White Lines Bus Company was a bus operator based in Danbury CT, with a division located in Bridgeport CT. It operated local bus service alongside other competing carriers during the early 1900s (specific dates unknown). In Bridgeport, it was the predecessor to Gray Line Bus Company of Bridgeport - which likely took over its routes. Notably, it acquired the former Lordship Traction Company's bus route - once a trolley line - between Downtown Bridgeport and Lordship , a community in the southeastern tip of Stratford. Its chief competitor was Connecticut Railway And Lighting Co. (CR & L Lines), being the largest bus and trolley operator with transit routes covering the majority of the city and its suburbs of lower Easton, Fairfield, Stratford, Shelton, Derby, and Milford.
