Exhibit "A" Cost of Cleaning Fires and Loading Ashes Into Cars-Continued ENGINE HOUSE AND POWER PLANTS AND SHOP EXTENSION, COLLABORATING WITH DIVISION V MECHANICAL Engine Houses GEO. W. BURPEE, Chairman; L. P. KIMBALL, Sub-Committee. Your Committee on Construction of Engine Houses, as one of its items under Subject (3), was appointed on October 2, 1920, with instructions to study and report on the Construction of Engine Houses in cooperation with a Committee of Division V-Mechanical, of the American Railway Association, which has had the same subject under consideration. On December 15, 1920, the full membership of the Sub-Committee met at the American Railway Association offices in Chicago with the corresponding Committee of the Mechanical Division of the A. R. A., to discuss the subject matter of the Final Report of the latter Committee. The conclusions reached at this meeting, as a result of information obtained by the Mechanical Division, together with information subsequently secured from this Sub-Committee's Questionnaire, form the basis of the report presented herewith. On the 27th of January, 1921, a Questionnaire covering the principal features of the Design and Construction of Engine Houses was submitted to approximately fifty members of the Association to elicit information relating more particularly to present tendencies in design as exemplified in the most modern houses. Replies were received from the representatives of forty-two different railroads, covering all sections of the United States and Canada, and embracing all varieties of climate. The Committee wishes to express its appreciation of the promptness and thoroughness with which the information was furnished. Following is the Questionnaire: (1) Please submit two prints each of plans and sections of what you consider the best round houses on your road. In cases where you have modern round houses with wood frame, reinforced concrete or steel frame, it is suggested that you submit prints of each. The prints should show length of turntable, distance from edge of turntable to inner edge of house, width of stall at inner edge, track angle or number of stalls in the full circle, all dimensions of the house proper such as clear height at door, height at rear side, clearance at doors, etc., and length, width, depth, wall thickness, etc., of engine pits. (2) For what class or classes of power is this round house or round houses to which you refer used? (3) How many engines are cared for in the round house per day? How many during the busy period? What is the duration of the busy period? (4) What type of floors have you found most satisfactory in a round house? Upon how many years' service of the type of floor in question is your opinion based? Have you found any type of floor particularly unsatisfactory? (5) What type of roof have you found most satisfactory? Upon how many years' service of the type of roof in question is your opinion based? Have you found any particular types of roof unsatisfactory? It is understood that the roof here refers to the roof proper, such as wood, reinforced concrete, combination reinforced concrete and hollow tile, gypsum block, etc., and not to the waterproofing. (6) What type of doors and windows do you consider most satisfactory, i. e., swinging, folding, rolling lift doors, wood or steel sash, etc.? (7) What type of lighting have you used; general illumination by flood lights, individual lights widely distributed, or a combination, and what degree of intensity of light have you found most satisfactory? (8) What degree of heat have you found to be satisfactory in the round house during ordinary cold weather and what type of heating system do you consider most efficient? (9) If direct radiation, what location do you consider most effective for radiators or coils? (10) If indirect radiation, is air drawn from outside or re-circulated? How many changes of air per hour? Are ducts located underground or overhead? If underground, at inner or outer edge of round house? What do you consider the most effective location for the outlets, at the posts or in the pits? (11) With what type of smoke jack have you had most success? What is the length parallel to track? Size of outlet through roof? (12) Where your round houses are provided with traveling cranes what is the capacity of such cranes? Where jib cranes are used please show their location and capacity. Do you use tractors to handle parts from the jib cranes? Where monorails are used, please show location and capacity. What is your opinion in regard to relative effectiveness of these various devices for handling the heavier parts of the locomotives? (13) How many drop pits are provided? Please submit prints showing details of the drop pit. (14) Are your round houses equipped with unwheeling hoists, and, if so, have you found the unwheeling hoist economical for this purpose in comparison with the drop pit? (15) In the case of round houses where no back shop is provided, what space and what tools do you provide for machine shop work for maintaining running repairs? (16) To what legal requirements are you obligated to conform which affect side clearances, overhead clearances, sanitary facilities, heating or other features? (17) Have you any special agreements with the workman affecting in any way the design of the round house or the facilities provided? Replies were received from representatives of these railroads: Atchison, Topeka & Santa Fe Railway. Boston and Maine Railroad. Canadian Pacific Railway. Central of Georgia Railroad. Central Railroad of New Jersey. Chesapeake & Ohio Railroad. Chicago & Western Indiana Railroad. Chicago & Northwestern Railway. Chicago, Milwaukee & St. Paul Railway. Delaware & Hudson Company. Delaware, Lackawanna & Western Railroad. Denver & Rio Grande Railway. Duluth, Missabe & Northern Railroad. Elgin, Joliet & Eastern Railway. El Paso & Southwestern System. Grand Trunk Railway. Illinois Central Railroad. Lake Erie & Western Railroad. Louisville & Nashville Railroad. Michigan Central Railroad. Minneapolis, St. Paul & Sault Ste. Marie Railway. Missouri, Kansas & Texas Railway. Nashville, Chattanooga & St. Louis Railway. Toledo & Ohio Central Railroad (New York Central Lines). New York Central Railroad. New York, New Haven & Hartford Railroad. Norfolk & Western Railway. Pennsylvania System. Pere Marquette Railroad. Philadelphia & Reading Railway. Pittsburgh & Lake Erie Railroad. St. Louis-San Francisco Railway. Union Pacific Railroad. The information obtained has been classified and tabulated and is presented in the following exhibits: (C)-Diagrams of engine house cross-sections. (D)-Tabulation of General Dimensions and Descriptions. Previous Reports to the Association on Design of Engine Houses The subject of the design and construction of Engine Houses has been considered at several periods in the past by the Committee on Buildings and your Committee has carefully studied all previous reports with the idea of bringing up to date the information contained in past "Proceedings." The first treatment of this subject is found in Volume 6, 1905, and the only subsequent reports in Volumes 7, 9 and 10, 1906, 1908 and 1909, respectively. The subject matter in the current edition of the Manual is based on these previous investigations. Therefore the desirability seems evident of presenting to the Association such information as will show the changes in engine house design during the last twelve years. Your Committee does not feel that the development of a standard engine house adapted to all conditions on all roads is practicable, but that each situation must be analyzed and such a house constructed as will satisfy most economically the special requirements. It has endeavored, however, to set forth the general considerations of design and layout and to present in a convenient form such information as to the various types, details of design, and materials of construction, as will be of use to members of the Association. |
