The new sections "A" and "B" of The
American Railway Association have not given as good results as was
expected of them, and the whole matter is yet under consideration. The
Committee reported as follows:[D]
"The instructions of the American Railway Association require us to
study the A. R. A. sections 'A' and 'B' in use and submit a single
type for standard. Owing to the conditions existing in 1908, very
little rail was laid, and practically none of the A. R. A.
sections, in such manner as to give the needed information. This
year, several roads have laid A. R. A. sections of rail, with a
view of determining the relative merits of the respective sections.
These rails have been in the track so short a time that we are not
justified in drawing any conclusions as to which of the A. R. A.
types, 'A' or 'B,' or if either, is better than the A. S. C. E.
sections.
"_Bulletin No. 116_, issued October, 1909, gives the statistics for
rail failures for six months from October 31, 1908, to April 30,
1909, as reported to the Committee.
