Available On: May 1, 2026


Not to be confused with earlier AAR Double-Door Boxcars, the new WalthersMainline 50' AAR Double-Door Boxcar is based on a later prototype first built in the late 1940s and 1950s. These more modern cars featured improved Dreadnaught ends and metal Apex running boards. Wide double doors on each side allowed for easy loading and unloading of large cargo, such as lumber, building materials, appliances and more. These cars spent decades roaming the rails across the country.
With newly tooled double-door sides and other accurate details, the WalthersMainline model captures the look of its long-serving prototype. And like their prototypes, these durable models will provide years of reliable operation on your HO railroad.
Other features include:
- 4-3-1 “Improved” Dreadnaught ends
- AAR tab side sills
- Detailed underbody with AB brake equipment
- 7-rung side and end ladders
- Factory applied, separate Ajax hand brake
- Factory applied, separate Apex simulated metal running board with see-through tread
- Correct 33" RP-25 turned metal wheels in AAR Bettendorf trucks
