GW608 CREDITION TO MELDON BETWEEN FORMER COLEFORD JUNCTION AND OKEHAMPTON
FROM 16:30 WEDNESDAY 22 SEPTEMBER 2021
Buttisland User Worked Crossing (UWC), located at 188m 03ch, will be upgraded to include red/green lights to signal to the users of the level crossing whether it is safe to cross using the Overlay MSL operating system. Telephones will be provided. The Overlay MSL system is being introduced to the area at User Worked Crossings with limited sighting. This system consists of red/green lights that indicate to the user whether it is safe for them to cross the railway. The lights are activated by wheel sensors that operate in a similar way to axle counters: when they detect a train they set the lights to red, after the train hits the strike out sensor the lights go to green. Would all staff please note that, like axle counters, using metal tools or simply passing by within a metre wearing safety boots can cause activation of these sensors, and should be avoided. If the sensors fail the lights go into dark mode, they will be reactivated by another train passing or can be reactivated through a manual reset.
