I know the latest 0-4-0 Porter has mechanical chuff triggers on the axles. I don't know about the 2-4-2, but I'd think it would given both locos got similar drive upgrades when they were re-released.
Having said that, depending which DCC decoder you use, you may or may not have the option of using a chuff cam. The latest decoders from Soundtraxx (Econami and Tsunami2) rely on BEMF calibration to control the chuff rate. It's pretty darned accurate, too--much better than older generations of that technology.
