Every railroad and water carrier shall adopt reasonably adequate safety measures and install, operate and maintain reasonably adequate safety devices for the protection of life and property to the extent consistent with federal law. If after investigation the office shall determine that public safety requires it, the office may, if permitted under federal law, order a railroad to install, operate and maintain a block system or order a railroad or water carrier to install, operate, and maintain any other safety device or measure as may be necessary to render the operation of the railroad or water carrier reasonably safe.
