Compressed Air Locomotive

The first compressed air locomotive was building about 1886. This worked with a pressure of 8 to 10 kg/cm2, while the air is expanded in a cylinder. After 1910, the one to two-fold expansion was introduced and the air pressure in the bottles was increased to 60 kg/cm2. This was because the limit laid down by the strength of riveted steel air bottles. After the seamless steel air pressure bottle was introduced the pressure could be increased to 200 kg/cm2.
The drive was just like steam locomotives developed through the two cylinders that the wheels through connecting and coupling rods propelled.
The pull of a compressed air locomotive was 1785 kg and was up to 60 coal trucks of 1.5 tons pull (and slow).

This compressed air locomotive stands for the training mine of young shaft to train miners in the Wilhelmina mine.
