The video above shows what progress has been made on my kitbash of gas-electric #61 from a Bachmann doodlebug. A new can motor has been installed along with the Soundtraxx Micro Tsunami GE Cummings 70 tonner decoder, iPhone 4s speaker, and TCS KA2 Keep Alive capacitor.
The next video shows how long the KA2 keeps the sound going after the engine is lifted from the rails.
I still have a bit of detailing to do on this piece of motive power along with painting, but I am quite pleased how it's progressing. :)
