The controlling mech anism 49 is arranged in the cab 4|. The element 2 includes a steam boiler 52a, a 65 ñrebox 5.3a and an ash pit 54a.- The boiler 52%L is provided with a steam dome 55a.. The ash pit 54a will be closed at its sides and bottom so as to not interfere with forced draft through the line I9. The ash pit willbe accessible through a door 8lb 70 (Figure. l) at its front. for ,ñfteen pounds of pressure. The valves 13a, 'I3b and '|3C have connected thereto actuating means 13d therefor operated from within the cab 45 4|.

The forward open end of _the portion 84 is controlled by a normally closed hinged Valve _8_6, which is shifted tol open position by the means 81 for the purpose o_f supplying air when the locomotive is not in motion. The means y The element 3 includes a housing or hollow 81 extendsl up. through floor 42 and is operated structure 56 having its bottom arranged above the lower ends of its sides. The housing 56 is from within the cab 4|. Extending within the portion 84 of section 82 is a shiftable damper lilla for the rear end of said portion 84 and which is supported inv a manner similar to the manner in 75. which the structure 38 is supported, that is to say, operatedby the door V87hl of the ?lrebox.v The 7.5 3 2,122,341 damper 87a is so connected with the door 8lb to provide for the damper being closed when the door is open and opened when the door is closed. The line I9 is provided for creating a draft of preheated air when the locomotive is in motion for entrance into the ñrebox through the grates for the purpose of increasing combustion. The air entering line I9 is heated as it passes through the condenser l'l and conducted for discharge 10 into the ash pit for passage therefrom into the ñrebox. Leading from the water tank 6, extend ing through the cover 4 into the element 2 and opening into one side of the hot well 19 is a sec tional water supply line 88. Arranged within the 15 element 2 is a water feed line 89 which extends from the other side of the hot well '19 and opens into the water space of the boiler 52a. The line 89 has interposed therein a feed water pump 90. The element 2 is provided with a smoke discharge 20 flue 9| leading from the ñrebox of the boiler. Interposed in the line T5 is an oil separator 92. The line 'i6 is for supplying steam to the tur bine at full boiler pressure when the locomotive is running slow and under a heavy load. The 25 valves 13a, 13b of line 13 and the relief valve 13c are to be employed when the turbine is using steam at boiler pressure. The purpose of valve 'I3a and by-pass 'I3e is to allow the exhaust steam from the engines to escape when the turbine is 30 working under high pressure. The valve 13b keeps the high pressure steam from escaping be fore entering the turbine. The relief valve 'l3c keeps the back pressure on the reciprocating en gines from increasing when working with the tur 35 bine. There may be obtained, from within the cab, a clear View of the track on both sides by the en gineer or ñreman. . The condenser is located at the front of the 40 train as this is the coolest and most exposed place for obvious reasons and is inclined to prevent air resistance. The turbine and electric gener ators are not placed here as there are no inde pendent drive wheels for the forward section. 45 The water tank, boiler and coal are of course 1o cated near together, and the forward motion of the train adds to the draft in the ñrebox. The engineer and fireman are located in the front of the second section as the extreme front might be the point of greatest danger, but this position brings the fireman adjacent the ñrebox and coal supply, and also gives a forward unobstructed View. The air inlet located above the condenser is at the hottest point of the latter and feeds to the ñrebox. What I claim is: 1. A streamlined locomotive including steam 10 generating means and a driving engine, connect ing means to conduct the steam exhausted from said engine to a secondary steam engine, connec tions for the exhaust therefrom to a condenser, said condenser forming a portion of the front 15 of the locomotive and being upstanding and rear wardly inclined, an air intake line extending through the upper portion of the condenser, an air deflector overhanging said intake line and adapted to pick up air deiiected upwardly from 20 the condenser of the locomotive. 2. A streamlined locomotive having an air de flecting pilot, a grille thereabove and a condenser immediately back of the grille and at the front of the locomotive and forming a continuous surface 25 for de?lecting air upwardly, said pilot, grille and condenser being upstanding and rearwardly in clined and forming the front of the locomotive, means to conduct exhaust steam to the condenser, an air intake line extending through the upper 30 portion of the condenser, an air deflector project ing forwardly from the top of the intake line and adapted to direct air deflected upwardly by said pilot and condenser into said line. 3. In a locomotive including steam cylinders 35 and their connections and driving wheels, a pilot in front thereof and a grille above said.pilot, forming an extension thereof and both inclined rearwardly from the bottom to the top at an upwardly slanting angle, a condenser inclined im 40 mediately back of said grille and extending from immediately above the pilot to the top of the 1o comotive, an air inlet pipe extending through the top of the condenser and its upper portion ex tending forwardly to form means for deflecting 45 air into said pipe.
