Class P—Renewal or resetting of a majority of tubes and general repairs. Fig. 3 to the machinery and tender. This class to include cases where boilers orfireboxes are repaired, but no entire new sheets Class E—Where locomotives have tires turned or partial renewal of tubesor both together with light repairs to machinery and tender. Class E-F—Repairs to the machinery and tender similar to Class Erepairs made necessary on account of breakage or failure of some importantpart of the lueomotive not due to accident or collision, where tires maynot need turning or tubes require partial renewing. Class F—Slight repairs to the machinery and tender. Accident repairs are classified under the letter indicatingthe approximate cost corresponding with the necessary re-pairs given the locomotive. The report of such accident re-pairs shows the classification letter assigned on the abovebasis with the prefix Ace. It is impossible to give the costs of the various repairs asclassified above, due to the fact that the classificatio
