The train dispatchers know the value of the engineand they do not hesitate to rely on it to make up time ortake an unsually heavy run. As a consequence the im-provements shown by tbe indicator cards are not entirelyrealized in actual performance records. In a series ofcomparisons made by the indicator the water rate perindicator horse-power was reduced from to The indicator cards also show the cause for theslight wear on the machinery, as they are remarkaly full,the expansion lines being clear and distinc
