The Baltimore & Ohio wagontop hoppers are rounded up and heading out. These transition-era covered hoppers are now available from Spring Mills Depot.
The B&O built a series of wagontop cars between the world wars. These home-built cars had at least two purposes: keep the shops busy during the Great Depression, and solve the problem of water infiltration on house cars. In addition to the class N-34 covered hoppers, the B&O also built cabooses and boxcars using similar construction techniques.
