DCC Impulses Column - 6
consist has BEMF enabled and runs smoothly. The one that
does not have BEMF enabled has three identical era Stewart F
unit models but the engines have different-vintage decoders
with different BEMF designs. Disabling BEMF for the group was
finally my choice to achieve the desired performance without
changing decoders. If I were to put TCS A4 decoders in all locos,
they would run fine with BEMF enabled. The same holds true
if I were to put a SoundTraxx Tsunami in one loco and “Tsilent
Tsunami” (motor and lights only) decoders in the others.
Let’s look at the majority of the club consists that run flawlessly
with BEMF enabled. Within each consist:
They have the same manufacturer, vintage, and model locos.
For example: Life-Like Proto 2000 GP20 models from a light
blue box.
They have the same model and vintage decoders. For exam-
ple Digitrax DN-143 decoders.
6: Consisted locos on the PCMRC layout – consistent
loco and decoder design and attention to detail allow
them to run together with BEMF activated.
