Shooting
Principal photography began spring of 1985, at the Butte, Anaconda, & Pacific Roundhouse in Anaconda, Montana. During filming, the crew realized they didn't have any real snow, due to warm temperatures (a false spring) in the area. They used Christmas tree flocks for fake snow, and they had to keep it from melting on the tracks at the west yard. Cannon Films had to cut short its stay in Anaconda, and they moved onto Deer Lodge, Montana, to film the prison scenes at the Old Montana State Prison. Approximately 200 extras were hired to play prisoners in the scenes. They spent a week filming several scenes at the prison. Finally, the second unit team went to Whittier, Alaska, to film on the Alaska Railroad tracks. The Bridge sequence was filmed on the Seneca Bridge on Placer Creek, about 5 miles (8 km) from Whittier. The scene where the signal maintainer at Jordan makes the switch on the tracks was filmed at Portage, Alaska. The cast and crew went to the Pan-Pacific Auditorium in Los Angeles, to film the interior of the train scenes and the prisoners' escape scene.
The runaway train's lineup in the movie consisted of four Alaska Railroad locomotives, all built by EMD: GP40-2 #3010, F7 #1500, and #1801 and #1810, both GP7s. The latter two locomotives had previously been rebuilt by ARR with low short hoods as opposed to a GP7's original high short hood but were fitted with mock-up high hoods made of plywood for the film, branded with fictional numbers 531 and 812, respectively. Because #1801's cab had been reconstructed prior to filming, the '531' prosthetic hood stood slightly higher than the normal hood height of a GP7 to fit over the locomotive's number board.
The locomotives used in the film have gone their separate ways:
ARR GP40-2 #3010 is still active on the Alaska Railroad, painted in the new corporate scheme.
ARR F7 #1500 was retired from service in 1992, and is now at the Museum of Alaska Transportation and Industry Museum in Wasilla, Alaska, as can be seen on the front page of their website MuseumOfAlaska.org.
ARR GP7 #1810 was sold to the Oregon Pacific Railroad and operated as OP #1810. In 2008, the unit was sold to the Cimarron Valley Railroad and is now permanently coupled to former OP Slug #1010.
ARR GP7 #1801 was sold to a locomotive leasing company in Kansas City, Missouri, then sold to the Missouri Central Railroad and operated as MOC #1800. The locomotive subsequently appeared in another motion picture, Under Siege 2: Dark Territory, in 1995. MOC became the Central Midland Railroad in 2002. As Central Midland had its own leased power, MOC 1800 was returned to Midwest Locomotive In Kansas City. Shortly after, it was then sold to the Respondek Rail Corp of Granite City, Illinois, and is now used on Respondek's Port Harbor Railroad subsidiary. The unit's identification is RRC #1800. As of 2015, the locomotive has been stored, is out of service, needing wheelwork. A return to service on the Port Harbor Railroad is unlikely, as there is talk about sending the unit to another Respondek Operation.
The train that was hit by the runaway was led by MRS-1 #1605. This unit had been retired in 1984, one year before filming started. The unit has since been cut up for scrap.
Sequences set at the rail yard, shot on the Butte, Anaconda and Pacific Railway in Anaconda, Montana, used local locomotives from the BA&P fleet along with former Northern Pacific EMD F9 #7012A, leased from the Mount Rainier Scenic Railroad. The two GP7s and the F9 were fitted with plywood boxes to duplicate the distinctive 'winterization hatches' carried on their Alaskan counterparts.
BA&P EMD GP38-2 #109, the BA&P locomotive used in the yard scenes as the lead engine in place of ARR #3010, was subsequently sold to the Alaska Railroad and remains in service there as #2002, along with sister unit #2001 (ex-BA&P #108).
