It will be apparent that this progressive system of over-hauling is a great step toward higher reliability and de-creased cost. A car unfortunately cannot be designed likethe wonderful one-hoss shay, with equal strength inevery part. Superior as the regular mileage system is tothe policy of time maintenance in placing the car units onan even basis, it cannot be denied that it has an inherentimperfection in the assumption that apparatus so dissimilaras control contactors and motors, for instance, requireoverhauling at the same mileage. On a small railway, ofcourse, it might be undesirable to introduce so refined a.
