should be provided at this point. The location of this facility contemplates a separate attendant and if possible the track should be elevated over the bins. For terminals serving under one hundred engines, the sand handling plant may be combined with coaling station so one man could attend both. From the coaling station two tracks lead to the turntable and the engine house with a branch from one passing around the table. A slip switch and crossover at this point permits an engine to move to the outbound terminal tracks without passing over the turntable. A stub-end cinder car track with capacity for ten cars is shown beside the cinder pits, and it is arranged so that loads or empties may be switched from or to the run-around tracks. Outbound Trackage After power has been turned, it may be placed in the engine storage yards which are reached by two tracks leading from the turntable. One track passes beneath the coaling station and the other beside it so that power may be coaled outbound. Three tracks lead from the turntable in the opposite direction; one is intended for inbound movements and the other two for outbound power and storage at the house end of the terminal. Engine Storage Yards Two separate engine storage yards, one for each engine house, having capacity for at least 20 engines each are indicated on each side of the terminal. Each track holds six locomotives thus reducing switching at this point to a reasonable minimum in order to put any stored engine in service. Water Facilities Water columns at points of arrival and departure of power are arranged so that an engine taking water will not block the movement of another. Engines entering the terminal and urgently needing water may obtain it at water columns located near the entrances to the terminal yard. Ordinarily water will be taken at the columns in advance of wash platform or on the outbound tracks. Outbound engines may obtain a full tank of water at the column at the outlet to the engine storage yards. If, on leaving the engine house, there is a prompt need for water, the column between the two outbound tracks and 300 ft. from the table, serves that purpose. Water for power, entering or leaving the terminal by way of the right end, is provided by columns near the turntable and at the lead from the main track. In connection with the water supply, it is contemplated that the pump will be located in the power house and the two tanks at two points on each end of the system. Tank storage for about twenty-four hours' supply to carry through in case of break down should be provided. Observation has been that at the average terminal, the reserve water storage is usually too small. Turntable Track approaches to the turntable should include at least two from the terminal yard side and two which can be used to approach and leave the table from the side away from the yard. At a busy terminal two approach tracks and two tracks leaving the table, making four in all, are recommended. It is also desirable from an operating standpoint to have all approach tracks line up with those leading into the house. While the size of the turntable is a matter for the consideration of another committee, it has a material bearing on the number of stalls possible in a house without requiring frogs in the track at the edge of the table. Generally speaking, the longer the table, the less waste floor space at the rear of the house. This is true because it is possible to reduce the stall angle. Engine House The engine house has been located at a sufficient distance from the terminal yard runaround track to permit straight track leads from the coaling station to the light repair shed which may be considered as a means of future expansion. The first section to be constructed is also placed so that the circle may be completed or a second house and table provided as a future development. Your Committee has found quite a divergence of opinion on the location of the engine house proper and believes that it will be out of the question to reconcile this. On some roads, particularly those in the West, where they have long divisions, it is necessary to place every locomotive in the engine house before restoring them to service. One stall to two or three locomotives for a twenty-four-hour period is all that is required, consequently a full circle house may be operated over one table. In the congested district your Committee finds that preferably thirty and not to exceed forty stalls should be operated over one table, and particularly at terminals where four or five locomotives per stall are handled in a twenty-four-hour period. From the foregoing it will be seen that in the case of one terminal, provision will have to be made for completing the full circle, whereas, at the other, provision need not be made for more than forty stalls to the circle. In either case, your Committee would recommend track approaches from opposite sides of the table and approaches so arranged that one track will line across the turntable with one in the house. This will permit a dead locomotive to be placed in the house without difficulty. Preferably this track should be one that leads through the engine house into the machine shop. The type of engine house, engine house equipment and recommended construction are being handled by another committee. When the terminal is expanded 100 per cent, your Committee believes that the second table and engine house located as shown will best meet operating conditions. Then, too, if conditions like those mentioned as prevailing on Western roads occur the full circle engine house may be developed without difficulty. In case two tables are installed, a section of track with crossing frogs connecting the tables will be found useful. Machine Shop The machine shop is considered both as an independent working unit as well as an essential part of the engine house proper. Wheeling and unwheeling and other repair work requiring the attention of skilled workmen might properly be handled in the machine shop. In any event the drop pits should be near the entrance to the machine shop. In the typical layout, this shop is connected to the engine house on the terminal approach side by a passageway lower than the machine shop building proper, but high enough to clear a locomotive. The purpose of this is to prevent engine house gases entering the machine shop and still have an open passageway between the two. The tool room opening off of this passageway makes it convenient to both the engine house and machine shop. The foreman's office is also shown on the passageway and near the engine lead and departure tracks where he can observe movements at the turntable and at the same time be convenient to the engine house and machine shop. A small blacksmith shop is shown in the corner of the machine shop close to the engine house so that it may serve both. As an alternate, another satisfactory machine shop layout is shown. This, it will be noted, occupies a part of the engine house circle and puts the drop pits in the machine shop proper. Light Repair Shed While the light repair or tightening and test shed has been employed by a number of roads for many years and has demonstrated its economy, it is not in general use throughout the country. Your Committee believes that it is to be recommended at terminals turning one hundred or more locomotives. It provides cheap floor space for tightening and testing, thus reserving the higher priced floor space in the engine house proper for heavier running repairs. It has been found. that at some terminals, as many as sixty per cent of the locomotives handled never have occasion to go into the engine house. This shed may be of reinforced concrete or heavy timber construction. It should preferably be located near the machine shop where parts are available and supervision made easy. Store House The store house has been placed so that it is convenient to the engine house and machine shop, where the call for supplies will be greatest. A liberal outside platform with ramps leading to the engine house and yard and a track on which material may be delivered in carloads covers the essential requirements. Permanent walks and drives between the various facilities and the store house are very essential to economical handling of materials. A scrap platform on the store house track, but near the points where scrap accumulates, is also shown. The through wheel track contemplates the delivery of good wheels and storage space for bad orders. |
