Tank Car, Early, Wooden

History: The earliest version of tank cars, or the "oil car" as it was known then, began to appear in the early 1860s during the Civil War. Essentially, a standard flatcar was employed with two or three vertical vats placed on top. Unfortunately, the design had several flaws; the most obvious was that it could not hold much product due to height and width issues. Additionally, leaking was again an issue. By the late 1860s, following the war, the first true tank cars began to take shape. In this particular case the early vertical vat-on-flat-car design was changed to a horizontal iron tank, which was then mounted to a traditional flat car. The design was roughly similar to what is now commonly in service today, featuring a top dome (with safety valve) to load the product as well as a discharge valve at the bottom. It allowed for much more product to be shipped via one car and quickly found widespread use.
