[BITList] Fwd: BBC - h2g2 - The River Don Engine - Correction

[HUGH]

As far as I can make out, from the description and from the picture, it is 3 separate single cyl engines on a common crankshaft.  The crankshaft, with 3 cranks at 120 deg, will be the only feature retained from the triple expansion configuration.  As yet, I'm not sure  how the fast reversing is achieved.

Hugh.
