I've lost the original thread stating that a Airfix Class 31 hauled
105 coaches.According to my 1988 Dapol catalog, it was a Dapol ex Airfix Class 31 that holds this record. Also, a Prairie Tank loco pulled 60 "B" coaches. No mention of the date or location, just that the above record was carried out at a public demonstration, and both locos where selected at random.
