MTH Premiere PS-3 Steamers?

I just acquired a French 241A steamer, which was one of the first ones released a couple of years ago. I can't comment on the quilling whistle because I haven't tried it out - the 241A may not have that feature since it was one of the first PS/3 engines. Sound is excellent; this is the first MTH steamer I've seen that uses a speaker enclosure and I think that helps a lot. I love the high-pitched scream of the Euro whistle - it transports me to another time and place. 

Here is a video from MTH about their Premier K4 with PS3:

The sound quality seems to be improving, but still not up to Legacy.

I think MTH may have abandoned their quilling whistle for now.

Sounds are comparable to PS2. Otherwise I don't find much to say supporting a 3 is better than 2 argument.

Did the PRR really have passenger equipment with grinchy green trucks?

In my opinion the quillable whistle is still better on Legacy.  As commented by others the sound quality of PS/3 is clearer and better than PS/2, but not as good as Legacy.  Quillable whistle is on Blue Goose and Southern Crescent.  However, on the Southern Crescent it is not really a quillable whistle.  The quillable whistle on Southern Crescent is a 2nd whistle different from the 1st whistle.  I don't know if K4 has quillable whistle. Maybe someone else knows?  MTH usually does not demonstrated the quiallbe whistle in their videos.  

The green passenger trucks and brown car roofs match the 1920's era pin striping on the locomotive.  Some of the other locomotive details are not correct for the 20's but hey, it's MTH.  Pin striping went away in the 30's while the green trucks/brown roofs lasted until WWII.  Black trucks/black roofs were the norm after the war.
