During the 1960s, railcar builders experimented with new covered hopper designs to satisfy the evolving needs of shippers as they moved away from forty-foot box cars to bulk transport railcars. During the 1963-1966 period, General American Transportation Corporation (GATC) produced its first “grain hopper” design as a 4500 cubic foot capacity prototype, selling more than 1,200 cars to a variety of railroads and lessors. The design had two distinct exterior appearances, with either 13 or 15 exterior side posts. The 4500 had a sister car design, of 4700 cubic feet, which looked similar because it had the same side post variations, however it utilized a 5-inch taller design.

These prototypes were originally bought by a handful of railroads, in several versions! First up is the ATSF, CGW, CRDX version, which featured a 13-post body with body-mounted brake details. The ATSF cars were originally delivered in 1966. The ATSF refurbished their GATC 4500s in the early 1980s and removed the distinctive General American rooftop ribs. This rebuilt roof includes an accurate Morton style running board with that distinctive Uni-wing flange. Along with its roof changes, the car lost its original frame-style Wine outlet gates. If you look carefully, you will notice the updated, accurate Miner outlet gates with “Selflok” mechanisms. The ATSF’s GATC cars featured a 13-post body, body-mounted brake hardware, and linkage below the underframe. The B-end has as accurate Klasing 1150 hand brake, modern brake wheel, Morton brake step and lowered retainer valve. The Santa Fe GA-159 covered hopper is painted in Topeka Shops-applied oxide red with “Quality” logo graphics for the 1991+ era.

Aside from railroads, some GATC 4500s were leased by lessors to shippers. ADM leased GATC 4500 from Chicago Freight Car Leasing Company (CRDX) and they were painted in a ADM dark blue with white graphics. These CRDX prototypes had Morton roof walkways and body mounted brake gear. Look closely at the bays, and you will notice the distinctive Wine “Combo” style outlet gates that allowed for either normal gravity unloading or low pressure air-assisted pneumatic unloading depending on the commodity. The B-end features a Morton brake step and Ajax power brake. The low retainer valve is mounted near the air reservoir, just like the prototype.

The second GATC 4500 body type is the 15-post body with truck-mounted brake details and is appropriate for the CB&Q, C&S and FW&D prototypes.  The January 1965 delivery of GATC 4500s to CB&Q was the CB&Q’s second order of cars from General American. These 400 cars were delivered in the Q’s classic covered hopper gray with Chinese Red graphics and featured a herald applied to a stand-off metal plate across the ribs. One of the neat details of this scheme is the large General American triangle logo painted on the far left of the body, with a red background specific to the CB&Q. The black bays and underframe are a classy touch. The Q’s cars were built with the 15-post body style with an Apex walkway and a high-mount retainer on the B-End. The prototype’s truck-mounted brake gear translates to little details such as the 4 individual brake cylinders that are actually mounted on the truck brake beams. These cars were delivered with the Wine outlet gates and their distinctive frame mounting plus accurate gear housing mechanism on the one side. The CB&Q was one of the largest owners of the GATC 4500, and they lasted into the 1990s BN!

CGW was also a buyer of these, delivered in the “Lucky Strike” paint scheme. The Chicago Great Western took delivery of 50 cars from GATC and they featured the 13-post body along with an Apex walkway. The ends of the CGW replicas have the long grab irons on the right side, body mounted brake details, a Morton brake step and a low-mounted retainer valve. Check out that beautiful Equipco power brake behind the modern brake wheel! Underneath the car, you can spot the Miner outlet gates with support brackets and underframe brake linkage. These cars were equipped with 100-ton Barber S-2 trucks and Brenco-6 style rotating caps! The CGW GATC 4500 prototypes lasted into the CNW and the UP eras, where these cars were used with their larger covered hopper fleets.

The third GATC 4500 body type is the 15-post body with body-mounted brake details and is appropriate for the EL, GN and N&W prototypes. We have materials to show this carbody, however we will save that for later when we release that version!

The Tangent Scale Models GA 4500 covered hopper system is a dimensionally-accurate replica of the real car, designed from actual blueprints and field measurements. Our system includes key build variations for the 4500 cubic foot design: body side post designs, running boards, roofs, roof hatches, discharge gates, high or low handbrake mounting and appliance options, and body or truck mounted brakes. This replica includes our “near-scale” draft gear box including side “key” detail. This GATC hopper rides on Tangent’s precision 100-ton Barber S-2 trucks with prototype-specific rotating bearing caps and separate brake beam part. Our ready-to-operate replica is finished with real metal grab irons, coupler lift bars accompanying Kadee® scale couplers, sufficient hidden weights, and CNC-machined wheels to ensure the model operates as good as it looks.

Our March 2023 debut includes four railroad schemes, plus three undecorated kit options.

– ATSF “Quality Repaint 1991” is a great example of a later-era GATC 4500.  The ATSF refurbished their GATC 4500s in the early 1980s and removed the distinctive General American rooftop ribs.  We have carefully duplicated this rebuilt roof with this offering, including an accurate Morton style running board with that distinctive Uni-wing flange.  We didn’t stop there.  Along with its roof changes, the car lost its original frame-style Wine outlet gates.  If you look carefully, you will notice the updated, accurate Miner outlet gates with “Selflok” mechanisms on the model.  The ATSF’s prototype GATC cars featured a 13-post body, body-mounted brake hardware and linkage below the underframe, all features that are present on this Tangent replica.  The B-end has as accurate Klasing 1150 hand brake, modern brake wheel, Moton brake step and lowered retainer valve.  Check out those gorgeous 100-ton Barber S-2 trucks with proper body-style brake beam and rotating Timken caps!   The Santa Fe GA-159 covered hopper is painted in Topeka Shops-applied oxide red with “Quality” logo graphics for the 1991+ era.  This modern example of Santa Fe railroading is available in 6 numbers!  SKU 28010 Scroll up and click the image at right to order!

– CB&Q “Delivery Gray 1-1965” replicates the CB&Q’s second order of cars from General American.  These 400 cars were delivered in the Q’s classic covered hopper gray with Chinese Red graphics and featured a herald applied to a stand-off plate across the ribs.  One of the neat details of this scheme is the large General American triangle logo painted on the far left of the body, carefully duplicated on the Tangent model with the correct red background specific to the CB&Q.  Of course, those black bays and underframe are a classy touch.  The Q’s cars were built with the 15-post body style with an Apex walkway and a high-mount retainer on the B-End.  The prototype’s truck-mounted brake gear translates to little things on the model like a “missing” brake cylinder on the B-End.  The 4 individual brake cylinders are actually mounted on the truck brake beams, duplicated on the 100-ton Barber S-2 trucks!  Take your time and enjoy the Wine outlet gates and their distinctive frame mounting plus accurate gear housing mechanism on the one side.  The CB&Q was one of the largest owners of the GATC 4500, and these cars lasted in CB&Q paint into the 1990s!  This all-new Tangent model is available in 12 numbers!  SKU 28011 Scroll up and click the image at right to order!

– CGW “Delivery Gray 9-1966” shows off the “Lucky Strike” paint scheme that has made the CGW one of our most popular roadnames.  The Chicago Great Western took delivery of 50 cars from GATC and they featured the 13-post body along with an Apex walkway.  The ends of the CGW replicas have the correct long grab irons on the right side, body mounted brake details, a Morton brake step and a low-mounted retainer valve.  Check out that beautiful Equipco power brake behind the modern brake wheel!  Underneath the car, you can spot the Miner outlet gates with support brackets and underframe brake linkage.  The Tangent model is equipped with 100-ton Barber S-2 trucks and proper Brenco-6 style rotating caps!  The CGW GATC 4500 prototypes lasted into the CNW and the UP eras, where these cars were used with their larger covered hopper fleets.  We proudly offer these CGW replicas in 12 road numbers.  SKU 28012 Scroll up and click the image at right to order!

– CRDX “ADM Blue Lease 9-1966” is one of those schemes that defines the word “sharp.”  ADM leased these cars from Chicago Freight Car Leasing Company (CRDX) and they were painted in a wonderful ADM dark blue with white graphics.  These models duplicate the CRDX prototypes with Morton roof walkways and body mounted brake gear.  Look closely at the bays, and you will notice the distinctive Wine “Combo” style outlet gates that allowed for either normal gravity unloading or low pressure air-assisted pneumatic unloading depending on the commodity.  The B-end features an accurate Morton brake step and Ajax power brake.  The low retainer valve is mounted near the air reservoir, just like the prototype.  The black 100-ton Barber S-2 trucks have accurate rotating Timken bearing caps.  This scheme is available in 6 numbers.  SKU 28013 Scroll up and click the image at right to order!
