CSX Completes Avon Yard Hump Lead Extension

CSX Completes Avon Yard Hump Lead Extension, Bringing New Capacity Online in Indianapolis

Published: February 21, 2026

CSX says it has finished a key infrastructure upgrade at its Avon Yard in Indianapolis, completing the “cutover” of a newly extended hump lead that the railroad expects will improve yard fluidity, reduce railcar dwell time, and increase overall classification capacity through one of its most important Midwestern terminals. According to the large eastern Class 1, the project added 3,500 feet of new track, extending the yard’s hump lead to a total of 8,000 feet.

For readers less familiar with hump yards: a “hump” terminal classifies freight cars by pushing cuts of cars over a slight grade (the hump), then letting the cars roll—under controlled speeds—into specific classification tracks. The hump lead is the approach track where inbound cuts are assembled and staged before being shoved over the hump. In a busy terminal, lead length can be a hard physical constraint: if the lead is too short, longer trains must be “double-cut” (broken into two or more moves) before classification can even begin, creating extra switching moves, more time on the ground, and more congestion on the plant.

CSX’s stated goal with the extension is straightforward: handle full-length trains in a single cut, streamline remote-control switching operations, and reduce the time cars spend waiting inside the terminal. The railroad says the extended lead will allow Avon Yard to handle roughly 200 to 300 additional railcars per day.

In yard terms, that’s a meaningful step up: more daily cars classified generally translates to better terminal velocity, fewer bottlenecks for inbound/outbound trains, and improved schedule reliability for customers whose freight routes through Indianapolis and the surrounding CSX network. The railroad framed the project as producing “measurable gains in efficiency, capacity, and railcar velocity.

In its announcement, the railroad emphasized three operational benefits enabled by the longer lead:

Processing full-length trains in a single cut (reducing or eliminating double-handling)
Improving remote-control switching movements (more room to work can reduce stop-and-go choreography and conflicts)
Reducing railcar dwell time, improving the overall “fluidity” of freight moving through the terminal

CSX also included a quote from David Clark, director of construction engineering, who described the underlying objective as switching cars “as quickly as possible” so they don’t spend unnecessary time in the yard, adding that the extension gives yard teams “the room they need to operate more effectively and deliver better service.”

Trade coverage and CSX’s own communications point to a multi-month build:

The railroad had outlined the Avon Yard program in mid-2025, noting the hump lead would be extended from 6,400 feet to 8,000 feet, with completion expected by the end of the year.
Progressive Railroading reported that work began in May 2025, with tasks including ballast placement, moving new track into position, and tamping.
CSX’s completion announcement is dated January 28, 2026, describing a “successful cutover” of the extended lead—industry shorthand for placing the new track configuration into active service.

The railroad emphasized that the construction effort was completed incident- and injury-free, positioning the project as an example of its “do work the right way” approach and its broader safety culture. That point matters in a terminal environment where construction staging, heavy equipment movement, and ongoing yard operations often have to coexist—especially when upgrades are performed without shutting down the facility.

CSX has described Avon Yard as one of its five hump yards, and the company has tied the Indianapolis improvements to a broader push to enhance operational efficiency and customer service.

In the July 2025 release previewing the work, CSX quoted Avon Superintendent Jeff Exline saying the changes would reduce out-of-route miles, increase traffic volumes by up to 15%, and enable the terminal to process up to 300 more cars daily—a figure closely aligned with the capacity gain CSX is now citing post-completion.

While CSX’s announcement focuses on the engineering achievement, the practical implications for shippers tend to show up in a few predictable ways when a major yard constraint is removed:

Faster classification cycles: If inbound trains can be humped in a single move, cars can reach outbound blocks sooner—reducing dwell and improving trip-plan adherence.
Fewer yard conflicts: Longer working room can reduce the number of intermediate moves that occupy key leads and ladders, especially during peak arrival windows.
Better resilience: Extra daily capacity acts as a buffer when the network is stressed by weather, surges in volume, or irregular train arrivals.

CSX’s framing—capacity, velocity, dwell—signals it expects the hump lead extension to deliver benefits not only within Avon Yard, but also to improve network flow for freight moving across the Midwest corridors that funnel through Indianapolis.
