Sold out!

General American Transportation Corporation produced more than 5,000 of these 4180 cubic foot Airslide covered hoppers between 1963 and 1980 as a response to customer demand for larger covered hoppers capable of handling bulk commodities. These very common cars continued General American’s “Airslide” family innovations from the 1950s, and proved valuable to bulk shippers who wanted a larger car than the earlier-design 2600 cubic foot cars provided.

The Tangent Scale Models GA 4180 Airslide covered hopper is similar to previous Tangent releases with our consistent focus on phase variations that mirror prototype build changes over time. For this car, we have produced three very different variations of the carbody and associated details to replicate cars built between 1965 and 1980. While all 4180 airslides may look the same at first glance, they are not. See the listing of phase details below for more information.

These models include the distinctive “see through” bolster arrangements above the trucks. These 4180 Airslide hoppers include finely-detailed underframe pipe arrangements and are ready for any of the following services on your layout: flour, sugar, starch, fertilizer, feed, chemicals, plastics, carbon black, etc. Also, check out the correct “true-to-life” colors and “hyper-accurate” lettering including exact fonts and lettering placement. These scale replicas operate as well as they look, equipped with free-rolling all-metal wheels and Kadee® scale couplers, meaning our models are truly ready to run, but look significantly better than train set alternatives.

Features for these replicas include:

– Dimensional accuracy – designed from General American plans and verified with field measurements

– Highly correct “true to life” colors

– “Hyper-Accurate” lettering including exact fonts and lettering placement

– Genuine Kadee® scale couplers

– “Near-scale” draft gear box with beautifully-rendered side “key” detail

– Multiple road numbers for each scheme

– “See through” etched metal running boards

– 3 specific production variations that highlight production from 1965-1980, including different roofs, running boards (Apex or Morton), body side post (“rib”) profiles, high and low brake arrangements on the B end, different ladder and grab iron arrangements, with or without crossover platforms and handrails, etc. Sell off the toy trains – we do freight cars right.

– Lacy details – wire grab irons and coupler lift bars

– Separate air hoses

– CNC-machined 36” wheels in high quality Tangent Scale Models trucks, with semi-scale wheels available separately

– Recommended age 14 years and older


GM&O “Original Gray 1966″ is offered in the original gray scheme from 1966 with the classic “Gulf, Mobile, and Ohio” spelled out on the carbody. Like many of the 4180 airslides, GM&O’s cars were in pooled service and were loaded at offline origin stations, one of which was stenciled on the sides of the car. This run includes prototypically-accurate return route stencils in highly visible red lettering for one of several loading points: MPRR Atchison KS (car #85028 and #85035). These are pooled cars, so be sure to add one to your MP layout!
