I have a Bachmann EMD GP40 - DCC SOUND VALUE Equipped Locomotive purchased on Oct. 1st 2023 which is running fine.
I wanted to get another DCC locomotive to run consists with this one and purchased another GP40 but only DCC ON BOARD on July 29-2025. I did not need the sound function.
I tried to match the two but the new one is not consistent with the speed.
i.e. with one throttle setting, it changes speed. Where as the older DCC sound value runs consistent at any speed. Also the new one does not like to run and slower speed.
I programmed both using the speed table.
