In order to achieve improvement in reliability of a speed calculation device included in a railway vehicle while reducing cost increase due to redundancy of a device, a vehicle speed calculation device includes at least two shaft speed sensors, a non-contact speed sensor, a sensor receiving unit that receives at least two first detection values detected by the shaft speed sensor and a second detection value detected by the non-contact speed sensor, an estimated speed calculation unit that calculates an estimated speed at present time of the railway vehicle from a latest vehicle speed and acceleration of the railway vehicle, and a speed determination unit that determines a vehicle speed based on at least two of the first detection values, the second detection value, and the estimated speed. The speed determination unit determines the vehicle speed by selecting a required speed from at least two first speeds calculated from at least two of the first detection values, a second speed calculated from the second detection value, and the estimated speed based on an adhesive or non-adhesive state of a wheel including the shaft speed sensor.
