| The end of this empty train is made up of about 50 VNSQB and VNLQB wagons. The letter V stands for 'mineral, ie coal'. The 3rd letter S or L refers to the wagon with the Westinghouse break, as these wagons are built as pairs with draw-bars between them, so only one unit has the full set of breake gear while the other just has hoses connecting it. [L is leader, with Westinghouse break. S is slave] |
