Railway and locomotive engineering : a practical journal of railway motive power and rolling stock . ny of the enthusiasts in theelectrical field were very sanguine intheir predictions that the relegation ofthe steam locomotive to the scrap slightly better, its subordination to go io show that the visual signalis far more reliable and trustworthythan the audible signal. An old sageput the matter tersely when he re- d, An eye can discotruth than two ears. Now with theordinary steam operation in tunnels thesmoke more or less completely inter-feres with the successful operation ofany system of visual signals; this hasbeen sadly verified only too often. No successful illumination of a tun-nel ,an be carried out in the preof smoke and steam; the unburncdcarbon in the smoke, popularly knownas soot, in the presence of moiand also in the presence of the oil thatis carried out in the exhaust, serves togive lamp bulbs an opaque coating thatrenders the source of light won!There is, however, a more serious prop-osition to deal with; all bituminous coalcontains a very considerable sulphur. N. Y. C. APPRENTICES SCHOOL MODEL OF \V. 3CHAERTS GEAR. There is one particular case in whichthe electric locomotive should by allmeans take precedence over its com-petitor, and that is in tunnel work, espe-cially where the tunnel is of four or fivemiles in length and the traffic is several instances in this country elec-tric power has taken the place of steampower for this particular class of ser-vice. It is well known that the conditionsin a tunnel of any considerable lengthare very poor in regard to the matterof ventilation, good air and light enoughto render the use of visual signals bothreliable and effective. It is true, thetorpedo is an old and trusted friend,but the use of the torpedo should berestricted to cases where, owing totemporary conditions, the visual signalcannot be used effectively.
