Watching locomotive videos on youtube,came across an especially interesting one developed in England right after ww2 and used in boats and locomotives over there for a few decades afterward:Napier Deltic.Opposed piston two stroke diesel,18 pistons operating in double ended cylinder bores arranged in a triangle shape with a crankshaft at the 3 "points"of the triangle,the 3 crankshafts geared to the output shaft.Quite a few have been preserved in running order so the cool,unique sound can still be heard
