Doppler Effect-Lionel

Personally I don't care either way.  I just don't think that is a feature worth the effort.  My opinion.  If I had my preference I'd rather have coupler slack.

The Lionel VL Centipedes offer a doppler-like effect where different sounds come out of each unit to simulate a doppler effect as the Centipedes go by.

• VISION DIESEL sounds - Two speakers in each unit with unique sounds in each engine mixed for the ultimate in sound fidelity

As Eric from Eric's Trains described it: "4. The sound effects on this thing are killer. There's no way to describe it accurately in words. The coolest thing (to me) is the horn. When you blow the horn, it sort of "echoes" to the second unit and results it this amazing doppler-ish effect. I've never heard anything like it...which is what Vision Line is all about."

Good evening

Personally I like the Doppler option, and the coupler slack is good also. I also like the squeaking brakes.

I consider it a nearly worthless feature - it is realistic only if you are in one particularly position when you activate it - so I'm not the least bit concerned it's not my locos.

The Lionel RailSounds horns sound like recordings of moving trains anyway. The Doppler is recorded into it. Not as dramatic, but it doesn't sound like a static horn.

I would bet MTH has a patent on it, so don't look for Lionel to do it.

If you have ever heard a horn when the train is not moving it doesn't sound as good.

No big deal for me.

Not a deal breaker for me.

For those not familiar with the doppler sound effect here is the MTH engine so equipped. It should be noted that with Doppler the sound waves  are compressed in front of the source and expand after the source. I think it is a cool effect and has been offered on numerous DCC sound decoders like Tsunami, LokSound, etc. Like crew talk, if you like it then leave it on, if not then turn it off.......it just adds another dimension of realism.   http://www.youtube.com/watch?v=1ud3iqHK9ws
