Brake blocks are an essential safety feature of locomotives and rolling stock, allowing for controlled and efficient braking of the train. Traditionally brake blocks were made of cast iron and had a curved face that fit against the wheel tread, providing friction to slow down the train.
PNP Railways have recreated the brake blocks of the past using modern manufacturing techniques.
PNP Railways Standard & Narrow Gauge Brake Blocks
- Our brake blocks are are injection moulded in a grade of nylon which is filled with glass beads to a level of 40%. These beads are very small and provide the braking medium with the plastic acting as a carrier
PNR-1D - Standard Scale Brake Blocks - designed to suit a 4" - 5”-wheel diameter.
PNR-1E - Narrow Gauge Brake Blocks - designed to suit 5" - 6" wheel diameter.
- The blocks are supplied as a set of 4, ready to fit, only requiring the pin hole to be drilled.
- It is important to remember to periodically inspect the blocks and replace as needed to ensure that the brakes are functioning properly and can effectively slow down or stop the train in the event of an emergency.
