Can a sound decoder be added to a Bachmann SD40 DCC equipped engine? If so what brands of sound decoders will work?
Thanks!
https://tcsdcc.com/installation/ho-scale/1853 TCS decoders are very nice.
What are called resistors are 4.7 microhenry ferrite inductors. Zero resistance. All Bachmann DCC locos come with them. Some are wire wound. I measured them on my locos with an inductance meter. Many confuse them.

I should have remembered SoundTraxx. You could substitute their parts. I am assuming you have experience.
