I picked up this elderly crossing post sign (and matching RAILROAD CROSSING signs, which are not pictured) from the same fellow who sold me his C.N.R. CD 154s - the father of a very good friend of mine. T.H.& B.Ry. stands for the Toronto Hamilton & Buffalo Railway. I'm not sure when it was torn out exactly, Mike & Debbie might be able to help me with that one, but it's been gone for a while now. I figured a crossing post like this would be a somewhat rare thing to run by.
