Appendix No. 18. Economy of Creosoted Ties
I inclose a calculation to show true economy in the use of preserved railway ties. This economy is not shown in the first cost, but in their longer life and in the relative annual cost per mile of track of preserved and unpreserved ties. I assume sixteen years as the probable service of creosoted soft wood ties, and eight years for unpreserved white oak ties. The former is the average life of creosoted Baltic fir sleepers on the railways in England, where the traffic is almost constant (see Bogart’s paper, Trans. Am. Soc. C. E., Vol. VIII, page 18); the latter is all which is claimed for the best oak ties in this country, and they are generally dozy and unsafe during the last two years of their service.
