I have a Lionel PRR 2-10-4 J1-A #6-28078. It produces very little smoke. The engine has to be almost standing still to see the smoke. It’s a TMCC engine. Lionel’s description of the loco says it has a puffing smoke unit. Does this mean that it has a plunger type smoke unit or does it have a fan type? This would help me out in trying to increase the smoke output. 
Thanks for any advice.

A Lionel 8057-200 smoke unit modified with an 18 or 20 ohm heater and enlarged air intake will make great smoke. I see no reason why that smoke unit would not fit in that boiler. You will also need a Super Chuffer board to pulse the fan and make puffing smoke.

i have not worked on that particular engine but you may be able to modify the smoke cam lever (since the plunger puffer will be gone) and retain the cherry switch actuator so as to produce the necessary pulses for chuff and puff. If not, you will also need a Chuff Generator board to replace the cherrry switch function. Not to be negative but K-Line scale Hudsons and Mikados used the same style cam lever actuator, and its basically impossible to retain the original cherry switch operation. The CG also allows selection of correct 4 chuffs per rev instead of only 2 chuffs.

On the plus side, once modified you will have a great smoking and puffing engine with rule 17 lighting, and cab lighting that extinguishes when the engine is in motion. It would be a great mod!

Actually mounting the smoke unit in a steamer boiler is one of the easier tasks IMO. It generally fits up against the smoke nipple on the boiler stack nicely, and clears the inside of the shell with 1 or 2 mm each side. I use thin wood wedges to gently jam/lodge it in place; no muss, no fuss. I find cedar shake shingles work nicely, it only takes a couple of very small pieces, about 1 inch square. See the yellow arrows below. Never had one come loose yet.

This particular example is an MTH PS-2 smoke unit in a converted K-Line scale Hudson, but Lionels 8057-200 is dimensionally similar, and I have mounted several of them this same way.
