The wear of the valve motionparts is mostly caused by their own weight, assuming that the lb. The main drivers were several hundred pounds lightas to counterbalance, even in balancing the revolving weights,and two counterweight bobs weighing 1,500 lb. each had beenplaced on the main axle between the boxes. This made the deadweight on the main drivers excessive. The railroad company 166 RAILWAY AGE GAZETTE. MECHANICAL EDITION \ 89.
