That is your only fixed voltage choice with a KW - 6 v or 20v - if you are running trains with A-U & B-U.

If the 4090 was connected to the rest of the layout using "U" to the center rail and the common "A" to outside rails, the the 4090 was providing 16v to the whistle. If you run trains with the KW only on A-U, then you can connect the whistle to "B" and set it at 16 volts(or whatever level you wish for satisfactory operation) to duplicate the 4090 setup.

Like Rob said. Or leave the 4090 hooked up to run the shed only. Or get a Z-4000! The KW is a pretty good transformer but the accessory post voltages were poorly laid out. No idea why Lionel did the KW this way.
