150 Straight Track is a Trains set released in 1966. This set was in production from 1966 until 1976. From 1966-72 this set was sold in all countries. But from 1973–76, it was only sold in continental Europe, Britain, Australia and Canada. During the production run, this set underwent several box style changes. From 1966-72 this set contained 16 blue straight rails and 9 white 2x8 cross ties. In 1973 this set was remodeled and it contained 18 blue straight rails and 10 2x8 cross ties. Earlier packs contained white 2x8 plates made of the earlier (1955–62) plastic mix that was used for regular large plates. Later packs contained ABS 2x8 white plates. This set was replaced by 156 Straight Rails with Sleepers in 1976.
