The steam cylinders were located externally, unlike those on English locomotives, which avoided the need for a cranked axle that would have been expensive and difficult to manufacture. The steam engine was equipped with inside Stephenson valve gear

The locomotives did not have their own braking equipment. Braking could only be achieved using the hand-operated screw brake on the tender.
The locomotives had Kirchweger condenser
