Welcome to the Halliburton (HWCX) Freight Cars Page. Halliburton is a well established oil field service company providing cementing services for land and offshore based drilling operations. They have rostered a variety of railcars in which they have shipped dry, bulk cement. They have had several varieties of two bay 70 ton covered hoppers in their colorful red, white and grey colors. They also have a fleet of hoppers featuring three vertical tanks to store cement. These are similar to the skid mounted units that are used to support offshore drilling operations commonly referred to as P-tanks. A subsidiary of Halliburton, IMCO (International Mud Co,) had a fleet of green and white covered hoppers also lettered with HWCX reporting marks. It is supposed that these cars were probably the former Halliburton cars. Some were eventually relettered with IMSX reporting marks. A two part article on building an HO model of the 3-tank hoppers, trucks and a transload facility appeared in the December 1983 and ???? issues of RMC magazine.
