Locomotive Inspection Act Claims: Strict Liability for Defective Locomotives
Last updated 21 June 2026
The Locomotive Inspection Act (LIA) — formerly the Boiler Inspection Act, now codified at 49 U.S.C. §20701 — is one of the most powerful tools in railroad-injury law. When a defective locomotive part contributes to an injury, the railroad is liable without the worker having to prove ordinary negligence, and the worker’s own contributory fault is disregarded.

The statute: Under 49 U.S.C. §20701, a railroad may use a locomotive only when its parts and appurtenances are “in proper condition and safe to operate without unnecessary danger of personal injury.” A violation, paired with FELA, creates liability without proof of negligence.
How the LIA supercharges a FELA claim
A FELA claim normally requires proving negligence. But the Supreme Court has long held that a violation of the Locomotive Inspection Act is negligence per se under FELA. If a defective locomotive part contributed to the injury, you do not prove the railroad was careless — the violation itself establishes liability.
The two big advantages
- No need to prove negligence. The defect is enough; the railroad’s duty under the LIA is treated as absolute.
- No contributory-fault reduction. Under 45 U.S.C. §53, when the injury results from a safety-statute violation, the worker’s own contributory negligence is not counted against the recovery at all.
Examples of LIA defects
- Defective or inoperative brakes
- Broken or missing handrails, grab irons, steps, and walkways on the locomotive
- Slippery or oil-covered locomotive surfaces
- Defective seats, controls, or cab equipment
- Excessive cab noise or vibration from unsafe components
- Inoperative or defective safety devices
LIA vs. the Safety Appliance Act
The LIA covers the locomotive and its parts. The closely-related Safety Appliance Act (49 U.S.C. §20301 et seq.) covers railcar appliances — couplers, automatic brakes, grab irons, ladders. Both work the same way through FELA: a proven violation is negligence per se and removes the contributory-fault reduction.
| Ordinary FELA claim | LIA-based claim | |
|---|---|---|
| Prove railroad negligence? | Yes (low bar) | No — defect is enough |
| Contributory fault reduces award? | Yes (§53) | No — disregarded |
| Key question | Was the railroad careless? | Was the part safe to operate? |
Proving an LIA violation
The case turns on the locomotive’s condition: inspection and repair records, FRA locomotive-inspection findings, the defect itself, and testimony. See proving railroad negligence for the evidence that documents a defective part.
