These simple but critical terminal boxes ensure that railway points have sufficient heat to stay safe and efficient in freezing weather. Working for McNicholas and Network Rail, we have now supplied over 1,000 of the units, which connect the points' heating elements during Network Rail's transition from gas to electrical heating. It may be a simple product, but our ability to make a high volume of bespoke boxes at the right price, and to a tight delivery schedule, has helped ensure the projects' success.
