With big cylinders and large wheels she purrs along when notched back and makes a satisfying chuff when starting and in full gear.

A beautiful engine, and a great location, definitely a grand day out.

Nice loco, but is it really a working 3-cylinder compound, or just looking like one? I am genuinely interested.
