The Carriers Act of 1865 aimed to both limit the liability of common carriers for lost or damaged property and declare their liability for losses caused by negligence or criminal acts. It established that carriers would not be liable for losses of valuable goods like gold or jewelry unless their value was declared. Carriers could require higher payment for transporting valuable goods and those paying would be entitled to recover losses. The liability of railroad owners could not be limited by contract and they would be liable for negligence or criminal acts.
