The catalyst proved to be the wholesale scrapping of steam traction which began in the mid 1950s and continued until 1971 when the last JA class locomotives were withdrawn from the Main South Line.
At that time, there was a nationwide move to save railway equipment which resulted in the large-scale purchase of locomotives and rolling stock and the establishment of the major preservation sites in New Zealand.
It also held monthly members' meetings, often on railway premises, and organised special conventions and festivals.
Passenger shuttle services and excursions operated daily throughout the week of this festival, which was attended by locomotives, rolling stock and railfans from all around the country.
Changes in employment law and working patterns for most New Zealand citizens resulted also in a major reduction in voluntary resources for groups all around the country.
