Techniques are disclosed for detecting and reporting railroad track anomalies. In one embodiment, a track inspection application is configured to receive images (or other sensor data) depicting a railroad track captured by cameras mounted on a train, compare the captured images with corresponding reference images (or other sensor data) captured from substantially the same locations and vantage points, and detect anomalies in the railroad track represented by differences between the captured images and corresponding reference images. In another embodiment, the inspection application may generate a three-dimensional (3D) model of the railroad track based on depths determined through, e.g., triangulation, and determine the railroad track's geometry from the 3D model. The inspection application may then detect anomalies associated with the track geometry, such as an incorrect distance between track rails or an incorrect overall location of the track, based on differences between the determined track geometry and a stored track geometry.
