Post War Locos and CW-80

Do post war locomotives slow down when the whistle is activated with the CW-80 or do they maintain their speed? I have heard that they do with other brands of modern transformers such as the MRC. I run pw with a Z-750 and there is no change in speed. Have been thinking of switching to a CW-80 as I like the retro look about it.

I have run a couple on a CW80 loop. From my experience, the 2020, 675, 2025, 2026, 2037, none of these seem to have slowed down when using the “Horn”. Again, just what I have observed. I have not used them with any lighted cars, etc., that would draw more power.
