New Castle (CSX/NS)

New Castle offers a layered railfan experience centered on its role as a junction for multiple railroads in Lawrence County. The most accessible vantage point is the Mahoning Avenue Viaduct, a 1,195-foot-long steel truss bridge built in 1923–1924 that carries road traffic over the Shenango River and the railroad corridors below. From the viaduct's sidewalk, you look down on CSX and Norfolk Southern movements with an unobstructed overhead perspective uncommon for public viewing spots in western Pennsylvania.

At ground level, the CSX New Castle Yard — a former Baltimore & Ohio facility — sits in the Mahoningtown neighborhood, where CSX, Buffalo & Pittsburgh Railroad (BPRR), and New Castle Industrial Railroad (NCIR) trains exchange cars daily. The NCIR's three locomotives work 16 miles of track serving local industries, and watching their switching moves through the yard provides a close-up look at shortline railroading.

For a more immersive experience, the Stavich Bike Trail runs 12 miles from New Castle to Struthers, Ohio, on a paved path that shares the right-of-way with active CSX trackage along the former Pittsburgh & Lake Erie mainline. You are rarely out of sight of the railroad along this trail, making it one of the best rail-with-trail experiences in the northeastern United States.

New Castle sits in a shallow valley carved by the Shenango River in Lawrence County, about 50 miles northwest of Pittsburgh and 20 miles east of Youngstown, Ohio. The Shenango River and Neshannock Creek converge near the city center, and the railroad corridors thread through this river valley alongside remnants of New Castle's industrial past.

The visual character is distinctly Rust Belt: brick and stone mill buildings, weathered railroad infrastructure, and the massive steel spans of the Mahoning Avenue Viaduct frame the rail activity below. The viaduct itself, with its three Pennsylvania through-truss spans totaling over 800 feet across the river and tracks, is an impressive piece of early 20th-century engineering that replaced the Gardner Avenue Bridge destroyed in the catastrophic 1913 flood.

Along the Stavich Bike Trail to the west, the landscape opens into more rural terrain as the path follows the ex-P&LE right-of-way toward Ohio. The forested sections are particularly photogenic in autumn when the hardwood canopy turns, contrasting with the dark ballast and steel rail.

Three Class I and shortline/regional railroads operate through New Castle, making it one of the more diverse rail junctions in northwest Pennsylvania.

CSX Transportation operates the New Castle Subdivision (ex-Baltimore & Ohio Railroad, running west through Youngstown and Akron to Greenwich, Ohio) and the New Castle Terminal Subdivision (14.7 miles from West Pittsburg to New Castle). CSX maintains the New Castle Yard, a classification facility inherited from the B&O, where interchange traffic is sorted. Freight consists include mixed manifest, intermodal, and bulk commodity trains.

Norfolk Southern runs through freights on the Fort Wayne Line / New Castle District, passing just west of the CSX operations. NS movements include intermodal and general merchandise traffic on this corridor connecting the Pittsburgh area with points west.

New Castle Industrial Railroad (NCIR), a Class III shortline formed in 1991 and owned by the Berkley family, operates three locomotives over 16 miles of track. NCIR moves approximately 10,000 carloads annually, handling steel products, scrap metal, plastic pellets, fracking sand, road salt, and Kasgro specialty railcars. NCIR interchanges with CSX, Norfolk Southern, and the Buffalo & Pittsburgh Railroad (BPRR).

The Buffalo & Pittsburgh Railroad (BPRR), a Genesee & Wyoming regional carrier, also exchanges cars through the CSX yard. No passenger service operates through New Castle.

The Mahoning Avenue Viaduct is the signature photo location. This 1,195-foot bridge carries Mahoning Avenue over the Shenango River and the railroad tracks below, providing an elevated three-quarter overhead angle on passing trains. Morning light illuminates eastbound movements, while afternoon sun favors westbound consists. The viaduct has pedestrian sidewalks on both sides, allowing you to position for either direction.

The Stavich Bike Trail offers extended parallel trackside shooting along the ex-P&LE mainline (now CSX). The paved trail runs at grade level alongside the tracks for much of its 12-mile length from New Castle to Struthers, Ohio, providing clear sight lines for broadside and going-away shots. A 70-200mm zoom covers most compositions from the trail.

Near the CSX New Castle Yard in the Mahoningtown neighborhood, public roads offer views of yard switching and interchange operations. NCIR locomotives working the yard provide opportunities for shortline action shots against an industrial backdrop. The Shenango River railroad bridges — including one formerly used by the Buffalo, Rochester & Pittsburgh Railroad — add structural interest to compositions from the riverbank areas.

New Castle's railroad heritage runs deep, with at least six major railroads having operated through the city at their peak. The Pittsburgh & Lake Erie Railroad ("The Little Giant") opened the first line through New Castle in 1879, connecting Pittsburgh to Youngstown, Ohio. The Pittsburgh, Cleveland & Toledo Railroad extended tracks from New Castle to Youngstown and west toward Akron in 1884, and by 1887 the Pittsburgh & Western Railway leased these tracks for through service between Chicago and Philadelphia.

The Baltimore & Ohio Railroad took control of the Pittsburgh & Western by 1902, establishing the major yard complex at New Castle Junction in Taylor Township — the facility that evolved into today's CSX New Castle Yard. The B&O's route through New Castle was part of its mainline corridor to Chicago, and the junction was a bustling terminal for decades.

The Pennsylvania Railroad also served New Castle via its New Castle Branch, while the Buffalo, Rochester & Pittsburgh and Erie Railroad added further connections. At the junction's height, multiple railroads operated simultaneously, and these companies jointly financed the Mahoning Avenue Viaduct in 1923–1924 to carry road traffic over their tracks — the PRR, BR&P, B&O, and Erie all contributed to the project.

The Mahoningtown neighborhood grew directly around these rail operations, and the city's tinplate and steel manufacturing industries depended on rail service. The NCIR shortline, formed in 1991 by the Berkley family, carries on this industrial railroad tradition today.

New Castle stands out among northeastern railfan destinations for its concentration of railroad diversity in a compact, publicly accessible area. Within a few miles, you can observe CSX main line freight, Norfolk Southern through trains, NCIR shortline switching, and BPRR regional interchange — four different railroad operations visible from public roads and paths.

The Stavich Bike Trail is a genuinely rare asset: a 12-mile paved rail-with-trail that shares the right-of-way with active CSX trackage, allowing you to bike or walk alongside freight trains for an extended distance. Opened in 1983 with donations from the local Stavich family, it was an early example of rail-with-trail design and connects two states (Pennsylvania and Ohio). Few railfan spots anywhere offer this kind of prolonged, parallel access to an active main line.

The Mahoning Avenue Viaduct adds a dimension most junctions lack: an elevated, public overhead perspective on the tracks. The 1923 bridge is itself a photogenic subject, and the combination of river, industrial architecture, and multi-railroad action below creates compositions distinctive to this location.

For the historically minded railfan, New Castle is a living archive of railroad consolidation: P&LE, B&O, PRR, BR&P, and Erie tracks have been absorbed into today's CSX and NS operations, and the physical infrastructure — bridges, yard, alignments — preserves traces of each predecessor railroad.
