of its kind in Canada.
The Train of Terror is the Halloween alter ego of the Aspen Crossing Railway, a heritage line that runs about 14 miles of former Canadian Pacific track through the flat farmland southeast of Calgary. For most of the year, Aspen Crossing runs gentle themed excursions along those rails: wine and cheese trains, brunch trains, a circus train, dinner theatre, and a Christmas Polar Express that ferries pyjama-clad families to the North Pole and back. October is different. October weekends and the days before Halloween are given over to the haunt, and the same coaches that carry Santa and his elves in December carry something considerably less cheerful in the fall.
The event's own organizers describe it as "Canada's only moving haunted house," and they are not shy about what that means. Guests check in at the station and then work their way through three separate haunted mazes, each with its own theme and its own cast of performers. Only after surviving those do they board the train, where the ride itself becomes the final maze, billed as the scariest of the night. The whole experience runs about two hours, including roughly ninety minutes on the rails. There are spaces to sit and visit with friends, and food and drinks for purchase, including what the railway cheerfully calls "liquid courage" before the last stretch of terror.
The disclaimer is unusually blunt for a tourist attraction. Performers are permitted to touch, grab, and follow guests, and may even take them through parts of the experience. Actors can separate guests from their group, leaving someone to face a scare alone. There are physical obstacles requiring climbing, sliding, and crawling. The event is strictly 18 and over, a rule the railway attributes to liquor licensing requirements, with everyone ID'd at the door. In its own FAQ, Aspen Crossing answers the question of what happens if the train runs late with a straight face: bad weather, extra train maintenance, zombie apocalypse, "one of the guests goes mysteriously missing." The usual stuff, of course.
What makes the Train of Terror genuinely unusual is not just the format but the ground it runs on. The line it uses was nearly erased. In 2002, the last Canadian Pacific train passed through Mossleigh, and the branch was slated for abandonment. After six years of negotiations, Jason Thornhill, the creator of Aspen Crossing, secured the rights to 14 miles of the line, and in May 2015 the Aspen Crossing Railway made its inaugural run with more than a hundred guests on board.
That purchase was the culmination of a theme Thornhill had been building for years. Aspen Crossing began as a tree farm and nursery on land that was part of the family farm, bordered by the CP tracks on one side and Highway 24 on the other. The nursery's gift shop was built to look like a typical prairie railway station. Then a chance opportunity turned the place into something stranger and better: the purchase of an 1887 rail car.
That car has a history that reads like fiction. It was built in 1887 as a business car by the Pullman Palace Car Company in Chicago, arrived in Alberta in 1913, and was rumoured to have mob ties, reportedly used for club meetings by gangsters. It found its real distinction as the rail car of Canada's 13th prime minister. Inspired by Dwight Eisenhower's whistle-stop campaigning in the United States, Diefenbaker toured the country by train and won the 1958 election by a landslide, still the largest majority in Canadian federal political history, while using the Pullman as his private quarters. It stayed in his service as a business car afterward. In 1981 it was delivered to Edmonton's Sidetrack Café, where it hosted acts including Sarah McLachlan, k.d. lang, and the Barenaked Ladies over a 26-year run. Aspen Crossing bought it in 2006, and today it serves as the Diefenbaker Dining Car, where visitors can order a Diefen-burger while sitting where a prime minister once worked to win an election.
The railway's other Halloween-adjacent claim to fame is simply that it got there first. Aspen Crossing bills the Train of Terror as the first Halloween haunt on rails in Canada, and the format has been running long enough to have its own lore and its own recurring characters. One recent season's storyline followed a Professor Grim, whose obsession with immortality leads him to hunt the scattered remains of a medieval witch, guarded at various sites to prevent their reassembly. Guests begin at Grim Manor and move through the professor's world before boarding. Earlier years ran on a zombie-infection premise, and the event has been staged at least since 2016, when tickets sold for $69.99 and trains departed in the afternoon and evening.
Mossleigh itself is the kind of place that makes the whole enterprise make sense. The village sits on what was Canadian Pacific's Lomond Subdivision, a branch line built in 1913, the same year four grain elevators went up at Mossleigh, operated by Searle Grain, Parrish & Heimbecker, Pioneer Grain, and the United Grain Growers. Three of those elevators still stand, one of the few remaining clusters of its kind on the prairies, and Aspen Crossing's trains pass historic wooden elevators on their regular runs. The railway's own promotional material leans into the setting, noting that the haunt sits one kilometre west of Mossleigh and 35 kilometres southeast of Calgary, and warning guests not to miss their turn because "these hills have eyes." The parking lot, in the event's telling, is an old cemetery covered in gravel, situated between the tavern and the station.
For all the theatrical menace, the practical details are ordinary. Admission prices vary by the time and date selected, and attendees who show up without a ticket can purchase stand-by rides at the venue if spots are available. Cancellations made 30 days before the departure date are eligible for a refund. Dining is available on site at the Bergquist House Tavern and at The Aspen Outpost just down the road, and reservations are recommended. Guests who want to make a night of it can stay in the railway's large RV campground or in one of three caboose cabins, converted from Union Pacific, Canadian Pacific, and Northern Alberta Railway cars, complete with a store, an ice cream shop, and delivery service right to the campsite.
It is a long way from a landscaping order for used railway ties. The line that Canadian Pacific was tearing out of the ground two decades ago now carries a Halloween attraction that draws people from across southern Alberta to be chased through the dark by strangers who are allowed to grab them. The train comes back to the station either way. Whether everyone on board is glad about that is, apparently, part of the point.
