Is it possible to control the cylinder smoke independently of the chimney smoke?
It would appear not as the "cylinder smoke" feature, where available, consists of a pair of flexible tubes leading from the smoke units exhaust.
I'm fairly sure that, on real steam locos, the cylinder cocks are only opened if there's a chance of water in the cylinders, e.g. on starting from rest with cold cylinders. The steam could condense and, in the extreme case, the resultant the water cause enough pressure to crack the cylinder casting. Even if I'm mistaken it's very rare to see a train running any distance with the cocks open.
I suspect that the only way I could run a loco fitted with one of the latest smoke units with smoke from the chimney only is to plug the relevant smoke unit holes.
