20-3820-1 PS4

Bad news for you, I just checked that sound file now that I know where to check- segment 241 and yours has the bad sound file too if you enable quilling whistle and then play the PFA sequence. As seen here https://ogrforum.com/...6#163180074756537156

Again, the process is simple, download the sound file from the product page.

Open with ADPCM and analyze it. http://www.silogic.com/trains/ADPCM.html

Attempt to play segment 241 and if that segment is loud static- then that is what you will get out the tender speaker when playing the PFA sequence with quilling whistle enabled at the same time.

On the passenger cars front, I would think you might like the Madison style Southern Crescent cars over the Smooth ones.

Example of smooth ones MTH 20-6517 Southern 70' Streamlined Passenger Car Set

To me the Madison ones from this set on the "bay" https://mthtrains.com/20-3463-1 are a better fit but don't think there is a full set listed today.

FWIW, I ran into a similar problem trying to find the MTH cars I wanted at a price that was good and ended up with the Lionel Southern Crescent set from 2001Lionel 6-25654 Southern "Crescent Limited" Heavyweight 4 Car Passenger Set

Here is my Crescent Limited MTH passenger car set(s).

The five car set is 20-4077 MTH date 2005, I bough it new at local dealer 2014

The two car add-on set is 20-4177 also MTH date 2005 and again bough it at local dealer 2014.

The RPO car is 20-42044 MTH date 2018 bought at local dealer 2018.  Now don't think Southern actually painted a RPO for the Crescent!?

Before getting the MTH set(s) had a five-car set by K-Line sold to a forum member after getting the MTH.

EDIT:  Forgot to add, these MTH cars have correct "names."

Edit:  Just thought about this, did MTH keep the heavy weigh molds???!
