An oncoming train alarm assembly for a railroad track includes a housing that defines an interior space. The housing is positioned on a first side of a railroad track. A power module and a microprocessor are coupled to the housing and positioned in the interior space. The microprocessor is operationally coupled to the power module. A transmitter and a speaker are coupled to the housing and operationally coupled to the microprocessor. The microprocessor is positioned to command the transmitter to transmit a photoelectric beam. A receiver is positioned on a second side of the railroad track. The receiver is operationally coupled to the microprocessor and aligned with the transmitter. The receiver is positioned to detect the photoelectric beam and to signal the microprocessor in event of a blocking of the photoelectric beam, positioning the microprocessor to actuate the speaker to sound an alarm to warn persons of an oncoming train.
