Railroad crossing control system including constant warning time device and axle counter system

A railroad crossing control system comprising:

• a constant warning time device with a control unit configured to produce multiple signals, and
• a wheel sensing system comprising at least one sensor connected to a rail of a railroad track at a predetermined position,
• wherein the wheel sensing system detects a presence of railroad vehicle travelling on the railroad track such that the at least one sensor detects wheels of the railroad vehicle using electromagnetic fields,
• wherein the wheel sensing system provides speed values of the railroad vehicle to the constant warning time device,
• wherein the constant warning time device produces a constant warning time signal for controlling a railroad crossing warning device in response to receiving the speed values of the wheel sensing system, and
• wherein the railroad crossing control system further comprises:
• an evaluation module in communication with the wheel sensing system, wherein the evaluation module is adapted to count axles based on detection of the wheels of the railroad vehicle and to generate an indication that the railroad track is clear or occupied, and
• a converter, wherein the converter converts a direct current power supply of the constant warning time device from a first voltage level to a second voltage level for operating the evaluation module.
