A weeding system for a railway weeding vehicle comprises:* at least one camera adapted to be mounted on a railway vehicle to acquire an image of a portion of a railway track while said railway vehicle is travelling on a train track, said image comprising a matrix of pixel values,* a spraying unit adapted to be mounted on said railway vehicle,* a control unit adapted to receive images from said camera, generate a weed species detection signal and selectively cause the spraying of a chemical agent by the spraying unit on the basis of said weed species detection signal.The control unit is adapted to execute in a running mode a training-based algorithm, the training being applied on a set of reference images labeled according to the effective presence of not of weed species in said images.Each of said reference images comprises a pair of a so-called nighttime image and a so-called daytime image of the same scene, in that said labeling is performed on the daytime images and applied to the corresponding nighttime images, and in that in the running mode, the algorithm receives nighttime real images.
