Gondolas have been used since the early 1900s to transport a variety of bulk materials. Thanks to their low sidewalls, gondolas are suitable for a wide range of cargo, from steel plates to ballast, coils, scrap metal, and more bulky items such as track segments. Based on a popular steel gondola design first appearing on railroads in the late 1920s, the Bachmann 40' Gondola comes in a variety of authentic railroad colors appropriate for a wide range of eras. Bachmann's track cleaning car provides an efficient and economical way to clean your track. This car's exclusive dry cleaning system features a reusable track cleaning pad. Track Cleaning Replacement Pads, Item 16949, also available.
