Bring Mexican interchange traffic to your HO layout with this Atlas 50' Postwar Single Door Boxcar in Ferrocarriles Nacionales de México (N de M) brown and white, road number 93259.

Ferrocarriles Nacionales de México, better known as N de M, was Mexico's state-owned railway system, running from 1903 until the railways were privatized around 2001. During World War II, the U.S. Railway Mission to Mexico helped rebuild the system and train its crews in American practices. By war's end the N de M had one of the more modern freight car fleets in North America, built to the same AAR standards as cars in the United States.

That standardization meant N de M boxcars traveled freely in interchange. They were a regular sight in U.S. freight trains, arriving through border gateways like Laredo and Eagle Pass, Texas. Adding one to a southwestern, Texas or transcontinental layout is a simple way to show traffic from south of the border.

About the Prototype

After World War II, railroads ordered large numbers of 50' AAR boxcars built to a standard design first widely used in the late 1940s. It was based on the original 1937 AAR design, updated with improved Dreadnaught ends and a diagonal-panel roof. These 50' boxcars were common on North American railroads well into the 1970s and 1980s, making this car a good fit for transition-era through late-1980s layouts.

Features

• N de M #93259 – brown with white lettering
• Separately applied ladders and grab irons
• Fully detailed underframe
• Free-rolling trucks with metal wheelsets
• Accurate printing and prototypical paint scheme
• Ready to run

Specs

• Scale: HO (1:87)

• Item #: 20 005 853
• Road name / number: N de M (Ferrocarriles Nacionales de México) #93259
• Car type: 50' Postwar AAR Single Door Boxcar

Atlas also produced a sister car in this run, N de M #93064 (20 005 852). Pair them for a realistic cut of cars.

Many stories about the Union Pacific Railroad have centered around its construction as part of the nation's first transcontinental rail line. One of the more famous stories concern the Plum Creek Raid, in which three UP employees were killed and a UP freight train was derailed by the Northern Cheyenne on August 7, 1867, near Plum Creek (now Lexington), Nebraska.

It is the best-known instance in which Native Americans successfully wrecked the "iron horse" during their struggle against the encroachment of the railroad on their tribal lands.The incident includes the unusual tale of UP employee William Thompson and his scalp. Noted railroad historian Thornton Waite looks at the many conflicting versions of events related to the incident, and how it has been been portrayed in the media over the past 150-plus years.

Bill Simon collaborated with Estes to design the Belt Object Survey Ship (B.O.S.S) over 40 years ago. This was a time when the introduction of nuclear and solar power revolutionized space flight technology.

This unique rocket, which was not initially intended to be a model rocket, has been eagerly awaited and is being released as a prototype for the first time. With the B.O.S.S. Rocket, you can experience the innovation of the past with the latest addition to Estes' Signature Series.

We matched the Belt Object Survey Ship (B.O.S.S) design with premium components for top quality. Our mission is to bring you the latest in the Estes Designer Series. The B.O.S.S. Rocket comes with a rare asymmetrical structure, featuring:

• One tail fin for increased stability and control during launch.
• Two engine pod assemblies for maximum thrust and performance.
• A large circular plate to provide additional stability and balance during flight.

Experience the beauty of space with Belt Object Survey Ship. This is a vivid testament to the ingenuity and creativity of the early space enthusiasts.
