The Sectional Committee on Scientific and Engineering Symbols and Abbreviations, through one of its subcommittee, will shortly issue a report on Graphical Symbols for Traction and Railway Signaling. This report will be quite extensive. It is now being voted upon by the sub-group and as soon as the final approval is obtained it will be issued by the Institute in pamphlet form as a report for criticism and suggestion.
