Windsor (Ontario)

The College Avenue overpass is the most accessible vantage point on the Canadian side, placing you directly above the CPKC approach as trains accelerate away from the tunnel portal or slow for the descent under the Detroit River. From the overpass railing you can observe the full consist as it threads below — typically 80–120 cars of intermodal stacks, automotive multi-levels, or mixed manifest freight — with an unobstructed sight line in both directions along the approach. The Essex Terminal Railway's elevated mainline also crosses directly over the CPKC approach tracks, offering a rare top-down angle on locomotive rooflines and consist details.

Train speeds near the portal are modest (roughly 30–50 km/h as crews transition between surface and sub-river operation), making panning shots manageable and giving ample time to read reporting marks as the consist rolls past. For advance notice of incoming moves, tune a handheld scanner to CPKC road frequencies — consult RadioReference.com for current CPKC Ontario (Windsor Subdivision) channels. The portal area is open to the sky on the Canadian approach, so there are no overhead obstructions to complicate photography. Evening and overnight trains are equally visible thanks to adequate street lighting along Wyandotte Street West.

The tunnel approach occupies a narrow right-of-way squeezed between Wyandotte Street West and the Detroit River shoreline, in a neighbourhood of low-rise residential streets and auto-related businesses. The setting is entirely flat and at river level, giving unobstructed sight lines from the College Avenue overpass in both directions along the CPKC tracks. Riverside Drive West, just to the south, opens up expansive waterfront views: on clear days the towers of the Renaissance Center and the span of the Ambassador Bridge frame the scene across the river.

Windsor sits at roughly the same latitude as northern California, giving it one of the most temperate climates in Ontario, though summers are genuinely hot and humid — consistently among the most humid cities in Canada. The Detroit River channels strong northwest winds between October and March; a wind layer is advisable for winter sessions. The area is well-lit at night, making dawn and dusk visits practical. Autumn brings pleasant riverside conditions and cooler, drier air that keeps locomotive exhaust visible in dramatic plumes.

CPKC (Canadian Pacific Kansas City) is the exclusive regular operator of the Michigan Central Railway Tunnel, routing its Windsor Subdivision freight between London, Ontario and Detroit, Michigan through this crossing. Train types include intermodal double-stack containers (a staple since the north bore's $27-million enlargement in 1993 that raised the clearance envelope), automotive multi-level racks serving the Windsor–Detroit automotive manufacturing corridor, unit manifest freights, and occasional high-and-wide dimensional loads. Based on historical throughput data of approximately 900,000 rail cars annually through the tunnel, a realistic daily estimate is 15–25 CPKC trains — distributed fairly evenly around the clock, since freight railways operate on industrial demand rather than commuter schedules.

Canadian National Railway uses the Windsor tunnel only as an emergency detour when incidents block their primary crossing at the Sarnia Tunnel (St. Clair River, ~60 km north); on those rare occasions CN power and consists appear alongside regular CPKC traffic. The Essex Terminal Railway (ETL), Windsor's historic shortline founded in 1902 and operating 54 km of track in the Windsor–LaSalle–Amherstburg corridor, also provides locomotive-spotting opportunities in the surrounding industrial area. Amtrak and VIA Rail have publicly explored restoring passenger service through the tunnel — an extension of the Chicago–Detroit corridor into Windsor was under discussion as of 2025, though no date has been confirmed.

The College Avenue overpass is the primary framing position, offering a slightly elevated angle looking south toward the portal. A moderate telephoto lens (100–200mm on full-frame) fills the frame with the lead locomotive and first several cars while keeping the industrial roofline and distant Windsor skyline in context. Morning light (8–11 AM) from the northeast illuminates the engineer's side of westbound consists leaving the tunnel; late-afternoon photographers switch to the west side of the overpass for golden-hour light on eastbound trains entering the tunnel.

The Essex Terminal elevated structure provides a strikingly different perspective — almost straight down onto locomotive rooftops — rarely achievable from ground level and useful for consist and detail shots. For wide establishing compositions that include the Ambassador Bridge or the Detroit skyline, Riverside Drive West between McDougall and Cameron avenues provides a clean background composition; a long telephoto (200–400mm) from Riverside compresses the river crossing backdrop against approaching trains on the elevated approach. Night photography is feasible given adequate street lighting, and winter cold air produces dramatic exhaust plumes from idling or working locomotives.

The Michigan Central Railway Tunnel opened for passenger service on July 26, 1910, replacing the train car ferry service that had crossed the Detroit River since 1877. Freight service through the twin bores commenced on September 15, 1910. The tunnel was built using the immersed tube method — steel tube sections fabricated on land, floated into position, and sunk into a trench in the riverbed — making it the first immersed-tube tunnel in the world to carry rail traffic. Construction cost over $8 million and was engineered under the supervision of William J. Wilgus, vice president of the New York Central Railway. The Detroit River Tunnel Company, a joint Canadian-American entity, was incorporated in 1905 to manage the international crossing.

Michigan Central operated the tunnel for decades before its eventual acquisition by Canadian Pacific. In 1993, CP Rail invested $27 million to enlarge the north bore to allow passage of double-stack intermodal containers and full-height automobile carriers that had previously required ferrying or alternative routing. Windsor's automotive industry — built around Ford of Canada and Chrysler (now Stellantis) assembly operations — has depended on this tunnel for over a century of parts delivery and finished-vehicle shipments. The tunnel predates the Ambassador Bridge (1929) and the vehicular Detroit–Windsor Tunnel (1930), making it the oldest operating international crossing between Canada and the United States in the Windsor–Detroit corridor.

The Windsor tunnel portal is one of very few locations in Canada where railfans can legally observe active freight trains entering and exiting an international railway tunnel — and one of an even smaller number where the viewing is free, easy, and within walking distance of downtown amenities. The CPKC Windsor Subdivision's role as a primary automotive-freight corridor gives the spot a distinctive cargo personality: automotive multi-level racks loaded with vehicles from Windsor's Stellantis and Ford assembly plants make up a significant share of consists, providing a direct visual connection between the rail corridor and regional industry. The combination of the 115-year-old tunnel, the Essex Terminal Railway's heritage shortline activity in the surrounding area, and the framing of trains against the Detroit skyline and Ambassador Bridge creates a layered narrative that few other single-location shots can match. Unlike wide-open prairie or mountain locations, the tunnel approach acts as a bottleneck — all CPKC Windsor traffic funnels through a single point, guaranteeing regular action without extended waits.
