Thats how many H21 class hoppers were built by the Pennsylvania Railroad. To put that in some perspective, thats more cars in one class than the Missouri Pacific, Nickel Plate or Rock Island had cars of ALL types on their rosters! Put another way, through the 1950s one of every two PRR hoppers was an H21! This is a car that every modeler needs!
