Now I will write a last text to "excepting valves", "separate exhaust pipes" etc.
I think I have to say that I was wrong. Yes, intercepting valves are an item that mallets have had in early times already. And with intercepting valves is strong connected separate exhaust pipes, which go directly to main exhaust pipe ore more yet to a specific exhaust nozzles. We hear while starting additional four chuffs coming from exhaust steam to the normal chuffs of LP-cylinders, if a mallet is working as an simple articulated engine . Maybe that the HP-chuffs a reduced noise because there are smaller pipes used as those from LP-cylinders, but there are eight chuffs together. My correction and my opinion, now.
Printed and to read about that theme in 1922 Locomotive Cyclopedia of American Practice.
