Railway and locomotive engineering : a practical journal of railway motive power and rolling stock . relatively high or low maintenance cost, andthe method of shopping power is one of the primaryfeatures to be considered, and it may be said that thepolicy used in the matter of shopping power becomes acentral factor, and may be considered as the hub of theforce at play. There are two extremes of policy in the many variations between them. One is what may betermed the high-frequency-shopping and the other thelow-freqtiency-shopping policy. The high-frequency-shopping policy is that based on running locomotivesthrough shops with an anticipated service of from twelveto fourteen months with a minimum of roundhouse at-tention. The low-frequency-shopping policy is that basedon running locomotives through shops with the ideaof having a service of 24 months or more and with agreater degree of roundhouse attention to attain thislength of service. \ital elements in determining such apolicy are the relation of the number and size of locomo-tives owned to the business handled, the road conditions. Fig. 1—Data of Steam Locomotive Repairs Showing Results ofChanging from a High to a Low Frequency Shopping Program for hauling heavy- or light-tonnage trains, the topographyof the country traversed, the distribution of industrialcenters, the presence of large terminals, the spacing andcapacity of roundhouses, the distribution and assignmentof fKDwer, the placement of forces as between roundhousesand back shops, the rapidity with which mileage is run out,and particularly the roundhouse and back-shop facilitiesfor handling certain classes of work. Furthermore, wherea railroad has back shops of an obsolete character it ispractically as well oiT doing its work in roundhouses, andit may be found helpful under such conditions to constructsmall modern back-shop facilities at critical points to carefor division requirements without increase in overheadexpense.
