Memphis (CN/CSX Junction)

Kentucky Street interlocking is one of the premier urban railfan locations in the mid-South. This is the point where the BNSF Thayer Subdivision (ex-Frisco), the UP Memphis Subdivision (ex-Missouri Pacific), and the CSX Memphis Terminal Subdivision all cross the CN Memphis Subdivision (ex-Illinois Central) at grade. The result is a flat diamond crossing that sees movements from multiple Class I carriers throughout the day.

Memphis is one of only four cities in the United States served by five Class I railroads — CN, BNSF, UP, CSX, and Norfolk Southern — and Kentucky Street is where much of that traffic converges before funneling west toward the Harahan Bridge and the Mississippi River crossing into Arkansas. Railfans gather at the dead-end of Kentucky Street, which provides close, legal access to the tracks without trespassing. The location is not elevated, but sight lines are open in all four directions along the rail corridors.

Expect a mix of intermodal double-stacks, manifest freight, unit grain trains, auto-racks, and the occasional military movement. CN's Harrison Yard, located a few miles south, handles more than 35 freight trains daily with a capacity of over 3,100 cars across 45 classification tracks — much of that traffic feeds through this interlocking. Amtrak's City of New Orleans also passes through once in each direction daily, providing a welcome passenger train sighting amid the freight action.

The junction sits in south downtown Memphis, a low-lying area near the Mississippi River floodplain at roughly 280 feet elevation. The surrounding neighborhood is a mix of early 20th-century brick warehouses, newer loft conversions in the adjacent South Main Arts District, and patches of open ground along the right-of-way. The urban-industrial character dominates: overhead wires, crossing signals, and steel rails set against aging brick and concrete create a gritty aesthetic that lends itself well to documentary-style railroad photography.

To the west, the Hernando de Soto Bridge (I-40) arches across the Mississippi with its distinctive M-shaped illuminated structure, visible from parts of the junction area. The Harahan Bridge — a 1916 cantilevered through-truss railroad bridge now also carrying the Big River Crossing pedestrian path — sits just downstream. Nearby, the 1892 Frisco Bridge stands as the first span ever built across the lower Mississippi south of the Ohio River. This trio of bridges provides dramatic backdrop options for wider compositions. Humidity is a constant in Memphis, and summer heat shimmer can affect telephoto shots, but overcast days produce even, shadow-free light across the flat terrain.

Five Class I railroads operate in the Memphis gateway, making it one of the densest freight rail hubs in the southeastern United States. At Kentucky Street specifically:

Canadian National (ex-Illinois Central) runs the north–south Memphis Subdivision connecting Chicago, Memphis, Jackson (MS), and New Orleans. CN's nearby Harrison Yard — the railroad's second-largest facility in the U.S. at 433 acres — was rebuilt in a $100 million renovation and handles 35+ trains daily. Traffic is heavily intermodal and manifest, with unit grain, petroleum products, and mixed freight.

BNSF Railway operates the Thayer Subdivision (ex-Frisco) through Memphis, connecting to its network via the Harahan Bridge crossing into Arkansas. BNSF maintains Yale Yard in Memphis.

Union Pacific runs the Memphis Subdivision (ex-Missouri Pacific), also routing west across the Mississippi. UP operates Sargent Yard in Memphis and owns the Harahan Bridge.

CSX Transportation operates the Memphis Terminal Subdivision (ex-Louisville & Nashville corridor). CSX maintains Leewood Yard in the Memphis area.

Norfolk Southern maintains Forrest Yard in Memphis and interchanges traffic with the other carriers.

Amtrak's City of New Orleans runs one daily round trip on the CN main line between Chicago and New Orleans, stopping at Memphis Central Station, about 0.5 miles from the junction.

The dead-end of Kentucky Street places you at track level with unobstructed views of the diamond crossing. This is a ground-level vantage — there is no overpass or elevated platform — but the open terrain and converging sight lines compensate well.

Morning (east light): Southbound CN trains are nose-lit with clean eastern light. Westbound CSX and BNSF movements will be backlit, creating silhouette opportunities against the morning sky. A 70-200mm zoom captures individual locomotives well from the Kentucky Street position.

Afternoon (west light): Northbound CN trains catch golden side-light, especially attractive in the 2-3 hours before sunset. The western sky behind the Mississippi River bridges can produce vivid sunset backdrops for wide-angle compositions (24-35mm range).

Wide compositions: From positions south of the immediate junction area, the Hernando de Soto Bridge's illuminated M-shape and the Harahan Bridge truss structure can be framed with passing trains. These wider shots work best with a standard zoom (24-70mm).

Night photography: The area has some ambient light from nearby industrial facilities and street lighting. Long exposures can capture light trails from passing trains against the bridge lighting. The Mighty Lights LED installation on the Hernando de Soto and Harahan bridges adds color to nighttime compositions.

Memphis has been a critical railroad junction since the mid-19th century. The Illinois Central Railroad — CN's predecessor — built its main line south through Memphis connecting Chicago to New Orleans, establishing the city as a vital north–south rail corridor. The Louisville & Nashville Railroad (now CSX) pushed westward to secure a Mississippi River connection, while the St. Louis–San Francisco Railway (Frisco, now BNSF) and the Missouri Pacific (now UP) built east from Arkansas across the river.

The Kentucky Street interlocking evolved as these lines converged near the Mississippi River crossings. The area was historically controlled by an interlocking tower that managed the diamond crossing with manual levers before CTC (Centralized Traffic Control) automation took over.

Two landmark railroad bridges sit just west of the junction. The Frisco Bridge, completed in 1892, was the first bridge to span the Mississippi River south of the Ohio River — an engineering milestone that opened Memphis as a transcontinental rail gateway. The Harahan Bridge, completed in 1916 and named for Illinois Central president James Theodore Harahan (killed in a railroad accident during its construction), added two more rail tracks across the river. In 2016, one of the Harahan's abandoned roadway decks was converted into the Big River Crossing, now the longest pedestrian/cyclist bridge over the Mississippi at nearly one mile.

Memphis Central Station, opened in 1914 just half a mile south of the junction, served the Illinois Central and its subsidiary Yazoo & Mississippi Valley Railroad. After decades of decline following Amtrak's 1971 takeover of passenger service, the station underwent a $55 million renovation in 2019 and now houses the Central Station Hotel (Curio Collection by Hilton) alongside the active Amtrak stop.

Kentucky Street's defining feature is the at-grade diamond crossing shared by four Class I railroads — a configuration that is increasingly rare in modern American railroading. Memphis's distinction as one of only four U.S. cities served by five Class I carriers (CN, BNSF, UP, CSX, NS) means the variety of motive power and rolling stock passing through is exceptional. In a single session, you might see CN's distinctive orange-and-black GE Tier 4 units, BNSF's orange wedge scheme, UP's Armour yellow, CSX's dark blue, and Norfolk Southern's black thoroughbred livery.

The proximity to the Mississippi River crossings adds a dimension most inland junctions lack. Trains funneling toward the Harahan Bridge must converge through this area, concentrating traffic from multiple corridors into a narrow window. The contrast between modern high-horsepower locomotives and the century-old Frisco and Harahan bridge structures creates a visual timeline of American railroading. Add in the revitalized South Main Arts District and the historic Central Station just a short walk away, and this becomes one of the few urban railfan spots where you can combine serious train-watching with dining, museums, and walkable city amenities.
