I am not an expert on holograms and hologram projections but I have thought that issues such as black smoke and fully voluminous smoke from engines could be achieved with hologram projections.
I would like input from others on this especially from those who may know alot about hologram projection.

Wow, interesting question! I'm not sure if holograms would be a good way to make smooke, etc., but you know, you could probably make them for passenger cars so they give the impression that there is a 3-D interior with people in there when there is not.
One main issue I see with it is the ability to keep the projector aimed at the stack with pinpoint accuracy while the train is moving around the layout, whether the projector was hypothetically small enough to mount on a car on the train or more conventionally at some fixed point on the layout or room. Lots of variables like lateral motion & discrete changes in speed or acceleration to factor in, can make for a pretty complex (read: expensive) system.
Transmission type could used for car/building interiors but they aren't very bright and there is a tendency for them to look ghostly. Reflected ones require a narrow viewing angle but can be spectacularly detailed.
The inside of Passenger cars and Locomotive Cabins are a place to experiment with solid state and projected holograms.

I have no doubt the idea would take much work and money to to pull off, but we might get very interesting results.

That's sort of what Marklin is working on...passengers going in and out a car....
Can see it in action at 15.30 of this Toy Fair video...very short
