Historical information
Details the numbers of tram defects by type due to a variety of causes by depots. Allows for analysis of the reasons and possible solutions. Note the numbers for "soiled" trams - probably someone was sick on the tram (drunk), and collisions - not just minor scrapes. Gives the mileages per defect and overall miles per defect. Signed Ken Hall, Works Manager.
