Model Information: This model was first released in 2012 and is a completely new tooling. It replaced the earlier Bachmann 3-Dome tank car which dated back to the 1960s. The new ones can be distinguished most easily by the presence of pressure release valves on the sides of each of the three domes. This newer version also sport blackened metal wheels and EZ-Mate II knuckle couplers.
Prototype History:
Triple Dome tank cars, while not as common as single-domes, are a railroad staple. They have been around since the first half of the 20th century.

The dome above tank cars serves as an expansion chamber as temperature affects the volume of any liquids contained within. With no dome, if the liquid did not 100% fill the tank, then it is possible for the liquid to slosh around inside the tank, causing instability and increasing the possibility of a derailment. The dome allows the tank to be slightly overfilled so that should the volume in the main section decrease due to colder temperatures or even a small leak, that there will still be sufficient liquid within to prevent sloshing. Similarly if temperature increases, the liquid can rise up inside the dome preventing excess pressure within the tank. While not as serious as an underfilled tank, an over-pressurized tank might present problems during unloading.

If you see three domes on a tank car it is because there are three separate compartments inside the tank car each containing a different liquid. This was desirable for many reasons.

Often times a delivery would consist of much less than a carload (LCL) of liquid. Remember the sloshing problem? So if you only had to fill a third of a tank with your commodity, then you can avoid the issue by using one of the three chambers within the tank car. Also, you might have several grades of a commodity to deliver such as unleaded, leaded and diesel fuel and you need them to be kept separate. Or you might be producing wine and you want your white wine kept separate from your red wine. Or maybe all three chambers had the same contents but were being delivered to three different customers. It can be very difficult to determine when one third of a single dome tank car has been discharged...

For all these reasons, three-dome tank cars were a common sight in the first half of the 20th century. However, with the rise of the interstate highway system and the modern trucking industry, LCL deliveries have primarily been accomplished with tanker trucks instead of tank cars and the three-dome tank car has gradually disappeared from the North American rail network.
Road Name History:
Union Tank Car Company or UTLX (their best known reporting mark) is a railway equipment leasing company (and car maintenance / manufacturing) headquartered in metro Chicago, Illinois. As the name says, they specialise in tank cars, and covered hopper cars. As of September 2005, according to their site, they have about 80,000 cars in their fleet.

Union Tank Car Company was founded in 1866 by Captain Jacob J. Vandergrift, in response to the economic activities of John D. Rockefeller in the years leading up to his creation of Standard Oil. Vandergrift was involved in the conflicts in the oil regions of Western Pennsylvania in the 1860s?1870s. Eventually, Union Tank Car Company and Vandergrift's other holdings, which included pipeline and riverboat transport companies, merged with the company that later became Standard Oil. Rockefeller, once Captain Vandergrift's nemesis, made him Vice President of Standard Oil. The town of Vandergrift, Pennsylvania, built in 1895 by steel company president George G. McMurtry to house his workers, was named in Vandergrift's honor.

TransUnion was formed as a holding company in 1968 to hold Union Tank Car Company. TransUnion soon began began acquiring credit information and information management companies as a second major investment. The Marmon Group acquired TransUnion in 1981, spinning off the TransUnion name and the financial portion of the holding company to Madison Dearborn Partners in the 1990s.

Union Tank Car Company is still owned by Marmon, which in turn is now a 100% owned subsidiary of Berkshire Hathaway.
