MPO briefs officials on Crandick corridor reuse: rail, bus rapid transit or 'pop up metro' under consideration

Kevin Ralston, executive director of the local Metropolitan Planning Organization (MPO), presented options to regional officials at a January 2025 joint entities meeting for reusing the Crandick rail corridor between North Liberty and Iowa City.

Ralston said planning‑level work over the last decade produced multiple studies — a 2015 passenger‑rail conceptual study, a 2016 Iowa City–North Liberty focused phase, a 2018 rails‑to‑trails review, a 2020 commuter rail study and a recent bus‑rapid‑transit (BRT) feasibility analysis. He summarized three current options: a diesel multiple‑unit passenger rail, bus rapid transit using electric buses, and a leased pilot known as the pop up metro light‑rail demonstration.

"The corridor I'd like to talk about today is really this 9 mile stretch," Ralston said, describing the alignment from Penn Street in North Liberty to Burlington Street in Iowa City. He said the passenger‑rail concept envisioned seven stations, about a 25‑minute end‑to‑end run, roughly 5,300 daily rides Monday–Friday and a capital cost originally estimated at about $60 million (inflated to current dollars in the studies). Annual operating cost in that study was about $5.9 million. "The capital cost for that service was about $60,000,000," he said.

The BRT option was modeled as running from Clinton Street in Iowa City to Penn Street in North Liberty with as many as 18 stops, a roughly 27‑minute end‑to‑end run, 15‑minute peak frequency, about 4,300 weekday rides in estimates and a capital cost the MPO estimated at about $87.4 million with an annual operating cost the presentation listed at about $50.4 million. Ralston said the BRT study included weekend service to match Federal Transit Administration (FTA) grant requirements.

The pop up metro proposal would lease two battery‑electric train sets for a roughly three‑year demonstration. Ralston gave a capital cost estimate for the leased demonstration of about $5.7 million and an annual operating figure of about $3.7 million for those years. He said the demonstration’s purpose is to test actual ridership with real vehicles rather than relying solely on modeling.

Ralston outlined tradeoffs: trains may attract more riders, BRT is more adaptable to demand and existing local transit agencies are more familiar with bus operations. He warned that converting the corridor to BRT would likely require track removal and would trigger regulatory review by the federal Surface Transportation Board. "Bus rapid transit requires removal of the tracks, and some potential for regulatory snags," he said.

Panel members and officials asked about ownership and lease terms. Ralston said the railroad has indicated willingness to discuss offloading service and that discussions about sale or long‑term lease were still to be determined. "They have said that what's best for the community is best for the Grand River Road," he said, while noting specific commercial service frequencies vary and some freight activity remains seasonal.

On formal policy, Ralston told the group that Johnson County had passed a non‑binding resolution expressing a preference for the pop up metro pilot and inviting peer municipalities, the University of Iowa and UIHC to provide responses by February. He characterized the county resolution as non‑binding and subject to further fact‑finding and cost considerations. "Last month, the county did pass a non binding resolution just expressing that given what we know at this time, it is our preference to move ahead with pop up Metro," he said.

Ralston closed by listing next steps: select a preferred mode (rail or bus), coordinate timing with the railroad on abandonment or lease issues, identify an operating agency, secure operating‑cost funding (noting infrastructure grants commonly cover capital more readily than ongoing operations) and prepare grant applications to advance design and construction.

During the discussion, a councilmember asked whether the studies’ ridership estimates were based on surveys or modeling; Ralston said both methods were used, including a dedicated ridership survey intended to support federal grant applications. A school district representative asked whether new operations would change student safety near schools; Ralston said both the passenger‑rail and BRT studies contemplated fencing and other safety measures but that precise impacts would need further analysis.

No final binding decision was made at the meeting; the county resolution is advisory and further intergovernmental coordination, funding decisions and regulatory approvals will be required before any mode is chosen or implemented.
