The Series 670 Direct Sanding System for Locomotives includes a hopper with integral dust collection and a transporter to convey traction silica sand from a hopper direct to the locomotive. Included is a filling wand and counterweighted hose in addition to an automatic shut off valve to stop conveying when the locomotive is completely filled. The controls include an Allen Bradley programmable logic controller for all operating functions. The compact preassembled modular design fits easily between two rail lines and is completely dust tight and weather tight for even the most severe of applications.
