    Interesting, thank you both for this information. I must ask though, when looking at pictures online, 9174 seems to be the only one on my list without side grills? I looked up pictures of 9068 and 9056, both of which fall under 9250, they have side grills:

    And then I look at the pictures ossie posted above of the 9174, and that seems to be the only one I can actually find on my list without the side grills.
    The two units you mentioned (#9056 & #9068) were both ex-CNW units and there was quite a lot of them in the 90** range and they all appear to have had the side mounted intakes. UP's dash 8 order started at #9100 and ran through to #9356. If you want a couple more with the roof mounted intake, any from #9100 - #9249 would appear to be correct..

      The UP originals were 9100-9355. With 9250 being the cutover, it appears the last 100 were the improved design, with the last 6 9350-9355 probably warranty protection units. Warranty protection was a "thing" back then.

      The CNW orders (becoming UP 90xx series) were also split. The first 30 CNW 8501-8530 also had the roof intakes. The rest had the side intakes.

        Update time !!

        My progress so far, 3/10 largely done. There's still a few kinks I need to work out with these, especially on 9091 as I'm not happy with the size of the UP text on the sides. (Been trying my best to match these things to my collection of photos I've gathered but that's proven challenging sometimes) The numbers on the rear of 9299 and 9351 could also use some quick adjustments I feel. Regardless, this marks all the units that (to my knowledge anyway) received flags and wings. There *might* be more that I have yet to find but quite frankly I feel like this is enough for this pack in terms of variety and all. Any feedback/suggestions always welcome, I'm not perfect so there's bound to be more issues I haven't spotted. Gonna try and chug out the remaining non-patches tomorrow.

          Hello! Been a few days since I last did anything here, personal life & mental health bs and all, blah blah blah. Regardless I'm finally back at my computer, and I'm currently polishing up the 3 C40s that I've done so far. First step involves covering up those pesky roof intakes that all but one on this list do not come with.

          Looking at my reference pictures here, there seems to be a little handle of some sort that I'm unsure how to replicate. I've just copied the existing plating for now and this seems to do the job, but if anyone is heavily bothered by this (lookin at you, rivet counters ), one is free to throw textures I can borrow my way. I don't think this is as glaring of an issue though.

          Other final touches are still being worked on, such as fixing the rear numbers on both the flagged units. More updates to follow this week, suggestions/feedback always welcome.

          Actually, before I forget, I've considered buying the CNW trainsets and doing the Ex-CNWs on that model. Are there differences between the two that I should be aware of? I'm unsure if I need to buy that pack as well and add that as a requirement for the Ex-CNW C40-8s in this pack. From what I can tell there's no glaring differences based on what I can tell via real pictures, but its not like my eyesight is perfect lol. (Far from it) Any information on this would be greatly appreciated.

            I dropped the CNW 8504 texture onto UP 9101 (UP is the 1st loco) and there's a few small differences between the 2 models but nothing that looks like they can't be interchangeable if people only have 1 set. The one thing that jumps out is the difference in the colour of the step side hand rails. I'm not sure why the white isn't showing up on the UP loco but it probably wouldn't be a deal breaker if there's not an easy answer to it. On the upside the CNW units only have the DB intakes on the side, so no messing around with the roof unless you want any in the 8501-8530 range geepster mentioned.

              Looks like (via what I can tell from pictures anyway) most of those roof details, like the beacons or K5H horns, were axed when they went onto UP. So I guess I'm good to keep it as just the one pack. I don't think the missing extra fuel cap is anything to worry about lol.

                Oooooookay! Time to dust off this thread haha. For those that didn't see my container thread, this project is still alive and ongoing - just took a back seat as my personal life and transferring everything to a new computer got in the way. I've sorta changed plans with this project, and instead of every C40-8 I have planned in one 10 pack, I'm gonna split these into two 5 packs so I can get these out faster. I've already got 4 done as mentioned above, and I will soon start on a fifth, and hopefully have those first 5 out by next month. I try not to set deadlines as I suck at sticking to them, but I can easily whoop up another one within a few days and have the first 5 out, and worry about the rest later. I'll probably switch this thread over from solely being out my UP C40-8s to the other projects I have in mind (Ex-SP SD70Ms, SD60Ms, etc), but for now I am nowhere near starting that. No pictures of anything ingame yet, but I did stumble upon something really cool a few weeks ago that I am going to attempt (((attempt))) to make for this pack.

                Apparently, GE's trucks (up until the Hi-ads it seems?) were made to be pretty interchangeable with eachother, thus allowing for older trucks to be placed on "newer" locomotives. Come to find out, a fair number of C40-8/C40-8Ws on the UP ended up with swapped trucks, presumably from older U-boats the UP retired around the time the Dash-8s rolled in. There are more instances of this, as I found on a trainorders post, however this is the only image (well, one of a few of 9142) that I could dig up that's clear. 9142 seems to have gotten this truck around 2005, and lost it sometime in 2008. It will become a part of this pack. Nash has kindly given me trucks off his U-boat for use in this project, (cannot thank him enough!) and so I guess I am now in the business of learning how to swap trucks. Figured this would be a fun way to learn something new. If I ever do a C40-8W pack, I will also do one like this. If anyone has any more photos of Dash-8s with older GE trucks, please shoot them my way, references are always nice. :-)
