After a train accident in Colorado, evidence is everything. The strength of your injury claim depends on what can be proven — and critical evidence in train cases has a short shelf life. Surveillance footage gets overwritten, physical hazards get repaired, and witness memories fade within days. Knowing what to collect and how to preserve it can make or break your case.
Whether you were a passenger on an RTD light rail train, standing on a platform, or near the tracks when an accident occurred in Denver or Aurora, the steps you take immediately after the incident determine how effectively your attorney can pursue your claim.
Key Takeaways
- Evidence in train accident cases degrades quickly — surveillance footage gets overwritten, physical conditions change, and witness memories fade within days.
- Critical evidence includes surveillance video, event data recorder (black box) data, maintenance logs, operator training records, and prior incident reports for the same location.
- Preserving evidence often requires sending a formal spoliation letter to the transit agency and railroad company demanding they retain all records related to the incident.
Why Evidence Collection Matters in Train Accident Cases
Train accident claims are fundamentally different from car accident claims. The entities involved — RTD, freight railroads, maintenance contractors — are large organizations with legal teams that begin building their defense immediately after an incident. They control access to most of the critical evidence: surveillance cameras, event data recorders, maintenance logs, and operator records.
If you do not act quickly to preserve this evidence, it may be altered or destroyed before your attorney can access it. This is not necessarily intentional — routine data overwrite policies and maintenance repairs happen on schedule regardless of pending claims.
Important
RTD and railroad companies are not required to preserve surveillance footage or maintenance records indefinitely. Security camera footage is often overwritten within 30 to 90 days. If your attorney does not send a formal preservation letter quickly, critical evidence of what caused the accident may be lost forever.
Types of Evidence in Train Accident Cases
A thorough train accident investigation draws on multiple evidence sources:
Physical Evidence
- Photos and videos of the accident scene, including track conditions, platform hazards, and weather
- Your clothing and personal belongings damaged in the incident
- Physical conditions of the track, switches, signals, and platform at the time of the accident
Electronic Evidence
- Event data recorders (EDR) — the train’s “black box” captures speed, braking, throttle position, and signal responses
- Surveillance footage — station cameras, onboard cameras, and nearby traffic or security cameras
- Signal system data — records showing whether signals were functioning correctly
- GPS and dispatch records — showing train locations and communications at the time
Documentary Evidence
- Maintenance and inspection logs for the train, tracks, and signals
- Operator training and certification records
- Prior incident reports at the same location or involving the same equipment
- FRA (Federal Railroad Administration) compliance records
- Weather reports for the date and time of the accident
Witness Evidence
- Statements from other passengers, bystanders, and station staff
- Contact information for anyone who saw the accident or the conditions that caused it
Steps to Preserve Evidence After a Train Accident
Time is critical. Take these steps as soon as possible after a train accident:
- Call 911 and get medical attention. Even if injuries seem minor, a medical record starting from the date of the accident establishes the connection between the incident and your injuries.
- Document everything at the scene. Take photos and videos of the tracks, platform, your injuries, weather conditions, and anything that appears damaged or hazardous.
- Get witness information. Ask other passengers and bystanders for names and phone numbers. Witness memories fade quickly — the sooner statements are recorded, the more reliable they are.
- File an incident report. Report the accident to RTD or the railroad company and request a copy of the report.
- Contact a personal injury attorney immediately. Your attorney will send a formal preservation letter (spoliation letter) to RTD and any other involved parties, demanding they retain all evidence related to the incident.
- Preserve your own evidence. Keep all medical records, receipts, the clothing you were wearing, and a written account of what happened while your memory is fresh.
The Spoliation Letter: Your Most Important Legal Tool
A spoliation letter is a formal legal demand sent to the railroad company, transit agency, and any other potentially liable parties. It instructs them to preserve all evidence related to the incident, including surveillance footage, maintenance records, event data recorder data, and employee records.
Once a party receives a spoliation letter, they have a legal obligation to retain all relevant evidence. If they destroy or alter evidence after receiving the letter, they may face sanctions in court — including adverse inference instructions that tell the jury to assume the destroyed evidence was unfavorable to the railroad.
This is why contacting an attorney quickly is so important. Every day that passes without a preservation letter increases the risk that critical evidence will be overwritten or discarded.

Frequently Asked Questions
What evidence should I collect after a train accident?
Photograph the scene, your injuries, and any visible hazards. Get contact information from witnesses. File an incident report with the transit agency. Keep all medical records and receipts. Note the date, time, weather conditions, and train number or line. Your attorney can then subpoena surveillance footage, black box data, and maintenance records from the railroad company or RTD.
How long does RTD keep surveillance footage?
RTD surveillance footage retention periods vary but are typically 30 to 90 days before being overwritten. If you are injured in a train accident, it is critical to have your attorney send a formal preservation letter to RTD as quickly as possible to prevent this footage from being destroyed.
What is a spoliation letter and why does it matter?
A spoliation letter is a formal legal demand sent to a party instructing them to preserve specific evidence related to a potential claim. In train accident cases, this letter tells RTD or the railroad company to retain all surveillance footage, maintenance logs, operator records, event data recorder data, and inspection reports related to the incident. Failure to preserve evidence after receiving this letter can result in legal sanctions.
Can event data recorders help prove my train accident case?
Yes. Modern trains are equipped with event data recorders (similar to airplane black boxes) that capture speed, braking patterns, signal responses, and other operational data. This information can be critical in proving operator error, mechanical failure, or inadequate braking. Your attorney can subpoena this data during the investigation phase.
