208 THK DIRECT-CURRENT MOTOR CH. IX 



When the stops are frequent it becomes worth while 

 to consider the saving of time effected by taking a large 

 current at the start; but in suburban traffic this con- 

 sideration would be of small importance. On the other 

 hand, we must remember that it is mainly the peaks in 

 the current curves for individual cars that are responsible 

 for the irregular load at the power house, and that the 

 advantages of a steady demand will probably outweigh 

 any gain that might result from a small saving in the time 

 of starting.
