Eric, thank you again for a great review. Not being an NW fan, it is still interesting to watch the quality reviews that you provide.
With that said, can someone reference some time points in the video to explain the "sounds changing from simple to compound"? With all the comments over the years I thought I would be able to pick up on the difference, but I can't.
I di hear the starting chuff and I hear the "higher speed" passes that sound like the regular chuff, just faster.
Thanks.
Charlie
Charlie, The time point in the video is 19:58-20:02ish. Because Eric has sequence control enabled it gives you a better reference point. In sequence control the bell stops chiming at speed step 24. The transfer of simple to compound happens at speed step 25. As you roll through using sequence control it is hard to tell because of the bell. This is the only point in the video that this happens. The reasons are many. One the sounds is only activated by a logic block that is similar to the wheel slip on the VL BB. here are the rules.
1. The simple sound is only active after a dead stop or initial startup.
2. Simple sound is only active up to speed step 24.
3. When speed step 25 is commanded the sound changes to compound.
4. Compound is active for the rest of trip until you stop. Yes even if you drop below speed step 25. You have to fully stop to allow simple sounds.
So you never hear the sound again because Eric never completes a full stop. The only chance the sound had to make the switch was at the initial roll out but is hard to hear because of the bell.
I have attached a video that was posted on a different thread. The change happens at 8 sec.
Eric, Great job with your review. I love to watch your layout.
Thanks for the explanation & video! Nice to know those little details.
