Got mine yesterday… what a wonderful thing, TMCC operation, Horn, bell, engine sounds, coupler clank, air dryer popping, and a Beep-Beep sound when you press for crewtalk.
You can set the sound levels of the horn/bell form the engine sound, cool little bugger
What he’s talking about is a TMCC/ Sound upgrade from www.electricrr.com. I ordered two of their Beep TMCC/Sound upgrade kits yesterday. They make great stuff…easy solderless installation on the Beep upgrades I believe.
They did have some Beeps w/ TMCC/Sound installed for sale, but I’ m not sure if they have any left.
Got the email from them the other day. Plan on upgrading my two NS Beeps as soon as I allocate the extra $$$$. Will also do some GP7/9’s I have. It will work in them too.
