Mixed bag of random thoughts here.
Has anyone seen new sodium streetlighting recently? It seems all the units doncaster are fitting are a noticeably lighter shade than standard high pressure units. Do these have a special name or gas mix? They aren't halide. Meanwhill down the road in Rotherham all their major routes and quite a few smaller roads are lit by leds.
New level crossing signals. The amber light comes on. Then both red lights come on together before they appear to stutter on and off clumsily then get into their rhythm. Why is this? Why can't they get the led units to flash properly from the start? This is on a totally renewed crossing and there's plenty of videos on YouTube too.
