1921 Mack AC Railbus (S scale)
Built by Mack Trucks, the AC model was a versatile railbus used for passenger service. The 1921-built Mack Model AC railbus featured a 64 horsepower, 4-cylinder gasoline engine and had a seating capacity of 35 passengers. Mack Trucks was a pioneer in the railbus industry, producing various models that served both rural and urban areas. Their railbuses were known for their efficiency and versatility, with bodies often built by companies like the J.G. Brill Company
This S-scale version is a customer-requested upscaled version of a model created in N scale.
A link is included to the N-scale instructions for information only. The kit includes 3D printed resin body and roof. The builder will need to source and supply the power chassis, front four-wheel truck, LED lamps, brass wire, screws, clear glazing material, paint and decals. Care must be taken as some parts such as headlights, marker lights, and steps are fragile.

Just got my railbus in today after much anticipation. Wonderful model with great detail, and the print quality is perfect. Can't wait to get it powered and running!
Made-to-Order Manufacturing
At 3DPT, every model is manufactured to order rather than pulled from warehouse inventory. This approach allows us to offer an extensive catalog while ensuring each piece is produced with the care and attention it deserves.
Most orders ship within 7-14 business days. However, larger models, complex projects, and high-volume orders may require 4-6 weeks or longer due to extended print times and production requirements.
While extended lead times are uncommon, they may occasionally occur during periods of high demand or due to circumstances outside our control. We appreciate your understanding as we continue our mission of preserving transportation history in miniature through high-quality, made-to-order models.
