A Denver light-rail injury is not a bigger car crash, and it is not the same file as an RTD bus claim. The vehicle may be a light-rail car on the E Line or the W Line, or a commuter-rail train on the A Line, the B Line, or the G Line. The injured person may have been a passenger thrown inside the car, a pedestrian hurt at a platform edge, or a driver struck at a grade crossing. If the Regional Transportation District or another public entity operated the train, the Colorado Governmental Immunity Act can require a written notice of claim within 182 days under C.R.S. § 24-10-109(1). The statute calls that filing a jurisdictional prerequisite. A police report or an RTD incident number is not that letter. This page is for people looking for a Denver light rail accident lawyer after an RTD rail injury — not a timetable.
The legal object changes with the facts. C.R.S. § 24-10-103(2.7) defines “motor vehicle” to include a light-rail car or engine owned or leased by a public entity. That is why an RTD rail crash can open the motor-vehicle waiver in C.R.S. § 24-10-106(1)(a). A fall on a station platform, a gap at the car door, or a wet boarding edge may instead be a dangerous-condition claim under C.R.S. § 24-10-106(1)(c) or (d). Same agency. Different statutory door. Either way, the 182-day notice still has to be served on the right desk. Our Denver bus accident lawyer page is the pillar for RTD transit claims. The RTD bus accident claims guide walks the notice and evidence problem on buses. The Colorado notice of claim article is the full C.R.S. § 24-10-109 teardown. This article owns the rail-specific job: platform injuries, crossing risk, the A/B/G/E/W lines, and the light-rail definition the bus pages mention only in passing.
A light-rail file is not a bus file with a different vehicle
RTD buses and RTD trains share an agency name, a public-entity notice clock, and a habit of overwriting video. That is where the overlap stops. A bus claim often turns on hard braking, a curb-side ramp, a right-hook turn, or a collision with another motorist. A rail claim turns on a moving consist, a platform edge, a crossing gate, or a station that is also a public building. The evidence map is different. The waiver theory can be different. Treating the file as “another transit crash” is how the wrong records get requested and the right deadline still gets missed.
The statute itself draws the line. C.R.S. § 24-10-103(2.7) does not leave lawyers to argue whether a light-rail car “counts” as a motor vehicle. It writes the car and the engine into the definition when a public entity owns or leases them. That sentence is why an on-train injury can be analyzed under the motor-vehicle waiver in § 24-10-106(1)(a) instead of being dismissed as an unlisted transit event. It is also why a platform injury should not be forced into that same box. If the harm happened because of a condition of the station, the boarding edge, or the adjacent street, the live question is whether a dangerous-condition waiver exists under § 24-10-106(1)(c) or (d). Immunity is the default. The waiver is the exception. The notice is required in either path.
The 182-day CGIA notice still controls the rail claim
Colorado’s ordinary motor-vehicle lawsuit deadline is generally three years under C.R.S. § 13-80-101. Claims against a public entity run a second, shorter clock. C.R.S. § 24-10-109(1) requires a written notice of claim within 182 days after discovery of the injury, whether or not the claimant then knew every element of the claim. Compliance is a jurisdictional prerequisite. Failure forever bars the action against that public entity. That rule is the same for an RTD bus and an RTD train. The rail facts do not soften it.
People lose these claims by thinking they already gave notice. They told the operator. They called customer service. They have a police report. They spoke with a claims representative. Those steps may prove the event happened. They are not the statutory letter. The notice must contain specific fields, and it must reach the governing body or the attorney representing the public entity by registered or certified mail, return receipt requested, or by personal service. Hypothetical only, not a Conduit result: a passenger who reports a platform fall to RTD on day 10 and starts physical therapy on day 40 still has not served the § 24-10-109 notice. If the letter is mailed on day 183, the court never reaches whether the platform was dangerous.
“Compliance with the provisions of this section shall be a jurisdictional prerequisite to any action brought under the provisions of this article, and failure of compliance shall forever bar any such action.” — C.R.S. § 24-10-109(1)
What the notice must contain
C.R.S. § 24-10-109(2) is a checklist, not a suggestion. The notice shall contain five items: the name and address of the claimant and of the attorney, if any; a concise statement of the factual basis, including the date, time, place, and circumstances; the name and address of any public employee involved, if known; a concise statement of the nature and extent of the injury; and a statement of the monetary damages requested. For a rail file, “place and circumstances” should identify the line, the station or crossing, the car or train if known, and whether the injury happened on board, on the platform, or in the street. Courts have been more flexible about contents than about the 182-day deadline. A thin letter that still identifies the event may survive. A perfect letter mailed on day 183 does not.
| C.R.S. § 24-10-109(2) | What the notice must say | Rail-specific detail that helps the entity investigate |
|---|---|---|
| (2)(a) | Claimant name and address; attorney name and address if any | Tells RTD or the other public entity who is claiming and where to respond |
| (2)(b) | Concise factual basis: date, time, place, and circumstances | Line letter, station or crossing, inbound or outbound, car/train number if known |
| (2)(c) | Name and address of any public employee involved, if known | Operator or station employee only if known; do not guess a name |
| (2)(d) | Concise statement of the nature and extent of the injury | Separates a bruise from a fracture, a concussion, or a death claim |
| (2)(e) | Statement of the monetary damages requested | A number or a stated range; this is notice, not a settlement demand |
Who receives it, and the 90-day wait before suit
C.R.S. § 24-10-109(3)(a) splits the addressee. State claims go to the Attorney General. Claims against any other public entity go to that entity’s governing body or the attorney representing the entity. The notice is effective on registered or certified mail, return receipt requested, or on personal service. A notice properly filed with an agent listed under C.R.S. § 24-32-116 also satisfies the section. After a timely notice, C.R.S. § 24-10-109(6) still bars filing the lawsuit until the entity denies the claim or 90 days pass, whichever comes first. The lawsuit itself then has to be filed inside the ordinary Title 13 window. Public-entity judgments are separately limited by C.R.S. § 24-10-114. Those are statutory caps, not case results. The 182-day notice guide walks the contents, the addressee, and the late-notice cases in full.
| Clock | Deadline | Statute |
|---|---|---|
| Written notice of claim | 182 days after discovery of the injury | C.R.S. § 24-10-109(1) |
| Earliest lawsuit | Denial, or 90 days after the notice, whichever is first | C.R.S. § 24-10-109(6) |
| Motor-vehicle lawsuit | Generally 3 years from the crash | C.R.S. § 13-80-101 |
| Public-entity judgment limits | Statutory caps, separately adjusted | C.R.S. § 24-10-114 |
Platform injuries are their own proof problem
Not every serious rail injury happens inside a moving car. People are hurt at the platform edge, in the gap between the car and the platform, on stairs and ramps, and in the crush of a crowded boarding. Those files look like premises cases on day one and like transit cases once the operator’s records arrive. The questions are practical. Was the gap wider than a rider could reasonably manage? Was the edge marked? Was the platform wet, icy, or broken? Did the doors close on a person who was still boarding? Did the car move before the rider had a chance to stand clear?
Boarding, the gap, and the platform edge
A gap injury is easy to understate and easy to lose. The rider may think it was clumsiness. The operator may treat it as a customer-service incident. The medical picture — a fractured tibia, a torn shoulder, a concussion from the fall to the platform — can take days to declare itself. Meanwhile station video can overwrite on a routine cycle. The claim is not that every boarding is dangerous. The claim, when the facts support it, is that a known condition of a public station or a public employee’s operation of the car created a risk a reasonable operator would have addressed. That is a dangerous-condition or operation question, not a product-defect speech.
Collect what you can safely collect: the station name, the line letter, the time, the inbound or outbound direction, photographs of the edge and the gap, and the names of anyone who saw the fall. Then treat the 182-day clock as live. A platform injury against RTD is still a government claim. The Denver bus accident lawyer page covers boarding and ramp injuries on buses; the same urgency applies at a rail platform, with station cameras and platform logs in the preservation letter instead of a bus-door camera alone.
Crossings and grade-crossing collisions
Denver-metro rail does not stay in a tunnel. Commuter-rail corridors in particular run at grade through streets and industrial edges. A crossing collision can involve a private driver, a pedestrian, a cyclist, and an RTD train in the same few seconds. The first police report may name only the motorist. The first insurance call may treat it as an ordinary intersection crash. The rail records — event recorder, crossing-signal logs, onboard forward video, dispatcher audio — sit with the agency unless someone asks for them before they age out.
Who the crossing file can name
Liability at a crossing is a stack, not a slogan. A private driver who drove around a gate or stopped on the tracks may carry ordinary auto liability. RTD may be in the case if the operation of the train or a dangerous condition of the crossing is in play. A city or county may own the intersecting street. A contractor may have been working on the gates or the pavement. Each additional public entity is another 182-day notice analysis. Mostellar v. City of Colorado Springs is the reminder, already discussed on the notice blog, that learning the second public entity late does not restart the clock. Calendar every plausible public defendant inside 182 days rather than waiting for someone else to name the right one.
- Private motorist: ordinary auto coverage and the three-year motor-vehicle filing window under C.R.S. § 13-80-101.
- RTD train operation: motor-vehicle waiver analysis under § 24-10-106(1)(a), plus the § 24-10-109 notice.
- Crossing or street condition: dangerous-condition analysis under § 24-10-106(1)(d), still with notice.
- Pedestrian or cyclist in the crossing: comparative fault under C.R.S. § 13-21-111 may be raised; it is a damages issue, not a reason to skip the notice.
RTD rail lines A, B, E, G, and W — enough geography to identify the file
This is not a timetable. It is the minimum geography a notice and a preservation letter need. RTD’s rail system mixes light rail and commuter rail. The E Line and the W Line are light rail. The A Line, B Line, and G Line are commuter rail. The CGIA definition in § 24-10-103(2.7) speaks of a light-rail car or engine; the notice analysis should still be run when a commuter-rail train is owned or operated by a public entity. Do not decide the waiver from the line letter alone. Decide it from who operated the vehicle and where the injury happened.
| Line | What it is | Corridor a claim file actually uses |
|---|---|---|
| A Line | Commuter rail | Denver Union Station to Denver International Airport; grade crossings and station platforms along the northeast corridor |
| B Line | Commuter rail | Denver Union Station to Westminster Station |
| G Line | Commuter rail | Denver Union Station to Wheat Ridge / Ward Road, through Arvada |
| E Line | Light rail | Southeast corridor along I-25 between Union Station and RidgeGate Parkway |
| W Line | Light rail | West corridor between Union Station and the Jefferson County Government Center–Golden station |
Union Station is the common downtown node. A platform injury there can look like a downtown premises file until the operator records show which line, which car, and which camera. An A Line crossing injury in the airport corridor can look like a private-driver crash until the crossing-signal log arrives. Name the line in the notice when you know it. If you do not know it, say so and describe the station, the time, and the direction rather than inventing a letter.
Who may be liable — and who is only in the first story
RTD is often the name on the car. It is not always the only responsible party, and it is not always the party a private adjuster wants to talk about. A serious rail file asks who controlled the risk: the operator of the train, the public entity that owns the station or the street, a maintenance or construction contractor, another driver, or some combination. Sorting that stack early is how you find every deadline and every coverage or self-insurance source. The RTD bus claims article makes the same point on buses. On rail, add the platform owner, the crossing maintainer, and any contractor who had the station or the gates that week.
Public entity, private contractor, other driver
A public-entity defendant brings CGIA notice, possible immunity, and the § 24-10-114 caps. A private contractor may not be a public entity at all, which means the ordinary two-year or three-year Title 13 deadline may control that defendant while the 182-day notice still controls the agency. A private driver at a crossing brings an auto policy and, often, a comparative-fault argument. Mixed-operator files are the ones that die from a single calendar. Serve the public-entity notice first. Preserve the rail records second. Then sort the private coverage. Founding attorney Elliot Singer, a former Colorado Assistant Attorney General, has seen how public entities evaluate notice and immunity from the government side. That background is useful on an RTD rail file. It is not a guarantee about any case.
- RTD / public-entity operation: speed, signal compliance, door timing, boarding, or failure to keep a clear platform edge.
- Station or crossing condition: ice, broken edge, unmarked gap, lighting, or a crossing surface that physically interferes with traffic.
- Maintenance or construction contractor: work on gates, pavement, or a station that created the condition.
- Other motorist: a driver who entered the crossing, struck a pedestrian, or caused a secondary collision.
Colorado’s modified comparative negligence rule in C.R.S. § 13-21-111 can reduce recovery by the claimant’s share of fault and bars recovery at 50 percent or more. That is a reason to be careful with recorded statements about “I was in a hurry” or “I thought I could make it.” It is not a reason to delay the notice.
Evidence a rail agency can overwrite while treatment is still starting
Transit cases are evidence-sensitive. The best proof is often controlled by the agency: onboard video, platform cameras, event-recorder data, crossing-signal logs, dispatch audio, and incident reports. Those records do not wait for an MRI. A preservation letter that only asks for “bus video” will miss the file. Ask for the line, the car or train consist, the station or crossing, the time window, and every camera that could have seen the edge, the doors, the interior, or the street.
- Line letter, station or crossing name, direction, date, and exact time
- Onboard video, platform and station cameras, crossing cameras, and nearby business cameras
- Event-recorder, speed, and signal data; crossing-gate and warning-device logs
- Operator identity, training, prior incident reports, and dispatch communications
- Station inspection, snow/ice, and contractor work records for the platform or crossing
- 911 audio, police reports, body-worn camera, and witness names before people leave the platform
If you can safely photograph the car number, the station sign, and the edge or crossing, do it. If you cannot, counsel should still move the preservation request. Waiting until treatment is “done” is how a strong medical file arrives with no video.
Frequently Asked Questions
Is a Denver light-rail injury the same as an RTD bus claim?
No. Both can be public-entity claims with a 182-day CGIA notice under C.R.S. § 24-10-109. A light-rail or commuter-rail file also has to identify whether the injury was the operation of a light-rail car under C.R.S. § 24-10-103(2.7) and § 24-10-106(1)(a), or a dangerous condition of a platform, station, or crossing under § 24-10-106(1)(c) or (d). The evidence map — platform cameras, crossing-signal logs, event-recorder data — is different from a bus-door or hard-brake file.
What is the CGIA 182-day notice deadline after an RTD light-rail accident?
C.R.S. § 24-10-109(1) requires a written notice of claim within 182 days after discovery of the injury, whether or not you then knew every element of the claim. Compliance is a jurisdictional prerequisite. A police report, an RTD incident number, or a call to customer service is not the statutory notice. After a timely notice, § 24-10-109(6) still requires waiting for a denial or 90 days before filing suit.
Can I have a claim if I was hurt on a platform, not on the train?
Possibly, if the facts support a dangerous condition of a public building or public way, or if a public employee’s operation of the car contributed to the fall. Platform injuries are still government claims when RTD or another public entity controlled the station. They still need the § 24-10-109 notice. They are not automatically the same waiver theory as a passenger thrown inside a moving car.
Who can be liable after a Denver light-rail accident?
RTD may be one defendant. A private driver at a crossing, a city or county that owns the intersecting street, and a maintenance or construction contractor can also be in the case. Each public entity needs its own notice analysis. A private contractor or private driver may follow ordinary Title 13 deadlines instead of, or in addition to, the 182-day clock.
