Atlas - 20 001 870 - Covered Hopper, 6-Bay, ACF Cylindrical - Alaska Railroad

Body Style Information: Introduced in 1961 by ACF® to haul sand, clay, salt, grain and bulk plastics, the Cylindrical Hopper was the first commercially successful tank-type covered hopper car design. A few of the more than 4,000 cars of this type built through 1966 can still be seen in service today across the United States.

Prototype Information: ACF introduced their roundish cylindrical hoppers in the early 1960s. The cars differed greatly from the ribbed sided hoppers of the era. They have been made in 3-bay and 6-bay variations. These cylindrical hoppers were superseded on ACF’s production line by the Centerflow in 1964, a revolutionary design that influenced later covered hopper types. In the late 60s or early 70s Canada came out with 4-bay covered hoppers that appear to be derived from ACF’s pre-Centerflow cylindrical hoppers. These cars were used by CN, CP and various smaller Canadian shippers. There is some question as to why the Canadian builder based their design off the older cylindrical and not ACF’s newer Centerflow. It was likely a patent issue and copying it could have triggered legal action against the Canadian builders. There are also certain structural design differences between the cylindrical and centerflow cars and perhaps the decision to copy the cylindrical was based on the greater volume capacity of the cylindrical design.

Road/Company Information: Born in 1923 with the consolidation and connection of the Tanana Valley and Alaska Northern railroads, the line was owned by the Federal Government (under the Department of the Interior) from the outset, later becoming the responsibility of the Department of Transportation in 1967. In the mid-80s it was sold to the State of Alaska.

The Alaska Railroad links Anchorage with the port of Whittier and Seward to the south, and Fairbanks and environs to the north. Total mileage is about 525 putting it between Bangor & Aroostook and New York Ontario & Western in relative size. Alaska does run its own passenger service over the length of the railroad. Although the Alaska Railroad is disconnected from the rest of the North American rail network, they do interchange with other railroads. A trio of sea-going barges ferry rail cars from the port of Whittier to Prince Rupert, British Columbia, and Seattle, Washington. ARR had collected a fleet of Alco RS-1s (and a few RSD-1’s) with cowls, effectively making them cab units unique to this line. These were later replaced by second generation EMD power. The big power on the line is a fleet of 28 SD70MACs. A dozen of these are equipped with HEP for use in passenger service.

The port of Whittier is hemmed in by the ocean on one side and mountains on the other. A 2.5 mile single track tunnel is the only way out of the port. The line through the tunnel is paved like street trackage so that highway traffic can use the tunnel. It is a single lane so highway traffic going south enters from the top of the hour until quarter after. Northbound traffic enters from the bottom of the hour until 45 after the hour. Trains get priority and proceed as soon as traffic has cleared.

Brand/Importer Information: In 1924 Stephan Schaffan, Sr. founded the Atlas Tool Company in Newark, New Jersey. In 1933 his son, Stephan Schaffan, Jr., came to work for his father at the age of sixteen. Steve Jr. built model airplanes as a hobby and frequented a local hobby shop. Being an enterprising young man, he would often ask the owner if there was anything he could do to earn some extra spending money. Tired of listening to his requests, the hobby-store owner threw some model railroad track parts his way and said, "Here, see if you can improve on this".

Atlas has made a ton of wonderful products throughout the years and we often get questions one whether we have run a certain road name on a particular model. It should be noted that Atlas locomotives and rolling stock are greatly appreciated for their superior operating and running characteristics. Atlas products are also well known for their outstanding collectability not only due to their superior prototypical workmanship, details and decoration, but because there are relatively so few of them made. Each and every production run has been carefully built to market demand, meaning almost every piece in any given run is sold out by Atlas on arrival or shortly thereafter, thus creating a built in collectors market.
