A two-part rail saw assembly includes a clamp part and a saw part. The clamp part includes a clamp mechanism configured to clamp to a rail to be cut and a first connection interface coupled to the clamp mechanism. The saw part includes a second connection interface complemental to the first connection interface, the first and second connection interfaces configured to fixedly and positively interconnect, thereby to connect and fix the saw part relative to the clamp part. The saw part also includes a circular saw blade rotatably mounted to a saw hub, the saw hub being displaceably mounted relative to the second connection interface. The saw part further includes a feed mechanism configured to guide and displace the saw hub, and hence the saw blade, through a cutting path relative to the second connection interface, and thus relative to the clamp part when the parts are interconnected, and thus relative to the rail when the clamp mechanism is clamped thereto.

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.

A rail tool-holder cart (1) comprises a T-shaped support frame (2), a tool-holder arm, (12) rotatable about a vertical axis and tiltable between an upper position and a lower position and having a coupling interface for a tool (17, 17), a spring (19), which pushes the tool-holder arm permanently towards the upper position, so as to compensate at least one part of the weight of the tool (17, 17), as well as adjustment means (20) for adjusting the spring thrust (19).

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.
