S&T Cover are championing LID-UP, a simple and yet effective Safety Focus to ensure “Everyone Home Safe Everyday”. Every S&T Cover Operative will not walk by, once a week they will put a dislodged Trough Lid back into place, thus reducing Hazards, Accidents and improving Operational Productivity and Safety throughout the Railway Network.


S&T Cover Ltd partnered with Kier Group to deliver a series of Network Rail’s “Stay Safe at Level Crossings” presentations in Littlehampton Schools. The interactive presentations, which were very well received, promoted safety behaviours and awareness by engaging the children in a Safety Poster Competition, with the aim to reduce accidents and anti-social behaviour at one of the busiest crossings in Britain. This initiative was featured in the Feb/Mar 2018 edition of Rail Technology Magazine (RTM).
