Apparatus for Operation ofDerails at Crossings A situation somewhat analagous to the traffic condi-tions at congested points is found at busy surfacecrossings of steam and street railway lines. At theseplaces, in addition to the crossing gates, it is a safetyrequirement that the crossing be protected by derailingdevices. Where there is a man required to operate the. FIG. 18 -MECHANISM OF ELECTRIC TRACK SWITCH FORCONDUIT LINES. SOLENOID IS INCLOSED INCAST CYLINDER ON TOP gates, there is no added labor cost for operation ofderailing devices. The electric switch mechanisms lendthemselves readily to adaptation for this service. Thecontrol device as well as the operating mechanism issubstantially the same, and it is only necessary to adda semaphore to complete it. Such an installation isshown in Fig. 14, while the operating mechanism isshown in Fig. 15. The maintenance of electric switches, where there are very many to care for, will require the exclusiveservices of from one to five men. When their numberreaches a hundred or more the latter number of menwill have plenty to do as a rule, and they are providedwith an automobile for quickly reaching trouble pointsand covering a large territory. In connection withmaintenance the following description of methods forovercoming troubles during the winter season is worthquoting. It is from an article by P. Ne
