The Allegheny Portage Railroad was the first railroad constructed through the Allegheny Mountains in central Pennsylvania. It operated from 1834 to 1854 as the first transportation infrastructure through the gaps of the Allegheny that connected the midwest to the eastern seaboard across the barrier range of the Allegheny Front. Approximately 36 miles (58 km) long overall, both ends connected to the Pennsylvania Canal, and the system was primarily used as a portage railway, hauling river boats and barges over the divide between the Ohio and the Susquehanna Rivers. Today, the remains of the railroad are preserved within the Allegheny Portage Railroad National Historic Site operated by the National Park Service.

The Middlefield–Becket Stone Arch Railroad Bridge District is a historic district extending through parts of the towns of Chester, Middlefield, and Becket, Massachusetts. The district encompasses a 3.7-mile (6.0 km) stretch of railroad right of way in which there are ten bridge crossings, including nine over the west branch of the Westfield River. The bridges were built in four time periods: 1840, 1866, 1912, and 1928. Nine of the ten bridges are stone or concrete masonry work, and one is a truss girder bridge. All are, with only minor exceptions, in excellent and original condition. The bridges were built to carry the Western Railroad through on its run from the Connecticut River to the Hudson River. This section of railroad was the most expensive the company had to build, costing over $1 million in 1840.

PRR shortened the viaduct and replaced the remaining wooden trusses with iron Whipple trusses in 1863.
