I note that some of the new Vision locomotives will include the dynamo effect.

I believe it has appeared in the past.

How does this work?

Is it random or can it be triggered?

Are there accompanying sounds?

Which do you prefer, whistle steam or dynamo steam?

I'm not sure how many locos this feature has appeared on aside from the VL Challengers. On that model, the feature runs continuously from an auxiliary smoke unit. It can be turned off via a switch on top of the boiler or via CAB controls. The latest manual contains these instructions:

VISIONLINEChallenger

There is a sound of the dynamo spooling up when the engine starts but that is part of the background loco sounds and not independent of them.

Certain of the GS series VL engines will have this feature in substitution for whistle smoke because (as the catalog and related video explain), where the whistle and stack are close together the stack smoke effectively masks the whistle output. Also, as I read the catalog description these models will have smoke from all three dynamos lined up on the boiler.

Personally, I would prefer whistle smoke where the whistle is not right next to the stack but I understand the reasons given for substituting the dynamo effect.

Yes and yes.  The dynamo provided electrical power for the headlight, class lights, cab and gauge lights and tender lamps.  I guess Lionel’s thinking was, if you turn off the headlight you don’t need the dynamo.  With a steam locomotive resting, you can hear the dynamo as a annoying  whine.  When the locomotive is running, the whine becomes part of the overall noise.
