History timeline 1865 flats with banded wooden tanks mounted on top are employed for the first time to transport crude oil from the fields of pennsylvania during the pennsylvanian oil rush 1869

capacities ranging from 6 000 160 us 160 gal 22 712 160 l 4 996 160 imp gal to 10 000 160 us 160 gal 37 854 160 l 8 327 160 imp gal 1903 tank companies develop construction safety standards more than 10 000 tank s are in operation 1915 a classification system is developed by the tank industry to ensure the correct match of product being shipped to type some 50 000 tank s are in use 1920 welding technology replaces riveting in tank construction enhancing the safety of s 1930 140 000 tank s transport some 103 commodities in addition to oil to market 1940s virtually every tank is engaged in oil transport in support of the war effort 1950 pipelines and tanker trucks begin to compete for liquid transport business 1963 the union tank company utlx introduces the whale belly tank usage many variants exist due to the wide variety of liquids and gases that can be transported tank s can be insulated or non insulated pressurized or non pressurized and designed for single or multiple loads non pressurized s have plumbing at the bottom for unloading and may have an access port and a dome housing various valving on the top pressurized s have a pressure plate with all valving and a protective cylindrical housing dome at the top loading and unloading are done through this opening tank s are specialized pieces of equipment with the interior of the is usually lined with a material to isolate the s structure from the contents such as glass loading a liquid into a that is designed to ry something else is unwise and sometimes dangerous even after a thorough cleaning traces of the previous contents may remain potentially contaminating the next load also loading a tank with something it is not designed to ry may actually damage the for example if the contents are corrosive as a result of this specialization tank s have always been one way s other s like box s can easily be reloaded with other goods for the return trip combinations of the two types were attempted such as box s with fluid tanks slung beneath the floors while the could certainly ry a load both directions the limited size of the tanks made this style unsuccessful because of their one way nature tank s are simply dead weight half of the time making them unappealing to major railroads a large percentage of tank s are owned by companies serviced by railroads instead of the railroads themselves this can be verified by examining the reporting marks on the s these marks invariably end in x meaning that the owner is not a common rier within the rail industry tank s are grouped by their interior linings and not by the go ried food service tank s are lined with stainless steel glass or cleanable plastic and they are marked as non pressurized insulated s usually these are small and ry around 10 000 160 us

rubber or coated with specialized coatings for tank protection or product purity purpose they are insulated usually non pressurized s however very light petrochemicals or jet fuel s will be padded with nitrogen to remove the air in the vapor space these s are larger around 23 000 160 us 160 gal 87 064 160 l 19 152 160 imp gal the ends will be doubled to prevent ruptures during accidents natural

type is giving way to higher but standard width s all tank s undergo periodic inspection for damage and corrosion pressure relief valves and mounts are inspected at every loading pressurized s are pressure tested regularly to insure the integrity of the tank all tank s operating throughout north america today feature double shelf aar type f couplers that prevent disengaging in event of an accident or derailment this prevents couplers and drawheads from puncturing adjacent tank s insulated s which may also incorporate heating or refrigeration systems are used when the contents must be kept at a certain temperature for example the linde tank depicted below ries liquefied argon s designed for multiple loads have internal bulkheads to separate the contents each compartment must have separate plumbing and its own dome if so equipped the added complexity of multiple load s means that they make up a small percentage of the tank population if two loads must be transported it is often simpler to use two tank s instead of a two load outside of north america they are also known as tank wagons or tanker wagons specialized applications milk s a milk is a specialized type of tank designed to ry raw milk between farms creameries and processing plants milk is now commonly chilled before loading and transported in a glass lined tank such s are often placarded food service use only liquid hydrogen s of this type are designed to carry cryogenic liquid hydrogen lh2 north american cars are classified as dot113 aar204w and aar204xt pickle cars a pickle car was a specialized type of designed to carry pickles this car consisted of several wooden or metal vats typically three or four and was often roofed pickles which are preserved in salt brine were loaded through hatches in the roof tanktainers type of shipping containers mounted on a flatbed railroad car tanktainer left and a open top shipping container with canvas cover right a tanktainer also known as a tank container is a specialized type of container designed to carry bulk liquids as with the liquid hydrogen tanktainer or dangerous goods on standard intermodal equipment the tank is held within a box shaped frame the same size and shape as a container torpedo cars a torpedo car or bottle car is a type of railroad car used in steel mills to haul molten pig iron from the blast furnace to begin the process of primary steelmaking the thermally insulated vessel is mounted on trunnions and designed to endure extremely high temperatures as well as keeping the metal in a molten state over extended periods of time the vessel can be pivoted along its longitudinal axis to empty the pig iron into a furnace such as a basic oxygen furnace or crucible vinegar cars a vinegar car is a specialized type of designed to transport vinegar the largest such car built was built by morrison railway supply corporation in 1968 the car s underframe included all of the modern conveniences of freight car design including roller bearing trucks and cushioning devices built by freightmaster while the tank that rode on it made of douglas fir had a capacity of 17 100 160 us gallons 64 731 160 l 14 239 160 imp 160

the union company utlx introduced a series of whale belly s which offered increased capacity over the standard cars of the day capable of carrying 33 000 160 us 160 gallons 124 919 160 l 27 478 160
