Model Information: First released in 1972, this series of covered hoppers approximates ACF's 1964 centerflow model. The carry Bachmann's typical (of that time) features: nickel-silver plated deep flange wheels and Rapido couplers. The 1972 Bachmann catalog shows seven different road names listed at $2.50 each.

Prototype History: Contemporary 2-bay covered hoppers, like ACF's Centerflows, were 100-ton cars designed to haul dense loads, like cement. Their larger 3 and 4-bay brethren, while usually still having 100 ton capacities, were designed for lighter-density loads, like grain or flour. Their sizes had to do with the fact that a low-density product like grain will "cube out" the cubic capacity of a smaller 2-bay car way before you hit the cars' tonnage rating. Conversely, load a 3 or 4-bay covered hopper to its cubic maximum with a dense product like cement, and you'll wind up with a seriously overloaded car tonnage wise. In short, keep the smaller 2-bay cars for heavy commodities, and keep the larger cars for lighter loads like grains, sugar, flour, etc.

Road Name History: The Lehigh Valley Railroad (reporting mark LV) was one of a number of railroads built in the northeastern United States primarily to haul anthracite coal. It was authorized April 21, 1846 in the U.S. state of Pennsylvania and incorporated/established on September 20, 1847 as the Delaware, Lehigh, Schuylkill and Susquehanna Railroad Company. On January 7, 1853, the name was changed to Lehigh Valley Railroad. It was sometimes known as the Route of the Black Diamond, named after the anthracite it transported. At the time, anthracite was transported by boat down the Lehigh River; the railroad was meant to be faster transportation. The railroad ended operations in 1976 and merged into Conrail that same year.

During its existence, the Lehigh Valley Railroad used a rail line that later became known as the Lehigh Line in order for it to operate. The Lehigh Line was the railroad's first rail line constructed which was built in 1855 between Easton, Pennsylvania and Allentown, Pennsylvania and it served as the main line for the Lehigh Valley Railroad. Serving as the main line for the Lehigh Valley Railroad, the rail line expanded past Allentown to Buffalo, New York and past Easton to New York City, bringing the Lehigh Valley Railroad to these metro areas. During the early years, the line served as the body of the Lehigh Valley Railroad until the railroad either built more rail lines or railroads, acquired more rail lines or railroads, and merged other railroads into their system. The line was known as the Lehigh Valley Mainline during the majority of its time under the ownership of the Lehigh Valley Railroad, starting in the 1930s. The "Lehigh Valley" was absorbed along with several northeastern rail lines into Conrail; the main line became known as the Lehigh Line during the Conrail ownership. Conrail shortened the track miles by abandoning most of its route to Buffalo and some of the line entering New York City area. The Lehigh Line is now owned by the Norfolk Southern Railway.

As of 31 Dec 1925, 1363.7 miles of road, 3533.3 miles of track; as of 31 Dec 1970, 927 miles of road and 1963 miles of track.
