The present invention relates to a speed control method for an unmanned railway track inspection vehicle. The method includes the step of determining that the vehicle encounters a hazard. The method further includes the step of automatically, without human intervention, reducing the speed of the vehicle responsive to determining that the vehicle encounters the hazard. The speed control method is improved compared with known methods whereby the speed of the vehicle is automatically reduced when encountering the hazard so that the vehicle does not encounter the hazard at an unreasonably high speed. The hazard may be any one of a railway crossing, a trackside worker or trespasser, an unauthorized passenger, a track obstruction, a track gauge infringement, a track defect, a broken or absent rail, or a local hazard. |
