<p num="1"><br/><br/><br/><br/>A rail car apparatus includes a bridge mechanism pivotally attached to a <br/>middle rail <br/>wheel assembly. A front deck has a rear end pivotally attached to a front of <br/>the bridge <br/>mechanism, and a rear deck has a front end thereof pivotally attached to a <br/>rear of the <br/>bridge mechanism. A set of front rails is fixed to a top surface of the front <br/>deck, and a set <br/>of rear rails is fixed to a top surface of the rear deck. A set of bridge <br/>rails is fixed to the <br/>bridge mechanism between the front and rear rails and aligned therewith when <br/>the front <br/>and rear rails are aligned. The bridge mechanism, front rails, rear rails, and <br/>bridge rails <br/>are configured such that a rail vehicle can move along the front, bridge, and <br/>rear rails <br/>when the front and rear rails are oriented at an angle.<br/>
