5. Save energy with self-regulating points heating
up to 30% less

Rail networks are setting ambitious targets to reduce CO₂ emissions with the move towards net zero. To meet these targets it is crucial to find ways to reduce energy consumption.
GrayBar’s Self Regulating Points Heating system is the perfect solution to reduce both operational expenditure and energy consumption. Our Points Heating system uses intelligent polymer heater strips which only heat the cold part of the rail, using up to 30% less energy compared to constant wattage points heating. Combined with a long life (40+ years) this makes it the obvious choice for reducing the whole life cost of points heating.

8. GrayBar have successfully designed and manufactured many innovative products to supply projects to Network Rail and TFL, including:


GrayBar were selected to design and build the Points Heating System for HS1 High Speed Rail Link. The GrayBar system had two variants, the first one with both the control and six 6.5KVA integral transformers, and the second version having a separate transformer cubicle, housing 12 integral 6.5 KVA transformers.


Crossrail engaged with GrayBar at a very early stage to look at using the GrayBar Self-Regulating Points Heating System on this prestigious project. On many of the sites selected, space was at a premium, and having all of the control gear and transformers in one cubicle was the ideal solution. Collaborating closely with Crossrail’s Design Team, GrayBar fine-tuned their system to meet the specification required.
