Headlines our live monitor matched as rail accidents. These are news reports, not FRA records: details may change and some will never meet the FRA reporting threshold.
Wisconsin train derailments by year
2026 covers January-August only. Each derailment is counted once, even when more than one railroad filed a report.
* 2026 to date (January-August, preliminary). Source: FRA Form 54, distinct accidents with accident type "derailment".
Top causes of train derailments in Wisconsin
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) · 7 derailments
2025 · 7 derailments
| Sub-group (2025-2026) | Derailments |
|---|---|
| Broken rails, joint bars, ties and fasteners | 3 |
| Track geometry: wide gauge, misaligned or buckled track | 3 |
| Vandalism, outside interference, under investigation or unknown | 2 |
| Switching moves: shoving, coupling, derails left on | 2 |
| Switches lined wrong, not locked or run through | 2 |
| Switches, frogs and other track appliances | 1 |
| Weather and debris: snow, ice, flood, tornado, high wind | 1 |
| Most common exact causes (FRA wording) | Derailments |
|---|---|
| Wide gage (due to defective or missing crossties) | 3 |
| Switch improperly lined | 2 |
| Interference (other than vandalism) with railroad operations by nonrailroad employee | 1 |
| Broken Rail - Base | 1 |
| Turnout frog (rigid) worn, or broken | 1 |

| Snow, ice, mud, gravel, coal, sand, etc. on track | 1 |
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.
Railroads with the most derailments in Wisconsin
By the railroad that filed the main report. Large railroads run far more train-miles, so a higher count does not by itself mean a worse safety record.
| Railroad | 2026 (to Aug) | 2025 |
|---|---|---|
| Escanaba & Lake Superior Railroad Company | 2 | - |
| Canadian National Railway | 1 | 2 |
| Canadian Pacific Kansas City | 1 | 1 |
| Wisconsin & Southern Railroad, Llc | 1 | 1 |

| Milwaukee | 1 |
| Adams | 1 |
| Douglas | 1 |
| Jackson | 1 |

Collisions and other train accidents in Wisconsin
Derailments are the largest group of rail equipment accidents. The same FRA reports also cover collisions, fires and trains hitting obstructions.
| Accident type (FRA) | 2026 (to Aug) | 2025 |
|---|---|---|
| Derailment | 7 | 7 |
| Highway-rail crossing collision | 1 | 4 |
| Hit an obstruction | 1 | 0 |
| Fire or violent rupture | 1 | 1 |
| Other impact | 1 | 0 |
| Other (see narrative) | 1 | 1 |
| All rail equipment accidents | 12 | 13 |
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.

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.
