Con-Cor - 0003-570003 - Passenger Car, Heavyweight - Baltimore & Ohio - 6 pack

Model Information: The Rivarossi passenger car sets typically came with an assortment of three cars. In many cases each of the three cars were a different body style, but in some cases, the same car might appear multiple times but with different road numbers. The duplicates were typically with coaches where this would be desirable. All three cars would be from the Rivarossi heavyweight series and all three carry the same road name and paint scheme.

Prototype History: Heavyweight Passenger Cars were the prevalent style of railcars used for passenger service during the interwar period. They were constructed of concrete, wood and steel. The floor was often of poured concrete, which helped give these cars a smoother ride than older wooden-body cars. Also, because of their heavy construction, they were also much less likely to "telescope" when a collision occurred. They were much heavier than modern passenger cars due to the materials used in their construction. They were so heavy that they often (but not always) required three-axle bogies to support them.

Heavyweights frequently had what is called a clerestory roof. The center of the roof was higher than the sides, in that it was stepped up. The lightweight cars had smooth, rounded roofs. Heavyweight passenger cars typically weigh around 1 ton per foot of length. So a 85' car weighs in the area of 85 tons for a heavyweight car.

Road Name History: The Baltimore and Ohio Railroad (reporting marks B&O, BO) is one of the oldest railroads in the United States and the first common carrier railroad. It came into being mostly because the city of Baltimore wanted to compete with the newly constructed Erie Canal (which served New York City) and another canal being proposed by Pennsylvania, which would have connected Philadelphia and Pittsburgh. At first this railroad was located entirely in the state of Maryland with an original line from the port of Baltimore west to Sandy Hook. At this point to continue westward, it had to cross into Virginia (now West Virginia) over the Potomac River, adjacent to the confluence of the Potomac and Shenandoah rivers. From there it passed through Virginia from Harpers Ferry to a point just west of the junction of Patterson Creek and the North Branch Potomac River where it crossed back into Maryland to reach Cumberland. From there it was extended to the Ohio River at Wheeling and a few years later also to Parkersburg, West Virginia.

It is now part of the CSX Transportation (CSX) network, and includes the oldest operational railroad bridge in the USA. The B&O also included the Leiper Railroad, the first permanent horse-drawn railroad in the U.S. In later years, B&O advertising carried the motto: "Linking 13 Great States with the Nation." Part of the B&O Railroad's immortality has come from being one of the four featured railroads on the U.S. version of the board game Monopoly, but it is the only railroad on the board which did not serve Atlantic City, New Jersey, directly.

When CSX established the B&O Railroad Museum as a separate entity from the corporation, some of the former B&O Mount Clare Shops in Baltimore, including the Mt. Clare roundhouse, were donated to the museum while the rest of the property was sold. The B&O Warehouse at the Camden Yards rail junction in Baltimore now dominates the view over the right-field wall at the Baltimore Orioles' current home, Oriole Park at Camden Yards.

At the end of 1970 B&O operated 5552 miles of road and 10449 miles of track, not including the Staten Island Rapid Transit (SIRT) or the Reading and its subsidiaries.

Brand/Importer Information: Con-Cor has been in business since 1962. Many things have changed over time as originally they were a complete manufacturing operation in the USA and at one time had upwards of 45 employees. They not only designed the models,but they also built their own molds, did injection molding, painting, printing and packaging on their models.

Currently, most of their manufacturing has been moved overseas and now they import 90% of their products as totally finished goods, or in finished components. They only do some incidental manufacturing today within the USA.

Important Note: The Con-Cor product numbering can be very confusing. Please see here in the article how to properly enter Con-Cor stock numbers in the TroveStar database.
