A screening estimate for a private rail spur: track by the foot for your site conditions, turnouts, crossings, and the soft costs that surprise people — plus how long the drayage you stop paying takes to cover it.
Track at $200–$380 per foot for some grading or drainage work, turnouts at $35k–$120k each, crossings at $30k–$180k each, plus 10–25% for permits, environmental review, utility coordination and contingency. Excludes land and right-of-way entirely.

A screening number for deciding whether to commission a real estimate — not a budget. Site conditions, the sidetrack agreement, and permitting dominate, and approvals usually take longer than construction.
Search for what rail track costs and you will find figures from $4.55 to $250 per linear foot. They are not contradicting each other; they are pricing different things. The low numbers are rail, ties and ballast sitting in place on ground that was already flat. The high numbers are an engineered project with turnouts, grading, drainage, crossing protection and a permit stack.
This estimator deliberately anchors near the high end, because the low end describes a situation almost nobody building an industrial spur is actually in. If your ground is genuinely flat, dry and drained, pick that and the range drops accordingly.
Nothing here is a budget, and no parametric calculator can be. A spur on flat dry ground beside a quiet branch line and a spur threading wetlands to reach a busy signaled main are different projects that happen to share a length. Order-of-magnitude estimates built from generic per-mile figures have ended projects mid-construction.
Use this to decide whether the idea is worth an engineering estimate. Then get one, site-specific, before committing anything. Three things this model excludes entirely: land and right-of-way, the serving railroad’s sidetrack agreement terms, and the ongoing FRA inspection obligation the track carries once it exists.
The payback figure above counts only drayage — what you stop paying to truck between your plant and someone else’s railhead. That is the honest comparison, because the alternative to building a spur is usually not “stay all-truck.” It is using a transload facility that already exists.
An open-access transloader gets you rail line-haul economics with no capital project, no permitting, and no Part 213 obligation, in exchange for a handling fee and a short dray. For seasonal or modest volume that is frequently the better answer. Check what already exists near you before you spend money finding out what a spur would cost.
A greenfield private spur commonly runs $1.5 to $5 million all in, covering track, turnouts, grading, crossings, signals, permits and the railroad's sidetrack agreement. Smaller scopes are far less: a short spur on flat dry ground with one turnout and no signaling can come in near $250,000. The spread is enormous because site conditions, not track length, drive the number.
Published figures range from about $20 per foot for bare track materials in place to $250 and beyond for a fully engineered spur with turnouts and site work. The wide spread is mostly a question of what is included. A real municipal engineering estimate in Colfax, Wisconsin came in at $250 per foot, which is a more defensible planning number than any generic per-mile index because someone had to build to it.
Soil, grade and drainage first; then whether you need signaling or crossing protection. After that come the costs that do not look like construction: Section 404 wetland permits, NPDES stormwater, cultural resources review, local zoning and grading permits, NEPA review if there is any federal nexus, and utility coordination. Temporary traffic control, drainage work and contaminated soil remediation commonly add 5 to 20 percent.
Budget schedule, not just dollars. Approvals generally take longer than construction, and the serving railroad's sidetrack agreement is its own negotiation. Treat any estimate that talks only about cost as half an answer.
Once it is in service the track falls under FRA track safety standards in 49 CFR Part 213, with most industrial spurs classified as excepted track or Class 1 at 10 mph or less. That still means regular inspection and recordkeeping. Annual upkeep runs from a few thousand dollars for a short spur to six figures for a busy yard, and the sidetrack agreement decides whether you or the railroad carries it.
Often not, and that is the comparison worth running first. A spur trades a large capital project and an ongoing maintenance obligation for the drayage and handling you pay at somebody else's terminal. If your volume is modest or seasonal, an open-access transloader gets you rail economics with no capital and no FRA obligation. Check what already exists within dray range before you commission an engineering estimate.
Over a thousand transload facilities across 48 states, filterable by railroad and commodity — find one in dray range of your plant before you build.
