S. BalHet, Chairman W. J. Eck, p. P. Patenall, F. B. Wiegand Published by the Association 75 Church Street, New York PREFACE. The Manual ot the American Railroad Association, Signal Division was originally issned in 1912 by the Board of Direction of the Railway' Signal Association in accordance with the Constitution of that body Which required the Board of Direction to issue a Manual ot Recom- mended Practice containing the specifications and important standards of -the Association, also approved findings and conclusions Revisions and additions are made yearly by the Signal Division and such new matter is identified with the date approved by the Division The present edition, issued in two volumes, contains all matter which has received approval of the Railway Signal Association and ot the TITT " '"•'^'^ "^"^^ ^^^^^ ^^0. auickly the contents ot the specification section. The Standard Designs have been arranged numerically with an alphabetical and numerical ^ignaiLr"'"'/''' on Signaling m existence. Suggestions which will make the Manual more valuable will be gladly received by the Committee compiling the Manual, and it is hoped that readers discovering errors wiU kindly bring them to the attent of tne Committee. 1920.

E. standard for load loss. 1919. (d) Full load voltage ratio. The voltage ratio of the transformer shall be checked by impressing the rated voltage and frequency on the primary winding and reading all secondary voltages with rated current flowing in each terminal at the power factor specified on requisite sheet. The value obtained shall not vary more than two (2) per cent, plus or minus from the values given on the voltage diagram and requisite sheet. 19 18. (e) Polarity. Polarity of all transformers shall be checked as fol- Connect the relatively positive terminal of one winding to the relatively negative terminal of an- other winding, until all the windings are in series, impressing rated voltage across the terminals of the primary windings. The voltmeter connected between the two ends of all the windings in the series shall read the sum of all their voltages. i9i7« (f) Regulation. I. With no load the voltage of each of the wind- ings shall not exceed the full load value specified on requisite sheet by more than ten (10) per cent. 2. When calculated, the regulation for either the whole or part of the transformer shall be computed from the measured resistance and the reactance drop lows : 1918.

Core loss and exciting current shall be taken at any convenient ambient temperature, preferably not less than fifteen (15) degrees C. (59° F.). Core loss shall be measured with a watt meter at normal fre- quency and voltage, using power from generator giving a sine wave when such, is available. When a pure sine wave is not available, it shall be permissible to use any wave form which comes within the A. I. E. E. definition of a sine wave, adjusting the test voltage so that the core loss will be the same as with normal voltage and sine wave. Where voltage cannot be regulated by excitation of the generator, it must be done with auto-transformers and not by rheo- stats in series with the transformers to be tested. 3iiit£iaqm9J miolin: ^^^^ ^'^^ jjrn ad IlBita ^noiJouboiq lo iixi- IlG no ^bsm lisda woldd bdifiiamfina aiasT (b) ;2oI laqqoO .5 owi J8ift ariJ no sbsm ad Ilfiria i33* sriiwolloi ariT (9) 310D (b) *s ftdiB* !»d ilBiis Jxi9-nw3 gni^bx^ bns zsol mo3 .1 ton ^cicfBialaiq .^iislBi^qm^i in^idoiB •ruainavnoD '^i iBfmon ijs la^arn new b riJiw bsitiafi^m ad II. - • -■ ->nsg moil lawcq §ni8U ^as^^o^ bns v^n^ , iW .sldsIiBVB 8i jriioi/2 aadw avsw ^nis vr i-;sq ad IlBriE .ardBUBVfi ^on ai svbw L , r/icbiw asmoD ilDidw miol 9VBW yriB aair ol iniiaulbB ,9VBw ania - ' -^nnaab .3 .3 aB ^itw^ ^di ^d Iliw aaof aio. t oa ^s^iiov 9SB1IOV 9i3riW .3VBW 9Xiia bHB . ^^i. i lB«iion liJiw .oiB-iesnag aril lo nobBHoxa baiBlusai ad lonnsD ^d ion bHB 8-iaimolafisil-oJi/B dJiw anob ad ^ >i>hDa ni 5 American Railroad Association.

American Railroad Association SIGNAL division REVISION OF MANUAL, 1920. Approved by General Committee, Section II — Engineering March, 192 0. Approved by Executive Committee — May, 192 0. IMPORTANT— REA*D CAREFULLY. This Index has been prepared for the purpose of rearranging the Manual. Enclosed herewith will be found all subject matter adopted by letter ballot January 10, 1920, this material having been submitted for such action at the 1919 Annual Meeting. Prior to placing this matter in the Manual it should be carefully noted if all previous revisions have been inserted. If not, it is neces- sary that this be done prior to inserting the Revisions as of 1920. In order to make it clear the following guide is presented: In the First Issue of the Manual (1912), the Title Page will show, "First Edition, 1912." For 1913 the Title Page will show, "Second Edition, Revised 1913." For 1914 the Title Page will show, "Second Edition, Revised 1913." Revised 1914." For 1915 the Title Page will show, "Third Edition, Including subject matter approved January 5, 1915." For 1916 the Title Page will show, "Third Edition, Including subject matter approved January 10, 1916." For 1917 the Title Page will show, "Issue of 1917, Complete to December 31, 1916." For 1918 the Title Page will show, "Issue of 1918, Complete to December 31, 1917 " For 1919 the Title Page will show, "Issue of 1919, Complete to December 31, 1918." For 192 0 the Title Page will show, "Issue of 1920, Complete to December 31, 1919." It will be noted from above that there have been Additions and Revisions prepared every year since 1912, and these should be placed in the Manual in the order in which they were issued. It must be understood that such portions of existing matter now in the Manual that have not been affected by any revision, or have not become obsolete, are to remain intact; where revisions have been made to any sheet or sheets in existing specifications it will be necessary to substitute such sheet or sheets. The instructions, as shown on the following pages, are intended as a guide for inserting all new matter, substituting Revisions and removing all obsolete matter, if carefully followed will bring the Manual up to date. In order to differentiate between new, revised and obsolete matter, the following terms are used: INSERT. — New matter not previously shown. SUBSTITUTE. — Existing matter to be removed and revision in- serted. NO CHANGE. — Existing matter to be left in its present location. OBSOLETE. — Matter that has*either been incorporated elsewhere or superseded by new matter; such sheets are to be taken out. INSTRUCTIONS FOR INSERTING SUBJECT MATTER ADOPTED JANUARY, 1920. Care must be exercised where matter is to be substituted, to be sure that only the sheets affected by the change are removed before the new matter is inserted, as in some cases the original may consist of two or more sheets, whereas the revision may be confined to one sheet, or vice versa. , .„ , ^ ■ t„i,4.
