Approximately 1 in 100 individuals in New Zealand are diagnosed with autism spectrum disorder (ASD), facing significant challenges in socialisation and communication. Identifying effective methods to enhance these skills is important, as difficulties can lead to adversity in independent living, employment, and relationships. Research indicates that utilising items of interest can boost social interaction motivations in autistic individuals. For example, Le Goff’s study demonstrated how structured, interest-based activities like LEGO can promote social engagement. Building on Le Goff’s (2004) findings, this study examined opportunities for facilitating social interactions and communication among autistic children through a model train club. A mixed-methods approach was applied, gathering data via observations, caregiver interviews, a volunteer focus group, and case studies. Observational data confirmed instances of social interaction and engagement with trains. Caregiver interviews revealed the club’s beneficial impact on their children and their reasons for ongoing involvement. The volunteer focus group expressed dedication to maintaining an inclusive and engaging atmosphere, emphasising the club's social value. Meanwhile, case studies showed that neurodivergent individuals participated in social interactions, joint attention, and engagement with trains within this environment. The findings indicate that the model train club is a valuable space for neurodivergent children, particularly those with milder autism, to practice and improve their social interaction skills in a supportive setting.
