Abstract

Abstract A railroad car having at least one deck for supporting and transporting four-wheel vehicles such as automobiles and trucks including a track secured to the deck longitudinally of the railroad car; a pair of movable chock blocks for each vehicle transported on the deck to secure the vehicle against longitudinal movement; each chock block including a bar with a first end and a second end; and pins on the bar first end for removably and releasably engaging holes in the track when the bar is substantially lateral to the track and spaced above the deck to prevent the bar first end from moving lateral to and longitudinally along the track and from being displaced out of lateral position to the track by pivoting, relative to the track, about a vertical axis, said means permitting ready release of the bar first end from the track so that the bar first end can be moved along the track.
