In 1961, the Halliburton Company introduced a railcar designed to carry dry products such as dry cement, pozzolanic (an additive) and fly ash in bulk,
basic dry products for mixing drilling mud to control hydraulic conditions while drilling oil wells. The basic car was built by Pullman-Standard
with the tanks, tank supports, piping, running boards and ladders being fabricated and installed by Halliburton at the Duncan, Oklahoma shops.
The cars are numbered HWCX-50 through HWCX-124. These cars are still in use today I do believe.
