UP C40-8 pack

[CBQSD24]

Hello! Hope this isn't the incorrect thread to put these in, still figuring the forums out haha. Anyway, recently I've taken it upon myself to make a more modern-ish C40-8 lineup, as an addition to what's included with the APL trainset from TS. There also seems to be a lack of Dash-8 reskins in general, and I think its time someone filled void. My goal for this pack is to represent just about every variant of UP's C40-8s post 2000-ish, from the CNW patches all the way up to those two units that got flags and wings. I've done some reskinning/content releases for open rails before (see my container packs on trainsim community), as well as I've done many locomotives in trainz, but nothing to this degree in terms of open rails. I like to think I know what I'm doing, but any feedback/suggestions are wholly welcome and encouraged. If anyone has specific road numbers or variants they wanna see, please let me know. I'm gonna try and aim for around 8-10 units. I'll post updates in here about as often as I can.

The lineup for now is as follows (subject to change, information not fully fleshed out):
#9299 - flag/wing/yellow frame/red rear numbers on radiator - DONE
#9351 - flag/wing/lightning stripe/yellow frame/red rear numbers on radiator - DONE
#9300 - yellow frame/lightning stripe pushed back/red rear numbers under board housing
#9278 - red frame/lightning stripe/flagless
#9091 - red frame/wings/lightning stripe/flagless/red rear numbers under board housing - DONE
#9174 - yellow frame/no lightning stripe/flagless/white numbers on radiator
#9056 - Ex-UP patch for Citicorp Railmark/yellow frame/white numbers on radiator
#9080 - Ex-CNW patch/red rear numbers under sand hatch
#9089 - Ex-CNW patch/safety-reliability logos on longhood/red rear numbers under sand hatch
#9068 - Ex-CNW repaint/lightning stripe/flagless/red rear numbers under board housing

9351 is the first one I've started, think I got a fresh-ish armor yellow down pretty well:

More 2000s - mid 2010s UP era stuff is planned for the future as well, as the UP foamer inside of me definitely wants to cover lots of things. Suggestions on what could come next are also welcome.

I moved the thread into the modelling forum and it looks like you are off to a great start on what will be a popular set of locos. Years ago I did UP 9089 on the Diesels West model and still have some of the reference photos if you need any (just PM if so). I did it at the point where the safety & reliability logos & cab numbers were getting pretty beat up, but I like it that way.

Thank you! I'll definitely head your way once I start that unit.

Pay attention to that dynamic brake air intake. Early Dash8s including most of the B-boats had it on the roof, which became problematic in terms of rain ingress.



Later Dash8s and Dash8Ws had the air intake relocated to the engineer's side. The changeover happened somewhere in the UP 9200s.

If you need photos of specific units, I’ll be happy to look through my slide collection and see what I have…

Regarding the dynamic air intakes, Little confused there. Are you implying I should remove those vents on the roof for certain numbers above the 9200s?

If you happen to have anything for any units listed up there, that would be much appreciated!

If I had to stick my neck out I'd say the design change geepster mentioned came at #9250. Just skimming through some pics on rrpicturearchives.net the 9240's don't have the side mounted vents but #9250-55 all do. That's not the most thorough "research project" of all time though so if you wanted to be absolutely certain have a look what photos they have when you decide what road numbers you want.

Edit.... sorry, you have picked your numbers. As far as I can see only #9174 has the DB intake on the roof. The rest have them on the side like geepsters #9334 and my #9089.

So if I'm understanding this right, 9174 should look like the right side, with the vents and all, and the rest should look like the left with them covered up? And then I guess I remove the side dynamics on 9174 and leave them for the rest of the units? Still not sure if I'm entirely understanding this correctly, this is all new information to me lol.

Hey Jackson.... here's a couple of pics that might help. The conductor's side of both versions are the same. #9174 has the DB intake on the roof but all the others on your list have them moved to the driver's side as with the pic of #9300.

Edit: If you're using the APL trainset then you'll need to do some texture tweaking for #9174 to remove the side mounted intakes and put them on the roof like geepster's #9101 example but the intakes will be right for the rest of them.

Thank you! I think I understand now. Seems like it should just be as easy as patching over the intake textures on the side, as I did with the ones on the top for the other units? I dunno this kind of texture editing isn't my expertise but Ill give it a shot

You're welcome and if you want to pm your email address to me I can send you a pic you could do a "reskin" of the section with.

The APL set C40 textures came with both roof and side grills, in error. For those under 9250, the side grills need to be removed. For those above 9250, the roof grills need to be removed.

Pretty much every SLI C40 pack has issues here. For example, the CSX coal set had neither grills present.

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.

Sure, I will do that later today. Thank you.
