Here is a Cheddar Samson haulings tipper wagons on Roy Wood's Holtwood light Railway. The loco has a Cheddar type whistle fitted. The Chuffer is a standard SCGP3
Here the Cheddar Samson is joined by the Cheddar Hercules to double head a fairly heavy train of mainly Accucraft and Swift sixteen stock on Roy Wood's railway.
Here is a Cheddar Hercules, fitted with a new "big bore" Chuffer running on Roy Wood's railway. This chuffer gives a slightly deeper sound in the very large chimney.
Here is Paul Hyde's brief video demonstrating the SCGP3 Chuffer fitted to his Cheddar Riesa.
