Railfan Technology > Lindsay counterweighted tilting signal masts.

Are any of these devices deployed on US railroads? If so, I'd be grateful to know where.

I don't know of any but it looks like a good idea.
When it is lowered you would have to be careful that there are no
trains approaching. I wonder how accurately it would retain its point of focus
after raising.

I believe that LED's in an array are much brighter have a wider field of view than the old incandescent/mirror/lens system that had to be precisely aimed, that is how they get away with the cheaper installations that we see now that only have to be aimed "in the ballpark". In the UP Signal Dept. I aimed a lot of the old ones, kind of like a crosshair gunsight, I don't even know if the new signal heads have an aiming system. I have noticed the PTC antennas next to signal houses are a double square-stock mast with a hinge in the middle, so they can be lowered and serviced from the ground. === === = === JLH

Looking at the headline, I thought you were talking about HO models...
