Tank Car 2-axle Z [P] "HOBUM" DB

Info about the original

By the end of the 1920s, the Deutsche Reichsbahn had completed its own development programme for standardised replaceable running gear. The wagon industry installed this running gear in countless wagons from 1928 onwards, which greatly simplified the subsequent installation of spare parts during vehicle maintenance and thus contributed to significant cost savings. Tank wagons with a capacity of 19.2 m³ were among the first types to use the new replacement components. These wagons were often used to transport various flammable liquids such as fuel oil, tar oils or vegetable oils. The many small orders received from a variety of customers and vehicle manufacturers resulted in numerous wagon variants that differed slightly in terms of the finer details. What they all had in common, however, was the use of a uniform undercarriage in a riveted design with a wheelbase of 4.5 m and a length over buffers of 8.8 m. Due to the limitations of welding technology circa 1928, most of the boilers were still produced using conventional rivet construction. Over 1,000 wagons were built between 1928 and 1938, the last of which remained in service in Germany until 1983.
