Joliet Union Station

Joliet Union Station sits at the intersection of seven railroads — BNSF, Union Pacific, Canadian National, CSX, Iowa Interstate, Metra, and Amtrak — making it one of the busiest and most diverse rail junctions in the Chicago metropolitan area. Trains Magazine has called Joliet one of the top trainspotting locations in the region.

The historic 1912 station no longer serves passengers; Amtrak and Metra moved to the adjacent Joliet Gateway Center in April 2018. However, the junction itself remains intensely active with 75-plus train movements every 24 hours. The primary viewing areas are the sidewalks around the Gateway Center and the preserved UD Tower, now home to the Joliet Railroad Museum (open Thursday through Sunday, 10 AM to 2:30 PM, $5 admission). The tower's third-story observation level gives a bird's-eye view of trains converging from four compass directions.

The original 1912 station platform is fenced off and restricted to clients of the banquet hall that now occupies Union Station. The Rock Island District platform east of the crossing is accessible and offers views of north-south freight traffic. The Amtrak platform is signed for ticketed passengers only. Both platforms connect via stairs and elevators from the Gateway Center. A car is recommended for reaching other Joliet rail viewing spots, though Metra Rock Island District trains from Chicago's LaSalle Street Station terminate here.

The junction sits in downtown Joliet along the west bank of the Des Plaines River at roughly 580 feet elevation. The terrain is flat urban landscape, with the raised railroad embankment — a product of the 1909-1912 track elevation project — dominating the surroundings. The restored Bedford limestone facade of the 1912 Union Station, with its arched Palladian windows and classical ornamentation, provides a distinguished architectural backdrop for train photography.

Nearby landmarks include the Will County Courthouse, Duly Health and Care Field (home of the Joliet Slammers minor league baseball), and the 1926 Rialto Square Theatre two blocks north. The Des Plaines River and its lock system are within a short walk east. Joliet's downtown has been undergoing revitalization since the Gateway Center's $51 million construction, and the area is generally safe for daytime visits, though visitors should exercise normal urban awareness.

Weather follows typical northeastern Illinois patterns: hot, humid summers with long daylight hours; bitterly cold winters with lake-effect snow squalls from Lake Michigan; and pleasant spring/fall seasons ideal for trackside visits. Low-angle winter light illuminates the north-south tracks dramatically in the golden hours.

The junction sees roughly 75 or more train movements per 24 hours across multiple operators and subdivisions:

BNSF Railway operates on the former Santa Fe Chillicothe Subdivision with 50-plus trains daily, predominantly double-stack intermodal. The two BNSF main tracks are closest to the historic Union Station on the west side of the crossing.

Union Pacific / Canadian National share the other north-south pair of tracks (the former Chicago & Alton / Gulf, Mobile & Ohio main line to Springfield and St. Louis). UP traffic is increasing with the Global IV intermodal facility about 5 miles south on the Joliet Subdivision. CN traffic on this line is mostly local. Coal trains also use the Joliet Sub heading to and from the ComEd power plant south of Joliet.

Metra is the dominant passenger operator. The Rock Island District runs 23 trains each way on weekdays, 10 each way Saturdays, and 8 each way Sundays/holidays between Joliet and Chicago's LaSalle Street Station. The Heritage Corridor operates 3 trains each way on weekdays only, running via the CN/UP Joliet Sub to Chicago Union Station.

Amtrak runs 8 daily Lincoln Service trains on the Chicago-St. Louis corridor plus the daily Texas Eagle (Chicago-San Antonio), all on UP's line.

CSX and Iowa Interstate operate on the ex-Rock Island line west of the station. Traffic is limited — usually a CSX local each direction daily plus Iowa Interstate road freights and extras.

The UD Tower observation deck (third floor of the Joliet Railroad Museum) is the premier vantage point, offering an elevated 360-degree view of trains approaching from all four directions. Best for wide-angle overview shots and capturing meets at the diamond crossing. Admission is $5.

From the Rock Island District platform east of the crossing, you can get clean three-quarter shots of north-south BNSF and UP freights with the limestone Union Station facade as background. A 70-200mm zoom lens works well from this distance. Morning light (east-facing) illuminates westbound trains on the ex-Rock Island line; afternoon light favors the station's east-facing facade.

The Jefferson Street Overpass offers elevated views of the UP/CN tracks curving northward, with the Will County Courthouse dome visible in the background. The free parking lot south of the railroad bridge on Martin Luther King Drive (formerly Chicago Street, accessible via I-80 to IL Route 53) is a convenient staging point with good sight lines.

Night photographers will find dramatic opportunities with multiple signal aspects and headlight beams converging through the interlocking. Long exposures from the platform areas capture light trails effectively.

Rail service reached Joliet in 1852 with the Chicago and Rock Island Railroad. By 1885, four trunk lines served the city: the Rock Island; the Atchison, Topeka & Santa Fe; the Chicago & Alton; and the Michigan Central — each maintaining separate depots. Two belt lines, the Elgin, Joliet & Eastern and the Chicago, Milwaukee & Gary, also operated through the area. Over 60 trains per day passed through downtown by the late 19th century.

A major track elevation project began in 1909 to address traffic congestion and grade-crossing safety. The project raised the rail lines through downtown and included construction of a new union station at the intersection of the Rock Island and Alton main lines. Designed by architect Jarvis Hunt — who also designed Kansas City Union Station — and built by the Adam Groth Company, Joliet Union Station opened on October 14, 1912, at a cost of $250,000. The Beaux-Arts structure features a steel frame, Bedford limestone facade, bronze fixtures, and Tennessee marble interiors. At its peak, the station served over 100 intercity trains per day from its 8-track, 16-diamond junction.

The station declined through the mid-20th century. The Michigan Central discontinued service in 1925, the ground-floor ticket lobby closed in the late 1940s, and a dropped ceiling was installed in the grand waiting room in 1960. Listed on the National Register of Historic Places in 1978, the station was purchased by the city and Metra in 1987 and restored by 1991. Amtrak served the station until 2014, and Metra until the Gateway Center opened in April 2018. The circa-1913 interlocking tower (UD Tower) has been preserved as the Joliet Railroad Museum within the Gateway Center complex.

Joliet stands out as one of the few locations in the Midwest where seven different railroad operators — BNSF, Union Pacific, Canadian National, CSX, Iowa Interstate, Metra, and Amtrak — all converge within sight of a single vantage point. The perpendicular crossing of the north-south BNSF/UP main lines with the east-west ex-Rock Island route creates constant dispatching choreography visible from the UD Tower observation deck.

The combination of a preserved 1912 Beaux-Arts station, a working interlocking tower turned railroad museum, and the modern Gateway Center provides historical context rarely found at active rail junctions. The station was designed by Jarvis Hunt, the same architect behind Kansas City Union Station, making Joliet part of a notable lineage of early 20th-century rail architecture.

Scanner enthusiasts have abundant activity to monitor across multiple frequencies: BNSF 160.650, CN 160.920, UP 161.280, Metra 161.340, CSX 160.230/160.290, and Iowa Interstate 160.305. The interplay between freight dispatching on the BNSF Chillicothe Sub and passenger priority for Metra creates a dynamic listening experience.
