Marengo Lost Its Train in 1950. Now It Has a Chance to Get One Back.

After Huntley withdrew as a candidate stop on the planned Chicago-to-Rockford intercity passenger rail line, Marengo entered the conversation as a replacement. The proposal was presented to the city council on November 10, 2025, according to the meeting minutes. ¹ For a town of 7,700 that has had no passenger rail service since 1950, the offer is straightforward: a train to Chicago, on tracks that already run through town, paid for with state money.

The service would connect Chicago and Rockford with two round trips per day, funded by $275 million from Governor Pritzker's Rebuild Illinois capital program and operated under IDOT's authority. ² It would use existing Union Pacific tracks on the Belvidere Subdivision, which passes through the southern edge of downtown Marengo. IDOT's project timeline calls for construction in 2026 to 2027, with service potentially starting in 2027. This is not commuter rail. Two daily round trips would not replace a car for daily commuting. But for a community where the nearest Metra station is 25 miles away in Elgin, any direct link to Chicago is a significant shift.

The offer arrives at a particular moment for Marengo. The city has spent the last several years building the infrastructure to support growth. The $33.4 million I-90/Route 23 interchange opened in December 2019, giving Marengo its first direct highway connection to the Chicago suburbs. ⁶ A $8.46 million water and sewer extension along Route 23 is under construction, with two more phases planned. ⁷ A 37-acre commercial development by DK & KT Holdings is in the pipeline near the interchange. ⁸ The comprehensive plan adopted in 2024, the city's first update in 20 years, explicitly identified a potential rail connection as a long-term goal. ⁴

The fiscal backdrop matters. Marengo's general fund budget for 2026 to 2027 is $6.49 million, balanced but tight. ⁹ Property taxes are rising nearly 5%. The city's online use tax revenue collapsed from $280,000 to a projected $20,000 after a state law change. ⁹ The non-home rule municipal sales tax, approved by voters, generates $700,000 to $800,000 a year. ¹⁰ Every infrastructure decision gets weighed against a budget with little margin. A rail stop that costs the city nothing is appealing. A rail stop that creates new costs is a harder sell.

Willing to continue conversations as long as there is no financial cost to the city.

Marengo's relationship with rail is older than most of the buildings on State Street. The Galena and Chicago Union Railroad, the first railroad built west from Chicago, reached Marengo in 1851. Passenger service ran for nearly a century under the Chicago and North Western Railway before ending around 1950. The town's original depot survives: the Illinois Railway Museum in nearby Union rescued it in 1967, and it remains the oldest railway station in regular passenger use west of Pittsburgh. ³ Marengo also had an interurban trolley, the Elgin and Belvidere Electric Company, which operated from 1907 until automobile competition ended it in 1930.

When rail service ended, Marengo became entirely car-dependent. The average one-way commute in McHenry County is 34 minutes by car. ⁵ There is no transit alternative. Residents who work in the Chicago suburbs, as many do, drive to Schaumburg or Arlington Heights on routes that have not kept pace with growth. The I-90 interchange improved highway access, but it did not solve the underlying problem: Marengo has no connection to the regional transit network.

The broader growth dynamics in McHenry County make the rail question more than theoretical. The eastern half of the county, closer to the Chicago suburbs, is booming: Huntley is adding nearly a thousand residents a year. ¹¹ The western half, where Marengo sits, has grown more slowly. Marengo's population is up 2.9% since 2020, a fraction of the pace in towns 15 miles to the east. The pattern mirrors earlier waves of suburban expansion. What reaches the I-90 corridor eventually pushes west.

A rail stop would not cause that growth, but it could shape it. The comprehensive plan envisions a walkable downtown with mixed-use development, not more strip commercial along the highway. ⁴ A passenger rail connection supports that vision by making the downtown core, not the interchange, the point of access to the wider region. That is the long-term argument. The short-term argument is simpler: a state-funded rail stop brings jobs, construction spending, and visibility to a town that is trying to attract both residents and businesses.

The proposed stop would require a 350-foot passenger platform at Taylor Street. According to the council minutes, that means permanently closing Taylor Street to vehicle traffic and converting the adjacent municipal parking lot for station use. ¹ Those are tangible costs. Taylor Street connects to the downtown core, and the parking lot serves State Street businesses. Displacing that parking without a replacement plan would create friction with the merchants the city is trying to support.

Several questions remain unanswered. Who funds and maintains the platform? How would displaced parking be replaced? What happens to Taylor Street traffic? Huntley cited traffic and location concerns when it withdrew, according to the council minutes. ¹ Marengo would need to evaluate similar trade-offs, ideally through a public process that weighs the real costs against the long-term value of regional connectivity.

The council's position, as recorded in the November minutes, was cautious but open: willing to continue conversations as long as there is no direct financial cost to the city. ¹ Alderman Weiss called for a public meeting if the proposal advances. Residents who spoke were split. Supporters cited economic potential. Opponents raised traffic and parking concerns.

No vote has been taken and no formal proposal is before the council. The next step would be a public meeting to present specifics. As of March 2026, no such meeting has been scheduled. The tracks are already there, running through town the way they have since 1851. The question is whether Marengo will use them again.
