The following components are installed on the machine:
- diesel power plant with a capacity of at least 400 kVA,
- two-axle carriages,
- traction motors with thyristor speed control, which provides a smooth acceleration and movement of the machine with a trailed train set of up to 130 tons.
The machine includes:
- modern rail welding machine K 922-1 with an upset force of 120 tons, which allows to weld rail inserts without deformation of the insert in the form of a “loop”,
- press for testing control welded joints, a device for pulling up rails, technological equipment.
