Typical Sizes of Signals

[Anonymous]

What is the typical mast height for grade crossing signals?

According to the Western Cullen Hayes website I have referred to recently, the minimum mast height is 15' 6". The height should go up relative to the length of gate arm and need for wind bracing requirements, etc. There are other sites you could try using a search engine like Google. Hope this helps.
