Here's the Robertson Rock Train in Riverside Westbound on 3/12/24
Along Dewey ave.
I caught this one since I just happened to have time this day after being laid off from my job.

Why eat morning Del Taco Burrito at the restaurant, when time is better spent having it trackside in Riverside!
I though maybe these LPG units may have sounded slightly different?

Sorry to hear about the layoff Jim.  Nice video, the sound is a little different.  And those hoppers sure look different, are they only used on the rock job?

Those aren’t LPG units. Just regular GE’s that may be running on biodiesel. If biodiesel is used, it may smell different but the sound will be the same.

LPG is an entirely different fuel than Bio-Diesel.

Bio Diesel can smell like things that are cooked in corn oil and such....as what you smell when you cook those things is the oil itself to large degree. French Fry smell is what I here most often.

Are the emissions less with the biodiesel?

Jim, thanks for the video!  Sorry you got laid off.  

Ideally some day I'll be on an overpass when the Rock Train goes by to smell the French fries or whatever.  The pedestrian overpass at the Fullerton Station is an excellent location for the sound of exhaust and smell of diesel fuel.

BrightLine uses a mix of conventional diesel fuel and the biodiesel fuel.

Sounds about the same as conventional diesel.

They're owned by the customer and only used on their trains.

Yes is down grade Westbound here, also approaching a signal, right behind the previous Riverside local I posted about 03:38, on same track too I think.
