The post war ZW I have will work the newer True Blast 2 horn units by Williams.
A Lionel CW-80 may not work with True Blast 2, as it don't work well with MTH engines, don't matter what series of CW-80.
If you can't get a sound activation button, you can buy an MTH Z-750 or Z-1000 and that should give you both horn & bell features. However you can only access one sound feature at a time with the True Blast 2 units.
