In front of each wheel is a nozzle that uses compressed air to spray sand, which is stored in two tanks on the locomotive. The sand dramatically increases the traction of the drive wheels. The train has an electronic tractioncontrol system that automatically starts the sand sprayers when the wheels slip or when the engineer makes an emergency stop.

Green sand moulding is a traditional and widely used foundry process that forms the backbone of metal casting operations. It involves the creation of moulds using a mixture of silica sand, water, and a clay binder, giving it a greenish hue and earning its name. When compacted around a pattern, the green sand mixture retains its shape and …

Depending on the biopolymer concentration, the unconfined compressive strength of the sand treated with agar and starch biopolymers ranged from 158 to 487 kPa. Triaxial compression tests over a range of confining pressures also indicated that the biopolymers effectively increased the cohesion intercept and stiffness of the treated sand.
