The Golden Age of Steam

The 'Sir William Prescott' triple expansion steam engine at Kempton.
Named after the then chairman of the Metropolitan Water Board, along with its companion engine, the 'Lady Bessie' (named after Sir William's wife), behind me as I took this shot, the Sir William supplied 19 million gallons of drinking water a day to North London between 1927 & 1980.
Restored to working order by volunteers it's now the largest operational engine of its kind in the world.
Perhaps more importantly, the cafe was great value. Two cups of tea, an apple juice, two large slices of homemade Victoria sponge & a cupcake: £6.10!
And we got a ride on a steam train.
