Well car - News - Business News

<p>HistorySouthern Pacific Railroad (SP), along with Malcom McLean, came up with the idea of the first double-stack intermodal car in 1977. SP then designed the first car with ACF Industries that same year. At first it was slow to become an industry standard, then in 1984 American President Lines, started working with the SP and that same year, the first all "double stack" train left Los Angeles, California for South Kearny, New Jersey, under the name of "Stacktrain" rail service. Along the way the train transferred from the SP to Conrail. Multiple unit carsA multi-unit articulated double-stack car, with five 48' wells. This one was built by Thrall and is owned by Pacer Stacktrain. Note that there is no bottom, which would make it unsuitable to carry road trailers.Double-stack cars may be constructed with a single well, but are often constructed with multiple units, usually with 3 or 5 wells, connected by articulated joints. Articulated joints are supported by a single truck,
(often a 125-ton capacity truck).Also, in a number of cases, multiple single-well cars (usually 3 or 5) are connected by drawbars and share a single reporting mark.On both types of multiple-unit cars, the units are typically distinguished by letters, with the unit on one end being the "A" unit, and the unit on the other end being the "B" unit. Middle units are labeled starting with "C", and going up to "E" for five-unit cars. Carrying capacityDouble-stack cars come in a number of sizes, related to the standard sizes of the containers they are designed to carry. Well lengths of 40ft (12.19m), 48ft (14.63m) and 53ft (16.15m) are most common. A number of 45ft (13.72m) wells and 56ft (17.07m) wells also exist. (The sizes of wells are frequently marked in large letters on the sides of cars to assist yard workers in locating suitable equipment for freight loads.)In cases where wells are smaller than some of the containers being loaded, larger containers are often placed on top of
smaller containers that fit in the available wells. Many wells are also capable of carrying two 20' ISO containers in the bottom position.Some double-stack cars have been also equipped with hitches which allow them to carry semi-trailers as well as containers. These are known as "all-purpose" well cars. Other countries Australia - double stack trains operate between Perth, Adelaide, Darwin and Parkes, NSW 6.5m (21ft) clearances India - Mundra Port operates double stack diesel trains on 1,676 mm(5 ft6in) gauge using flatcars. It is one of only 3 countries to commercially double stack 9ft6in (2.9m) tall containers on a train. Experiments for double stacking under 25 kV AC overhead lines have begun because of funds given by Japan. China - using double stacked container trains under 25 kV AC overhead lines. Choke pointsLow bridges and narrow tunnels in various locations prevent the operation of double-stack trains until costly upgrades are made. Some Class I railroad compani
es in the U.S. have recently initiated improvement programs to remove obstructions to double-stack trains. See Heartland Corridor (Norfolk Southern Railway) and National Gateway (CSX Transportation).
