To actually ANSWER the question

if your loco is a 0-6-0 , 2-6-0 or 2-6-2 with a smoke unit it should be a simple matter of take old unit out then insert the new smoke unit.

Here is an explosion chart of  0-6-0,2-6-0, 2-6-2 the only difference being the lead and trail trucks.

I will not waste my time in any debate about the pros and cons or opinions of smoke.

Your layout, you run it the way YOU like.

i have this set, loco does not smoke

2-4-2 are interesting and different

basically what jbrock posted already.

If you got the room a figure 8 track is good idea as well

for some reason I cant seem to view the 2015, yes I got the latest and greatest java and adobe flash player.

Has anyone purchased the latest version of this loco and what are your opinions of it?
Thank you very much for your time and assistance.

I own one.
The 1st thing I noticed about it is the weight, this is Heavy for a model loco its size.
Seems to be a good puller.
Good runner too so far no complaints.
Details are good enough to please my eye.
Would I buy another ?   Yes.

I have installed HH on modern locos,,,no problems,,,sorry naysayers 

and then Again,,,,
If you have a large fleet of horn hook rolling stock, it would be more cost effective to just install horn-hook couplers on a new loco or two.
If you enjoy casual continuous running the horn-hooks still work well for that.
If you are into serious switching operations, knuckles are the way to go.


Conversion Cars, already mentioned in earlier posts work well too.

This is sort of close, great little forum.
Good peeps to be found there,,some are even members here.
