MODEL INFORMATION
Company: Atlas O
Item #: 6333-1
Gauge: Standard O
Trucks: Die-Cast, Sprung
Notes: This hopper handles the 60" and 72" mainlines just fine, but the trucks hit the car on 36" curves. It is a large - a scale model if the couplers and trucks are converted, and it is made for easy 2-rail conversion.
PROTOTYPE INFORMATION
Car Manufacturer: ACF
Notes: An early design of what would become the highly successful "Center-Flow" car. Frisco had 25 of these cars: SL-SF 81000 thru SL-SF 81024. The cylindrical design was expensive to build. ACF soon modified their Center-Flow design into what has become a very common covered hopper in many sizes and capacities.
