O CSX Tank Car #1776

Until the 1950s, the typical railroad tank car consisted of a tank
strapped to a full underframe, similar to the frames of most other
cars, and the maximum capacity was about 12,000 gallons. But in the
second half of the century, tank cars underwent a fundamental change as
the tank itself took on the dual role of carrying the load and
supporting the car. “Frameless” or stub-sill tank cars became the norm,
featuring larger-capacity tanks and just a stub frame at each end for
attaching the trucks.

Different designs evolved for different loads. One of the
most distinctive is the funnel flow car with its “bent in the middle”
shape, developed by the Union Tank Car Company (now UTLX Manufacturing
Inc.) in the 1960s. Designed for liquids that can be unloaded by
gravity (as opposed to pressurized unloading), the car is lower in the
middle so the tank acts like a funnel to facilitate unloading.

Our model replicates the shorter cars used for heavier
liquids. Funnel flow cars that haul thick liquids such as asphalt,
molten sulphur, and corn syrup also feature internal heating coils to
warm the contents for faster unloading. Other popular loads include
slurries – dry powders mixed with water to make them flow easier – of
kaolin clay bound for paper plants and calcium carbonate used to make
lime and cement. Other funnel flows serve the chemical industry. To
prevent contamination, many of these cars are in dedicated service for
one commodity or shipper.
