A high security padlock for railroad switch locking stands, including a U-shaped shackle to extend through an aperture in an eye formation of a locking lever on the stand, and a padlock body having a pair of shroud shoulder formations projecting upwardly for unequal heights in enshrouding relation to three sides of the respective shackle legs. The shoulder formations extend into recesses in portions of the stand flanking the eye, when the shackle is in the eye, with the shorter shoulder spaced far enough to the confronting surface of the stand to permit insertion of the user's finger into holding relation with the shackle.
