Yellow triangle sign

[Anonymous]

Might be the start of cauthionary limits, or a warning that cautionary limits are one mile away.

As stated above certain signs vary from RR to RR.

Mile markers are pretty much standard, and many RR's use "W" and "X" signs. NS (Southern) had a different one: it looked like a roadside reflector, with two horizontal bars, a dot, and another horizontal bar for the standard grade crossing horn warning.

Railroad signage is fairly standard on either side of the Mississippi, but each RR is free to do what it wants and there are variations, especially in the "minor" signs like the flanger sign you saw.

Signal systems vary over a pretty wide range of light arrangements.

Karn,
Do you mean lineside signals or grade crossing signals? Either way there are some variations around the country/countries.

Usually Conrail used these signs to denote places where a snowplow operator needed to lift the plow for a crossing or other on track feature.

I have seen two yellow triangle signs on CSXT River Line. It is small and low in height. Anyone can tell what it is for?
