1. A method, comprising: capturing, with a first image capture device mounted on a mobile platform configured for movement along a railway comprising one or more rails, a series of position reference images as the mobile platform travels along the railway; identifying, in at least one position reference image, a visual target positioned proximate to the railway; determining a distance from the mobile platform to the visual target; calculating, at a computer system, a location of the mobile platform on the railway, based at least in part on the determined distance from the mobile platform to the visual target; capturing, with a second one or more image capture devices, one or more railway images of the one or more rails; performing, at the computer system, photogrammetric analysis on at least one of the one or more rail images to identify a rail configuration of the railway, wherein the railway comprises a plurality of rails and the photogrammetric analysis on at least one of the one or more rail images comprises: identifying, in the at least one image, a location of a first edge of a first rail; identifying a location of a second edge of a second rail; and calculating a distance between the rails, based on the location of the first edge of the first rail and the location of the second edge of the second rail; associating the rail configuration with the location of the mobile platform on the railway; and storing, in a data store, a data record comprising data about the rail configuration and the associated location of the mobile platform.
