In 1960 there were two regular 'slow mixed' trains on the TAR between Port Augusta and Parkeston, one, the 'Tea and Sugar' ran westbound and the other the 'Bomber' eastbound.
At that time (1960) both trains left their respective origins early on Thursday morning. The Tea and Sugar stabled enroute at Pimba, Barton, Cook (2 nights), Loongana and Zanthus, arriving Parkeston around 1200 on Wednesday. The Bomber stabled at Zanthus, Loongana, Cook and Tarcoola arriving at Port Augusta late Monday night.
In more recent years the Tea and Sugar was train 521 and the Bomber was 480 having been advanced to a late Wednesday departure. The Tea and Sugar shunted Woomera during its lengthy stopover but the bomber had only a couple of hours at Pimba on Monday afternoon. IIRC almost all Woomera traffic came from the east.
In 1960 there was a Budd railcar from Port Pirie Junction which arrived Woomera at about 0001 Monday morning. Other services arrived Wednesday evening and on Friday evening. The combination of the Friday and Sunday services allowed a weekend of sorts in Adelaide (Whacko!!!).
