An introduction to Colour Light Signals 

Do you know what colour light signals are and what they mean?
In the second video looking at UK signalling we look at colour light signals, from the early examples to modern LEDs.
Do you know what a clearing point is or how different signals affect this?
As the series progresses we will move on to other safety systems, and how we apply these signalling principals in practice.
Please do not trespass onto the railway to conduct research - it is dangerous and a criminal offence to trespass on the railway.
There is a wealth of information available in books, on the internet or have a trip to a museum or heritage railway and speak to the volunteers who may be able to help.
Don’t forget to comment, like, share and subscribe, I look forward to hearing from you TUN.
