The EZ-Command absolutely can support sound locomotives, there are only two caveats.
1. You can only use functions 0-9, which are where most of the sound commands
2. You can't program CVs to customize the sound profile.
If you can live with those constraints you should be fine depending on how many locomotives you want to operate at a time.
