A band saw for sawing a rail of a track is configured for fastening to a vice which can be clamped onto the rail and is provided with a feed device. The band saw includes a frame in which four saw band rollers are mounted. A saw band is stretched around the four saw band rollers and, in a recess of the frame, the saw band is twisted into a sawing plane by guiding elements. Due to the utilization of four saw band rollers, there is little wear of the saw band, resulting in a longer service life.

A cold saw module may be a rail saw module that includes a cold saw configured to cut a railway rail along a cutting path, a rail alignment clamp configured to grip the railway rail near the cutting path, a feed actuator to drive the cold saw along the cutting path, and a module coupling element configured to selectively couple to a mating module coupling element of an articulated arm and/or a tool adapter. Cold saw modules may be used to cut metal workpieces such as a railway rail. Cutting a railway rail may include positioning the cold saw module at a cutting site along the railway rail installed in a railway, clamping the cold saw module to the railway rail, and cutting the railway rail at the cutting site with the cold saw module while the cold saw module is clamped to the cutting site.
