Atlas 50007345 - ACFX / Montana Talc Company

A part of ACF’s Centerflow line, the 5,000 cubic foot Pressureaide hopper was designed to handle dry, powdered commodities like flour. Due to its similarity to ACF’s popular 4650 cubic foot Centerflow hopper, the Pressureaide hopper benefit from the 4650’s similar design, with one major difference being various pipes running underneath the car. 15psi is applied to the inside of the piping to help with unloading. These cars debuted in the late 1970s and were built until the 1990s and paved the way for more pressure-assisted hopper cars. These cars are still commonly seen in service in the modern day.
