Sam:
As requested I tested the tender by itself and got no sounds at all. I tested it in 4 different configurations: in Conventional Mode using a postwar ZW with the switch on the bottom of the tender in the “Rail sounds” position first and then in the “Signal sounds” position, second. Then I repeated those tests in the TMCC Command mode using a CAB-1. In addition the coupler did not open in command mode when the rear coupler key was pressed on the CAB-1. And just to be sure it was OK, before these tests without the engine, I ran it with the engine in command mode and the sounds and coupler worked perfectly.
I’m sure it’s a different tender than yours. As indicated previously this tender came with the command- controlled traditional sized K-4 engine catalog #6-38089 (cab #3678) in 2004.
HTH,
Bill
