Not illustrated. 1919 edition. Excerpt: ...of bolts. I think we have in our laboratory a railroad spike for each concentration used in South Dakota for 5 years. At the end of those S years we all looked at them and we all decided that the spikes with 5% zinc chloride solution looked just as bright as the day we put them in. We all came to the conclusion that the corroded effect was due not to the zinc chloride but to dripping brine because we found just as many of these highly corroded spikes in untreated white oak ties on railroads that had never seen a zinc treated tie. I personally have never yet seen any reasons to change my opinion. MR. J. H. WATERMAN: What the doctor says I believe is literally true and I agree with him, but I have a reason for asking the question. The question is up today on the Burlington_ Road. Some men go out and they pull some spikes and they send them in and they say, "Here, look at that spike, all on account of the treatment of the tie." Now, I do not know what experience you men have had, but I will tell you what my observation has led me to believe in the last few weeks; first, that the Doctor is correct. I do not believe if the tie is properly seasoned before it is put in the track that the zinc will corrode the spike and destroy it; but I do find this, that rail runs and the spike that deteriorates first is the one at the angle bar. As the latter moves up and down it will chew off the head of the spike, and the men who are not experienced say it is zinc chloride. Any of you that go out on the railroad when you find the head of a spike for 2 inches or 3 inches practically destroyed, note if that is not a spike in the angle bar, and then stand by and see oneof thoselong trains with 85 or 100 cars go by and figure out how many times that...show more
