Stack Hood for TunnelIn our issue for November we illus-trated a smoke conduit used on the SantaFe type locomotives of the Southern the Cincinnati, New Orleans and TexasPacific Division between Danville, Ky.,and Chattanooga, Tenn. As then ex-plained this conduit was found to benecessary because of the large sectionalarea of those locomotives, which nearlyfilled the tunnel clearances. On the smaller locomotives of the mi-kado (2-8-2) type a hood like that shownin the accompanying engraving is usedvery successfully. When running in the. LOCOMOTIVE WITH HOODFOR TUNNEL. open the hood, which is of cast iron, oc-cupies the position shown in the engrav-ing. But, when passing through tunnels,it is thrown forward by an air cylinderand an operating mechanism so that itrests on the front edge of the stack andserves as a deflector to throw the escap-ing gasses back along the line of the boilerand project them over the top of thecab. They are thus prevented from strik-ing against the roof of the tunnel andbeing thrown back downward and intothe cab. While this arrangement does not freethe cab from smoke, like the conduit,it does serve to relieve the situation andmake the cab more endurable than itwould, otherwise, be. Air Brakes for SwedenAs was mentioned in a former report,the Swedish private railroads have beenreluctant to adopt air brakes, but it isprobable that sooner or later they willfollow in the footsteps of th
