There is provided a railroad track asset surveying system suitable for mounting to a conventional passenger or freight vehicle. Image capture sensors including linescan, areascan and laser imaging devices are mounted on a railroad vehicle. A location determining system, such as GPS and/or a track position sensor, is provided for images captured by the image capture sensor. An image processor provides an asset classifier for detecting assets in captured images and classifying the detected assets by assigning an asset type to the detected asset from a predetermined list of asset types according to one or more feature in the captured image. The image processor also provides an asset status analyser for identifying an asset status characteristic and comparing the identified status characteristic to a predetermined asset characteristic so as to evaluate a deviation therefrom. The system may automatically survey a variety of assets, including vegetation, in a scene surrounding the rail track. The system may be provided as a singular assembly or module for mounting in a forward facing direction to a conventional vehicle.
