The name "gondola" actually predates railroads. In the early 1800s, utilitarian flat-bottomed boats with low sides, used to transport coal down the Potomac River to the Washington D.C. area, were called gondolas as a spoof on the much fancier Venetian gondolas. Similarly shaped coal-carrying cars on early railroads earned the same moniker. As more specialized cars were invented for coal service, the gondola evolved into the general-purpose car it is today.
