A private bus industry, dominated by owner-operators and small family businesses, was taking shape. Seeking to protect the tram system from competition, Premier Jack Lang introduced the Transport Act 1930, which empowered a new Metropolitan Transport Trust to shut down private bus routes that competed with trams, trains or other buses. The Railways were also restructured, with the tram system hived off into a new Department of Road Transport & Tramways in 1932. The Department introduced its first bus service, route 144 from St Leonards to Manly, on Christmas Day of that year. Lang's reforms established a structure for the bus network that was to endure for close to a century. On the one hand, the Department – forerunner to today's State Transit Authority – began to shut down its trams and build an extensive bus network serving the inner suburbs and Northern Beaches. On the other, the heavily regulated private operators remained small-scale, relegated to the status of feeder services for the Government's trains. But Lang's draconian Transport Act held at least one benefit for the bus companies: just as the trams were protected from them, so too were they protected from new entrants to the industry. From trams to buses Route 144 started as a service in the 1920s connecting trains, trams and ferries. But the Department's focus began to shift inexorably towards building its bus network, starting in 1937 when Kogarah's steam trams were replaced with trolleybuses. Two years later, tram services from Manly were replaced with buses. In 1948, a recommendation was handed to the Department that the entire network be replaced with buses. Though initially controversial, the move to a bus network secured broad political support and was completed between 1957 and 1961. The Department, renamed 'Government Transport' in 1952, became an operator of buses only. For much of the 20th century, land use planning in Sydney restricted development to corridors within a short distance of the existing railway lines. This discipline broke down in the 1980s, however, when the Wran Government released new areas for development far from existing rail lines. This meant that buses outside of the inner-city, government-operated network, would play an increasing role in meeting Sydney's transport needs. Lang's model divided the city into hundreds of exclusive fiefdoms and did not allow for cross-regional services. Some private operators responded with joint ventures under the "Red Arrow" brand, agreeing to jointly operate
