An overhead railway and trolley for transporting miners out of a mine. The railway is formed by connected rails that are mounted to a roof of a mine. The trolley is mounted to a bottom flange of the rails and includes wheel assemblies having at least two wheels mounted side-by-side, and each is configured to engage and roll along a top surface of the bottom flange. The trolley has a clicker that is configured to engage protrusions extending away from the bottom flange. The clicker permits the trolley to travel out of the mine but prevents it from traveling into the mine. The trolley also includes a pair of handles that are configured to be gripped by a miner standing on a floor of the mine as he travels from the beginning of the railway to the ending (i.e., the egress direction).
