Kusan K-Series Alco Locomotive Weights
Kusan K-Series Alco locomotives are lightweight. To improve pulling power, rubber traction tires and weights were added at the factory. The photo on this page shows the factory-installed weights. They appear to be pieces of large nails. The weights are located in a recessed area of the center chassis. This is the reason some Alco locomotives have a pronounced rattle when shaken.
