The Pandrol Balise Protection Device (BPD) is a specialist product designed to protect balises (transponders) from damage due to ice impact (ice lumps falling from passing rolling stock).
By positioning balises accurately and protecting them from ice impact damage, the BPD improves signalling system reliability and track safety.
Improved signalling system reliability means that there are fewer interruptions to train operations, enhancing passenger service.
Network operators can achieve significant financial benefits as a result of operational efficiency and increased passenger numbers.
Ease of installation and maintenance makes the BPD system a cost-effective, time-efficient option.
Safe to install and providing an anti-trip, non-slip walkway, the BPD contributes to the safety of track workers.
Resilient and resistant, the BPD is extremely durable and offers a cost-effective long-term solution.
The BPD has been proven to withstand multiple ice impacts at high speed, deflecting ice that detaches from trains and protecting the balise.
Testing has shown that the BPD is effective at protecting balises on high-speed tracks up to a line speed of 300km/hr.
The BPD is lightweight, portable and is easily mounted on the sleeper (tie) using two screw anchors. For maintenance or replacement, the complete unit and/or lid can be removed using simple hand tools.
Pandrol’s BPD is compatible with a range of sleepers. Positioning the balise over the sleeper and maintaining a narrow design means that the product is compatible with automatic track tamping machinery.
The device is shock and vibration resistant to EN50125-3 standard. It also has high resistance to chemical and climatic changes and offers compliance to UL94-VO for flammability.
As well as protecting the balise from impact, the BPD offers a non-slip, anti-trip profile for people walking along the track.
The On-Sleeper Beam is mounted over the sleeper onto the existing rail fastening, eliminating the need to drill the sleeper.
All of the magnets can be fitted using the Pandrol Rapid Fit Frame System, with a typical installation time of 20 minutes for a double magnet assembly.
The Clamp Beam is mounted between sleepers on ballasted or slab tracks and is retained by clamping to the feet of the running rails.
