The first Red Ball Express train with high priority cargo left Yokohama at 1330 23 July. Regular daily runs became effective two days later. The schedule called for the Red Ball to depart Yokohama at 2330 nightly and arrive at Sasebo at 0542 the second morning thereafter, and for the cargo to be transferred directly from train to ship.
Ship departure was scheduled for 1330 daily and arrival at Pusan at 0400 the next morning. [15-46]
Army transportation men worked almost ceaselessly during July to bring order out of near chaos in the train movements from Pusan toward the rail-heads at the front.
