I have a date nail that was given to me that's stamped 22 for 1922. We have a lot of old tracks around my town and so I went looking for some date nails. I found none. I only looked on the old sidings not the newer mainline tracks. Can anyone tell me where to look? I did notice that the rail plates were cast with a date on them. I found 1926, 1928 and up to 1944. Did some roads use these instead of date nails?
