The 1960s proved to be a decade of consolidation for the Talyllyn. Pendre works underwent several much-needed expansions, adding additional covered storage for carriages and more workshop room. Modern machine tools, along with proper lighting and a new power supply were added. Substantial improvements to Tywyn Wharf station were also made, along with continued relaying and upgrading of the track to Abergynolwyn. Passenger numbers continued to climb after the 1957 BBC broadcast; in 1960, 67,000 passenger journeys were made, increasing to 78,500 in 1964. In response to this growing popularity the railway undertook a programme of new rolling stock construction.
