Document 15: Blue Bus lines (Oregon): The “Blue Bus” lines was a group of four affiliated privately owned public transportation companies that provided bus transit service in the Portland, Oregon, metropolitan area in the 1950s and 1960s. The name was unofficial but was in common use in the 1960s, and variations included "Blue Bus lines", "Blue Lines", "blue bus" lines (or companies) and "blue buses". The Blue Bus companies provided service only between Portland and suburbs outside the city, or within such suburbs, as transit service within the city of Portland was the exclusive franchise of the Portland Traction Company or, after 1956, the Rose City Transit Company (RCT). The "blue buses" were prohibited from making stops inside the city except to pick up passengers destined for points outside RCT's service area (or to drop off such passengers when inbound to Portland). The "blue" name was a reference to the paint scheme worn by most buses of the consortium. By contrast, city transit operator Rose City's buses wore a primarily red paint scheme.
