The ScaleTrains N Scale SD40-2 is a great runner, but it is even better when paired with a Protothrottle!
In this tutorial I show you how to program the SD40-2 using the ESU LokProgrammer to work even better with the Protothrottle, slowing down the speed and matching the thottle notching better.
I based this tutorial on the excellent video from Tim Garland ( @SeaboardCentral YouTube channel – https://www.youtube.com/watch?v=qC9DkqOys1Q), so thank you, TIm! If you don’t know the Protothottle, head over here – https://www.iascaled.com/store/ProtoThrottle
