Programming the ScaleTrains N Scale SD40 2 to work better with the Protothrottle

[@gmburzynski68]

You can also change the notches on the throttle its self. I to have used Tim Garlands videos in programming my ESU lok sound equipped locos. I used a Accutrax speed tunnel to set my max speed at 18 scale miles per hour. Then adjusted the speed curve. I need to change the curve to have a real fast speed at the very end to facilitate wheel cleaning. Nice video!, keep up the good work. FYI, you can also adjust the brightness of the lights and a fade in/out option. Greg

Thanks Greg! Tom’s videos are great and really helped me understand the set up. Wish I had an Accutrack speed tunnel, but on all my trips to the US have still not found one, and now I hear they are out of production. Hopefully someone else will make one! Yes, I’ve adjusted the lights on other locos, but for these just wanted to get them working better with the ProtoThrottle

You can do similar with other throttles. I use Engine driver a lot and set it to jump 3 steps per button press giving 8 throttle steps. I have 60s to full speed, 30s to stop and brakes set to 50% to match older Loksounds. I also have drive hold on the throttle for coasting (doesn't work with v3.5 and earlier). It sounds great when running slow and changing between two steps to obtain the required speed like the prototype.

Ok, that’s one way of doing it. I prefer setting that in the decoder so it will work with any throttle.

Nice video. I love my protothrottle. Had to make a few adjustment as you did. I use on my HO switching layout. Cheers

[@ChicagoSubNScale]

They’re great! Thinking of getting another one when I build my switching district

[@HartfordWhaler]

Not inexpensive but worth the price in my opinion. a Are you in SA?

[@ChicagoSubNScale]

@HartfordWhaler I’m in the UK. Moved here from SA 25 years ago

[@HartfordWhaler]

Heard the accent. Lots of model railroading in the UK. How’d you get the protothrottle there? I’ve had a couple UK subscribers say they are hard to come by in the UK.

[@ChicagoSubNScale]

@HartfordWhaler yes, there is an active US-outline modelling community here. I bought the ProtoThrottle in the US. They are not available in the UK as radio licensing regulations prohibit the sale of the Protothrottle here.

I really appreciate walking through the default settings and how/why you need to change them. I am saving this video!!

[@ChicagoSubNScale]

Glad you liked it! I have Tim Garland to thank for his excellent video that gave me the idea and helped me work out how to do it.

I wander how these throttle fare when operating across the internet? See the live stream i have on my channel.

[@ChicagoSubNScale]

Think there would be too much lag to operate reliably. I’ll have a look at the live stream when I get home later
