About Petro & Harrington, LLC

The Midwest's Railroad Employee Advocates

For over 35 years, we have served as tireless advocates throughout the Midwest for railroad workers who have suffered all types of injuries and/or losses on the job. We have done so with the competence, sensitivity and aggressiveness it takes to develop an outstanding record of fair settlements and verdicts. If you or a family member are injured due to the negligence of a railroad employer, we want to help you. We have decades of experience in handling claims under the Federal Employers’ Liability Act (FELA), protecting the rights of railroad workers injured on the job.
Specific to our railroad practice, Dan Petro has been distinguished as Designated Legal Counsel for SMART-Transportation Division (former United Transportation Union). We also hold similar railroad union affiliations (Brotherhood of Railroad Signalmen, Academy of Rail Labor Attorneys). With these privileges, our law firm has assisted thousands of injured railroad employees in navigating the often difficult and unfamiliar legal process.
As always, our consultations are entirely free, and we don’t recover fees unless you win a verdict or settle your case.

  • How much will it cost me to hire the firm?

    We represent clients on a contingency fee basis. This means you do not have to pay us anything until and unless we obtain recovery for you. Importantly, our initial consultation is completely free. Our fee is a percentage of your recovery; this means your case is as important to us as it is to you.

  • How much is my case worth?

    Unfortunately, without knowing the facts of your specific case, it is impossible to estimate its potential worth. Personal injury cases can be worth hundreds of dollars or millions of dollars, and the difference may hinge on a particular fact in your case. The only way we can accurately estimate what your case might be worth is if you contact us and schedule a free consultation.

  • How long do I have to file my case?

    Each state has a different statute of limitations, or the length of time in which you are allowed to file a lawsuit, for personal injury cases. The statute of limitations can sometimes differ depending on the type of case and the jurisdiction where the case is filed. For example, some whistleblower cases must be filed within 180 days or less of the date of adverse employment action while many injury claims expire two years from the date of injury or death. In other states, and for different types of claims, the time period may be shorter or longer. It is important to contact us as soon as possible to begin a thorough investigation, preserve evidence and to determine what time limits apply to your case.

  • What can I expect if I decide to sue?

    If you decide to file a lawsuit, we will file the appropriate documents with the court on your behalf. This will initiate the legal process, and the responsible party will be notified. Often, the defendant’s insurance company will offer to settle with you for a lower amount than you deserve. If our evaluation of your case suggests you deserve more than what the defendant offers, we will take the case to trial and work tirelessly to obtain the maximum recovery you deserve. If the defendant does offer a reasonable amount, we may advise you to accept the settlement. Ultimately, the decision is yours and we will try the case in court if that is what you decide to do.
