I had the Boston Albany version. Lionel switched the motor back into the firebox and it was a large Canon motor.
The smoke fan had gotten noisy so I lubed it and it corrected the problem. These actually had a plastic smoke unit bowl which I though was strange.
Smoke output was good. No whistle steam offered on these. In fact , there was no whistle detail on the B&A version at all. It was also missing on the K Line version as well.
It was a good puller and smooth runner. 
Heres really poor old video with the smoke unit on low:
