A tie having a non-linear keyway under the overlying rail to provide support to restrain lateral and longitudinal movement of the rail. A fastening system to hold rails down on a tie comprises a rail plate that may be fastened to the tie within the keyway. The fasteners are protected to avoid damage in case of a derailment or other adverse conditions. Also disclosed are visual inspection mechanisms to assist with determining whether a fastening system is securely attached to the tie.
