Troy is a historic city located in upstate New York, situated on the eastern bank of the Hudson River. The city was founded in the late 18th century and quickly became an important industrial center, particularly in the iron and steel industries. Troy's location on the Hudson River made it a key transportation hub for the region, with goods being transported by both water and rail. The city's proximity to major trade routes and its access to the Erie Canal helped fuel its growth and prosperity.

One of the most notable features of Troy's transportation history is the Troy Union Railroad. This railroad, established in the mid-19th century, connected the various industrial areas of the city and played a crucial role in the transportation of freight. The Troy Union Railroad had an extensive network of tracks that reached all corners of the city, allowing for efficient movement of goods between factories and the riverfront. Today, the railroad tracks have been repurposed into a recreational trail known as the Uncle Sam Bikeway, providing residents and visitors with a scenic route for walking, running, and cycling.

Altoona, PA is a city located in Blair County, Pennsylvania. It is known for its rich history in the railroad industry, particularly as the home of the Altoona Works, one of the largest railroad repair facilities in the world. The Altoona Works was established in 1850 by the Pennsylvania Railroad and played a pivotal role in the development of the American rail system. Today, the city still maintains strong ties to the railroad industry, with Norfolk Southern's Juniata Locomotive Shop being one of the largest employers in the area.

One of the most notable features of Altoona is the Horseshoe Curve, a famous landmark in American railroad history. Built in 1854, the Horseshoe Curve is a three-track railroad curve that spans 2,375 feet and rises 139 feet. It was a remarkable engineering feat at the time and allowed trains to navigate the steep Allegheny Mountains more efficiently. The Horseshoe Curve is still in use today and is a popular tourist attraction, offering visitors a chance to witness the impressive sight of trains navigating the curve.

In addition to its railroad heritage, Altoona is also home to the Railroaders Memorial Museum, which showcases the history and impact of the railroad industry on American society. The museum features a collection of locomotives, rolling stock, and exhibits that highlight the lives of the men and women who worked on the railroads. It is a must-visit destination for anyone interested in the history of transportation and the role of railroads in shaping the United States.
