Nearly two decades after initiating efforts to construct an underpass beneath Canadian National’s (CN) railroad tracks on U.S. Route 14 in Barrington, Illinois, Karen Darch, former village president and longtime community advocate, is facing a renewed challenge as railroad mergers threaten to increase freight traffic through the Chicago suburbs. The $94 million underpass project, anticipated to be completed by the end of next year, aims to alleviate congestion and improve safety, but recent developments raise concerns about its sufficiency in managing future rail volumes.

Union Pacific’s proposed $85 billion acquisition of Norfolk Southern includes plans to increase freight train operations over CN’s suburban Chicago network, which currently serves as a bypass route around inner-city Chicago. This rerouting is expected to shift some freight traffic away from congested urban lines, but it also carries the potential for intensified rail activity through communities like Barrington, located roughly 35 miles northwest of Chicago.

Darch anticipates that, given CN’s ongoing efforts to double-track rail lines approaching Barrington, a second freight track may be constructed through the village, increasing daily train traffic possibly from 20 to dozens of freight trains running at speeds up to 40 miles per hour. This escalation would add to existing transportation pressures, including approximately 50,000 vehicles and trucks, 800 daily school bus trips, and 70 Metra commuter trains traversing Barrington’s downtown area each day. She stresses the need for additional infrastructure, such as more underpasses, and advocates for greater financial contributions from businesses benefiting from rail transportation.

Meanwhile, the broader railroad industry is grappling with uncertainties stemming from consolidation moves. Peter Gilbertson, chief executive of Anacostia Rail Holdings Co., which operates six short line railroads in major U.S. cities including Chicago and Los Angeles, expressed concerns about the impact of Union Pacific’s proposed merger. He noted that while a unified rail system could offer some service and cost advantages, the focus on restructuring may detract from efforts to enhance service quality. Gilbertson’s operations, notably the South Shore & South Bend Railroad crucial for hauling steel and other commodities, could face competitive challenges if Union Pacific is able to leverage increased pricing power post-merger.

Regulatory scrutiny of the merger remains intense. On August 18, the Surface Transportation Board (STB) denied Union Pacific’s request to withhold key modeling data related to traffic and market share, extending the timeline for a thorough competitive review that could last an additional year. Critics, including seven state attorneys general and major shippers, argue that Union Pacific has not sufficiently demonstrated that the merger would improve competition as required by STB guidelines.

Union Pacific contends that the transaction will create America’s first transcontinental railroad, offering faster, more reliable, and cost-effective coast-to-coast freight service that can reclaim market share from long-haul trucking. CEO Jim Vena underlines the urgency to grow rail volumes amid two decades of stagnant industry growth. However, independent analysts warn that consolidation could reduce competition and limit innovation, potentially harming both the industry and the communities affected by increased freight traffic.

The stakes extend beyond Barrington. Gilbertson’s company recently lost a key contract operating dockside rail services at the ports of Los Angeles and Long Beach, North America’s busiest port complex, to a joint venture between Union Pacific and BNSF Railway. The transition marks a shift in control over critical port rail operations and underscores the increasing influence of Class 1 railroads in strategic freight corridors.

Historically, the rail corridor through Barrington—part of the Elgin, Joliet & Eastern Railway acquired by U.S. Steel in 1901—has served as a vital freight and commuter passage. CN’s acquisition of the EJ&E in 2007 led to a notable surge in train traffic, intensifying safety and congestion concerns. Despite extensive community advocacy culminating in federal and state support for the current underpass project, residents like Darch remain wary about the implications of further rail traffic growth without corresponding infrastructure investments.

As the North American railroad landscape undergoes significant transformation through mergers and operational realignments, suburban communities along key freight routes face ongoing challenges balancing economic benefits with quality of life and public safety considerations.
