    I once saw a Orange and White F unit going to Ozark running backwards. I was young but I remember it looking very odd.

    I used to ride my bike on Lone Pine which parallels the track here.

    Interesting spark arrestors on 575. Were those home made? Looks like a box with a hinged screen top on it.

    Later in their Frisco careers, many of the GP7s that had the angled spark arrestors ( which was the most common type ) ended up with these boxy versions. What I think that actually happened was the angled spark arrestors were rebuilt into the boxy ones. In some side on photos, you see an angled weld seem that matches the pattern of the angled spark arrestors.

    Seems like they'd be pretty easy to scratchbuild with bits and pieces from one's scrap bin. Never realized that these were a thing; thanks for noticing and thank you, Paul, for the background.

    Best Regards,

    Details West was out of stock, so the engine house crew had to fabricate them!

    It's my understanding (from the Fort Smith Frisco guys) that the Fort Smith roundhouse shop crews developed those box spark arrestors. The were purportedly more efficient in exhaust flow as well as spark suppression. That's is supposed to be the reason you'll primarily find them on the engines that were assigned to the Fort Smith roundhouse for maintenance. (I want to think that was GP7's 570-632... but I could be mistaken. Long time ago. Didn't think to take notes.)

    Very interesting, Andre. Whether it's homebuilt spark arrestors, or homebuilt or repurposed 4300/4400 Mountains, I'm always fascinated when I hear stories of the Frisco itself finding a better way to do things, build things and so forth.

    Best Regards,
     
  11. Any ideas what the patch under the number board is from/for?

    Thanks,Steve
