8、y.SupersessionThis part of BS 376 supersedes BS 376-1:1951 (incorporatingAmendment No.1:1951), which is withdrawn.Relationship with other publicationsBS 376 is issued in two parts, namely: BS 376-1, Schematic symbolsPart 1 is for use on general plans, showing signalling requirements; it doesnot show
9、 the component parts of the apparatus to be used. BS 367-2, Wiring symbols and written circuitsPart 2 represents:a) the actual apparatus used, with its electrical connections; andb) simplified wiring diagrams.Information about this documentThis is a full revision of the standard, updated to current
10、practice.Presentational conventionsThe provisions of this standard are presented in roman (i.e. upright) type. Itsrequirements are expressed in sentences in which the principal auxiliary verb is“shall”.Commentary, explanation and general informative material is presented insmaller italic type, and d
11、oes not constitute a normative element.Contractual and legal considerationsThis publication does not purport to include all the necessary provisions of acontract. Users are responsible for its correct application.Compliance with a British Standard cannot confer immunity from legalobligations.BRITISH
12、 STANDARDBS 376-1:2012ii The British Standards Institution 20121 ScopeThis British Standard specifies the symbols to be used on railway signalling plansbut does not provide guidance on their application.This British Standard does not apply to tramways operated on line of sight orusing highway signal
13、s. It does not include proprietary systems and specializedapplications.NOTE 1 The symbols in this British Standard provide for apparatus in general use.They have been designed so that they can be combined together where one doesnot represent the complete device. In this British Standard, where certa
14、in elementsare added for illustrative purposes, they are shown by dashed lines. If additionalinformation is required to support the symbol, a “#” may be used to reference anote on the plan.NOTE 2 The symbols are shown relative to the drivers point of view; on actualplans the symbols are rotated.NOTE
15、 3 The size of symbols are drawn in proportion but are not necessarily relativeto one another nor give specific size to use.2 Terms and definitionsFor the purposes of this part of BS 376, the following terms and definitionsapply.2.1 normaldisplay or position of a piece of apparatus in its quiescent
