Steam Locomotive Information

Here is the photo album for Penrhyn Slate Quarries No. 'George Henry', a 0-4-0VBT located in Tywyn, Gwynedd. If you would like to suggest additional photos for this album, please click here.

The boiler of this typical De Winton product with the regulator, centre, and the reverser to the right. The boiler pressure gauge is to the left hand side.

This unusual view, looking down on the loco shows the layout of the machine well. Ahead of the boiler on the right of the photo are the two vertically mounted cylinders with the main steam pipe from the regulator valve (on the left of the photo) at the bottom.

These are the vertical cylinders, bolted to the boiler with their valves side by side between them.

Sandwiched between the throws of the crank axle are the eccentrics and these are the eccentric rods for the two cylinders.

The safety valves are attached to the side of the boiler.
