In series C, showing three cards taken at three-minute intervals, the speed rose from 48 to 70 miles per last card was taken at 11%-in. cut-off and at 70 miles perhour. This power was sustained about 10 minutes, but the{reman believed that he could have kept it up for the entire trip without exceeding his own capacity or that of the train weighed about 350 tons and made the 10 stops al-ready r
