i find all kinds of things on my local RR track. i get all the spikes i can carry, the plates that go under the tracks, large bolts and nuts, the bent bars that go to something( not sure what they are but they are good 1/2 in bar stock) and different bars that i find. the scrap yard that i go to has all kinds of stuff including piles of bar stock in 20ft lengths. i picked up some 3/4 by 1/8in stock for candle holders and a 10in piece of one inch round bar to make a tomahawk drift. i think that i am going to make the guy at the scrap yard a spike knife and maybe he will put some cool stuff that he gets aside for me.
