I haven’t acquired any DCC experience yet, but I recently ran an Atlas Gold Series loco on a friend’s layout, and I noticed the train got up to full speed long before I could make the engine “roar”.
My goal is to simulate the sound of a non-turbo EMD in the 8th notch that is straining to get a barely-moving coal drag up a 3% grade [even though the steepest grade on my pike will be <1%]. I can’t do that if I have to ease back the throttle to keep the train from going 100 scale-mph!
So here’s my question:
If I were to put in a separate sound decoder at a separate address in the same loco, would I be able to “rev it up” independently of the motor with a dual-control throttle?
With Soundtraxx diesel decoders, you don’t need to do that.
You can set a CV to indicate you want manual notching instead of autonotching synced to the throttle. Then you select a function key to do the autonotching up, say F5, and autonotching down, say F6.
It actually works kind of fun. The engine won’t move until you start it, so you press F5 and it does engine startup sounds. Now the engine will respond to the throttle. Then you press F5 to move up a notch, or F6 to move down a notch. The loco can be standing still and be in notch 8 if you like.
Joe, with my 100LC, at a high value setting for CV 3, I can do a painfully slow acceleration, but the decoder makes the diesel labour like heck while it brings it slowly up to speed. Is this not much the same thing, only decoder controlled?
i am adding 2 ac4400 kato units and the new digitrax sound decoders (when available ) to a consist of athearn
gensis mac 70s with no sound what is the best way to match the two different speeds due to the different
starting voltages.
Assuming they are all DCC you can set the start/middle/max voltage settings on each loco to make them run at the same speed on a given throttle setting. to fine tune it even more you can set individual speed steps. Oh, and I almost forgot, [#welcome]
I cranked up some momentum in an Atlas Gold Trainmaster and it works pretty well, crank the throttle and the engine revs up and loads down while the loco just barely creeps. But if you advance the throttle slowly, it doesn’t rev. Sounds great getting those commuter trains under way.
