There is no steam chest effect on this engine. Legacy engines (non visionline) have either whistle smoke or steam chest smoke but never both as of today.
Previous runs of this engine suggest that the whistle comes off to fill the whistle steam smoke unit. I'm not sure if they have changed this but your manual seems to indicate that it was changed. I looked for a parts list and it's not available. This maybe a question directly for Lionel.
Just for reference from the Lindberg version manual...
Pull the whistle off the boiler to add smoke fluid for the whistle steam effect. Use the small funnel to
add the smoke fluid to the hole. For the first filling, we recommend using 20 drops of smoke fluid. From
then on, 10 to 20 drops will be sufficient.
Again they may have changed this from the previous versions based on your manual. Seems odd though to me they'd re-engineer it.
