I’ve never gotten to hear a Leslie before. Sadly I’m in MN where there isn’t spots where you can sit there all day and watch the trains a lot only have 1 train a day. And a lot of quiet zones so you barely get any horn action here in MN

All of the Warbonnets, NS 6765.

Interesting that your thumbnail photo is actually a Prime 920, which is a copy of the Leslie S3L that has been retrofitted with Leslie RS back caps and diaphragms. It was quite common to do this as the original Prime parts wore out, retrofitting the horns with the RS parts gave them extra life. I have a former BN PM990 (the Prime equivalent of the Leslie S3K) similarly modified by the railroad and is an excellent sounding horn. I believe that such retrofits were just slightly more mellow than the original Leslie RS horns because of subtle differences in internal bell casting shape and how heavy the Prime castings are compared to the Leslie castings.

8:07 that things engines are screaming

Leslie RS3L is my favorite horn Nice catches and video

There is SD30s with this horn some of them museum and short line running.

I caught the NS SD40-2 and N&W that same day with Gavin, it was beautiful hearing that nice RS3L. These horns are my favorite, but K5LLA's are also cool to hear.

Leslie, the sound of the 90's.

649’s and the NS SD40-2’s RS3L. The best RS3Ls I’ve heard in a very long time.

Amazing Warbonnet captures!

That NS SD40-2 At The end was TOP NOTCH

Excellent, nothing beats the Leslie KS3L airhorn blasting down the track with full freight and a nice fleet of freight diesels leading the pack.

I just don't understand why these horns have been replaced.

awesome video and catches. that is a sweet horn.

Great video! My favorite horn!

Amazing video!!! I love those horns -Austin

AWESOME horn video keon

Late to this video, but sweet compilation! I love those RS3L's.

Nice, I’d say my favorite would be either the first clip or the last clip

I got a chance to here 649’s RS3L last summer. It was sounding a bit raspy but yet it was still it’s one of the most soulful sounding horns I’ve ever heard and it was hauntingly nostalgic (especially at 4:30 AM).

Nice

I might be biased but my favorites where on the BNSF units.

I need some help. Can someone tell me what air horn type was used by Ontario Northland on their GP9 II diesel locomotives?

Ok, 1st, this is an Awesome video, and the RS3L's on Warbonnets are the best, 2nd I love the classic EMD sound, 3rd, Why are all BNSF GP's always leading really short trains?

Good job!

NS 6775 is a really shitty RS5T
