On the day I visited, there were two machines on the siding. One was Knox Kershaw KBR 925 Ballast Regulator, the other a Harsco Rail 6700 Production/Switch Tamper.
The KBR 925 is designed for ballast work on all types of track. Superb visibility in every direction, especially the wing areas, makes it the ideal machine for final profiling. The one pass transfer plow used in conjunction with the wing makes transferring from shoulder to shoulder a one pass operation, while leaving one shoulder profiled. The reversible wings allow work in either direction so no movement is lost. The broom box gives excellent service life, and the standard reversing valve allows ballast to be swept away from switches and road crossings.
Broom:
Sweep width – 110” (2794 mm); reversible; single motor belt drive. Deflector includes high performance baffles for quick transfer of excess ballast to the track shoulders. Deflector assembly is hydraulically raised and lowered. Available options include water misting dust suppression.
The 6700 Tamper is the latest model of Harsco Rail’s well-known production and switch tamper. Harsco Rail’s 6700 Tamper is a high tech, refined machine known for top quality production, switch tamping, and transit system work. Harsco’s Positive Displacement Workhead Technology is an available option for this machine. Harsco Rail tampers are designed to meet local standards of the customer.
