Thanks for the -- unintentional -- photo. It's the only view of a DX from overhead that I have ever seen!
(It looks as if the locomotive in the photo is in pretty much the configuration GE built it in: my understanding is that at least some of the re-built units now LOOK radically different. ... The hood, I assume, is the same width as on domestic U- and -7 series locomotives: it certainly looks VERY, VERY wide on a narrowgauge platform!)
The bad thing about images on this forum is that they tend -- at least when viewed with my browser from my computer -- to cover the text, so I haven't been able to see what you wrote. If the moderator doesn't (is unable) to do anything about your post in a few days, would you mind re-posting the text of your message? Thanks!

What are the fundamental differences between the new 'GEVO 12 engine' and the FDL engines in the Dash 9 units? How does a 12-cylinder powerplant do the same job as a 16-cylinder one?

I had an opportunity last week to watch two CSX ES44DC's switching cuts at Dewitt Yard in Syracuse. It was the first good opportunity I've had to see and hear these units at work, and I came away with the impression that when the GEVO's throttle up they sound more like a Genesis P32 dual-mode than a Dash 9 freight unit. I also noticed these locomotives seem to produce a deeper bass sound than I've heard with other GE units.

The GEVO cylinders are larger than the FDL cylinders. That's why they're able to get comparable horsepower with fewer cylinders. It's also a much newer design.

The GEVO-12 is basically just the 12-cylinder version of the HDL-16 used in the AC6000.

Welcome aboard!

I moved the photo to the bottom of your post. That should eliminate any viewing problems.

Also, you should be able to edit your own posts. If you are unable to, you may wish to contact the site webmaster for help.
