How come this loco has four valve gears instead of two? I know the first one next to the cylinders is for the drive pistons. -Hovertrain

RE: Valve gear

Could possibly be for a third cylinder. Looks as if the cylinders are slightly at an angle and raised for a possible center main driving rod. Would need more info to really know for certain.Mykel

RE: Valve gear

I agree, looks like the second valve gear associated wih a three -cylinder locomotive. The third cylinder was probably in the center, slightly inclined above center line.

RE: Valve gear

and it is only on machines left side. Similar usage can be seen on German past WWII Machines BR10. In that case for 3HP Cylinders without compound connection.Roman

Hi,Jonathan, I can imagine that. It was my first thought when i saw that picture of a 242, Oh that's a four cylinder. But after I found those pages, it turned out to be wrong in this particular case.Dick van den HovenValve gear – image 75

RE: Valve gear

Hi AllNice to see so much interset in a French machine.Definitly 3 cylinder compound, built in 1946, capable of about 4500hp at the tender draw bar and only weighing in at 21T axle loading.A true masterpiece of design.Viva Capelon
