In a method of determining the location of a locomotive when GPS signals are not available, triangulation between one or two radio transmitters and, respectively, two or one radio receivers mounted on the train can be used. In the method, the distance between each radio transmitter and each radio receiver can be determined according a number of cycles of the radio signal generated by the radio transmitter that are received/counted by the radio receiver. The radio signal can also have modulated thereon the geographical location of the radio transmitter, which location can be demodulated by the radio receiver. Utilizing the demodulated geographical location of each radio transmitter and the distance between the radio transmitter and each radio receiver, triangulation can be used to determine the geographical location of the train.
