Why trains derail

Top causes of train derailments in Idaho

The railroad codes a primary cause on every report from FRA's train accident cause code list. We group the codes into FRA's five main groups and their sub-groups, in plain English.

2026 (to August) · 8 derailments

Track defects (rails, ties, switches, roadbed)
4 · 50%
Human factors (crew actions and rules)
3 · 38%
Equipment failures (cars and locomotives)
1 · 13%

2025 · 12 derailments

Track defects (rails, ties, switches, roadbed)
9 · 75%
Human factors (crew actions and rules)
2 · 17%
Equipment failures (cars and locomotives)
1 · 8%
Sub-group (2025-2026)Derailments
Track geometry: wide gauge, misaligned or buckled track6
Broken rails, joint bars, ties and fasteners4
Train handling and make-up (slack action, braking, heavy cars placed wrong)2
Roadbed: soft, settled or washed-out ground2
Switches, frogs and other track appliances1
Hand brakes and securing parked cars1
Couplers and draft gear1
Switching moves: shoving, coupling, derails left on1
Wheels (worn or broken)1
Switches lined wrong, not locked or run through1
Most common exact causes (FRA wording)Derailments
Wide gage (due to defective or missing crossties)3
Roadbed settled or soft2
Broken Rail - Base2
Other track geometry defects2
Worn rail1
Switch point worn or broken1
Failure to release hand brakes on car(s) (railroad employee)1
Coupler retainer pin/cross key missing1
Failure to couple1
Automatic brake, excessive1

Counts for 2025 and 2026 to date. The sub-groups sum only the top rows. A cause "under investigation" is updated when the railroad amends its report.

Collisions and other train accidents in Idaho

Derailments are the largest group of rail equipment accidents. The same FRA reports also cover collisions, fires and trains hitting obstructions.

Highway-rail crossing collision02
Hit an obstruction01
Other impact12

Highway-rail crossing crashes appear here only when train or track damage passed the FRA threshold; most crossing crashes are reported on a separate form (FRA F 6180.57) and are not in this table.

Questions

Train derailments: FAQ

How many train derailments have there been in Idaho in 2026?
FRA accident reports show 8 train derailments in Idaho from January to August 2026, against 9 in the same months of 2025. The most recent months can still grow as late reports arrive. Each derailment is counted once even when two railroads reported it.
Was there a train derailment today?
Official FRA data runs about 2-3 months behind (the latest record is from 31 August 2026). For derailments reported in the last 24 hours, see the accidents today page and the live map on our home page, which pull rail accident reports from news sources every 15 minutes.
What causes most train derailments?
In 2025-2026 FRA data for Idaho, the most common cause group is track defects (rails, ties, switches, roadbed) (65% of derailments with a coded cause). Track problems such as wide gauge from bad crossties and broken rails, and human factors such as switches lined wrong and shoving moves in yards, lead the list. 75% of the derailments mapped here happened at 10 mph or less, typically in yards and sidings.
Where can I see a map of train derailments in Idaho?
The map on this page shows every derailment in Idaho reported to the FRA for 2025 and 2026, coloured by severity: red when someone died or hazardous material was released, amber for injuries or damaged hazmat cars.
How many train derailments happen a year in the US?
Between 2015 and 2025, FRA data counts roughly 991 to 1,377 train derailments a year in the United States (991 in 2025). Only accidents above the FRA damage reporting threshold are counted.
Where does this data come from?
From the Federal Railroad Administration (FRA): railroads must file Form FRA F 6180.54 for every rail equipment accident above a damage threshold. The data is published on data.transportation.gov and is US government public domain.
Sources and method

About this data

  • Source: Federal Railroad Administration, Rail Equipment Accident/Incident Data (Form 54) on data.transportation.gov (readable view of the source dataset aqxq-n5hy). US government work, public domain. Cause groups: FRA train accident cause codes (Appendix C of the FRA reporting guide).
  • What is counted: accidents with FRA accident type 01 (derailment) that caused damage above the FRA reporting threshold. Each accident is counted once by its FRA incident key, even when two or three railroads filed reports. Killed and injured are the accident totals; hazmat cars are added up across the railroads' reports.
  • Lag: railroads report each month's accidents by the end of the following month and FRA publishes after that, so the data runs 2-3 months behind. The latest month can still rise as late reports arrive. This page re-checks FRA once a day.
  • Map positions are the latitude and longitude the railroad entered on the report; a few may be approximate.
  • Not included: accidents below the damage threshold, transit systems that do not report to FRA, and Canada. Canadian rail occurrence statistics are published by the Transportation Safety Board of Canada.
