1. A derail assembly for derailing a wheel of a railway vehicle movable along a rail, said rail having a substantially straight linear axis, a field side and a gage side, wherein said rail is securely and transversely mounted on a top of spaced ties, said ties each having an upright top side and a bottom side, said rail having an upper head and a lower flange interconnected by a central upright, unitary riser, said derail assembly comprising, in combination:
(a) a box assembly comprised of a generally horizontal, planar, mounting plate dimensioned to be positioned on and attached on the upright top side of two spaced ties, said mounting plate including first and second vertical parallel, laterally spaced guide plates spaced no greater than the spaced ties, said guide plates including in combination a pivot hinge connection element, said hinge connection element including pivot slots with a pivot axis generally parallel to said linear axis of a rail;
(b) an elongate shoe including an elongated rigid derail plate having an upper side and an underside, said underside capable of being in contact on an upper head of a rail, said elongated rigid derail plate further having a wheel entrance end and a wheel exit end being longitudinally spaced from said wheel entrance end, said derail plate further including an attached transversely projecting pivot panel arm with a pivot axis parallel to the box assembly pivot axis slots of the guide plates, said pivot axis of said projecting arm and said pivot axis of said slots of said guide plates are generally parallel, coextensive and simultaneously adjustable upon pivot panel of the pivoting arm of said shoe positioned in the slots between the parallel guide plates of the box assembly; and
(c) fasteners for attaching the mounting plate to spaced ties;
wherein each vertical guide plate has an upper front end with a reduced height front section that is dimensioned to avoid interfering with the shoe when the shoe is located on a rail.
