A cross- this 5x/2 miles of track was about $170,500. For the entirework, after making the credits for scrap material from theold track, the average cost per mile of completed track wasabout $27,000. DURABILITY OF TRACKIn the track consumption adopted by the United RailwaysCompany only the best materials are used, and by the use ofa concrete foundation it is hoped to obtain the most sub-stantial and durable construction possible, and one which will. l-IC. :..

After the concrete work was finished, the concrete wasallowed seven days to set before cars were allowed to runover it. This interval sufficed for the paving, so that thetrack was entirely finished before it was opened for traffic. SPEED OF CONSTRUCTIONThe United Railways Company officials are especiallyproud of the speed with which this difficult work was per-formed. For the section between Fourteenth Street and maintain the street paving in good condition. The questionis often asked how long such a track as that laid on OliveStreet will last. Of course the wear on a track is directlyproportional to the number of cars run over it. As hasalready been stated, the type of rail used in this constructionis worn out for railway purposes when the wheel flange runson the rail, which will occur when abo
