Travelling daily on the Talyllyn Railway – the railway that inspired the Rev Awdry's Thomas the Tank Engine stories – must have made an impression on the children attending Abergynolwyn school, seen here leaving the station and assembling in the playground for the camera. Engines and stations are seen as the train journeys along, no longer carrying slates from the Bryn Eglwys quarry where, amongst the grey ruins and spoil heaps, a young man appears like an exotic butterfly.
