[TheForge] Question on RR steel.

[Jeff & Leslie]

Not too long ago someone was explaining the different pieces found along RR 
tracks.  I occasionally find pieces of round stock usually around 8 - 10" 
long and fonged to a square taper on one end.  Taper is about 4" long.  The 
rod is 1 3/4" in diameter.  I'd like to know what they are and what they're 
made of.  My spark testing skills tell me that they're probably metal.

Thanks,  Jeff in Tallahassee where it should get down to about 50 tonight 
for probably the last time till next fall
