Hi Jerry,
I assume this is the loco you are referring to:
This is a model of a Mogul design old-timer steam locomotive. It has a Coca-Cola® paint scheme in Era III. All of the driving wheels are driven by a power

Regarding running this in DC analog, the manual says the following:
Analog Operation
This decoder can also be operated on analog layouts or areas of track that are analog. The decoder recognizes alternating current (DC) and automatically adapts to the analog track voltage. All functions that were set under mfx or DCC for analog operation are active (see Digital Operation).
Looking at the default CV setting it looks like F0 (lights) and F6 (operating sounds) are active in DC analog mode.
You should be able to change the volume of the operating sounds with the manual volume control, and trigger the bell and whistle with track magnets, but all the other weird and wonderful sounds would require you to use DCC (or mfx).
There is also note about the synchronised smoke unit:
Smoke Unit
In analog operation, the smoke generator synchronized to the wheels is turned off due to its power draw. This can be turned on by setting CV 13 from Value 32 to Value 96, but this may affect the running characteristics when running very slowly – depending on the current supply.
If you want that on you will need to ask a friend with DCC or your dealer to set the CV in question which will effectively turn F7 (smoke generator) on in DC analog mode.
Hope this helps.
