Athearn has announced MP SD-40’s in RTR series with 2 numbers in the 3000 series and 2 in the old 700 series. With DCC and Sound and without. DCC-sound series is reasonable $185 retail.

I’d have to think six axle road units would have been too heavy.September 29, 2015 at 9:03 pm #7289bargetanikaParticipantToo bad, I like the way they look.
October 16, 2015 at 9:49 pm #7353Jim DobbinsMemberOK, Athearn just announced a new release of SD40s including MoPac with the large Eagles on the sides.
I’ve been studying photos of MoPac SD40s in the early scheme with the large Eagle on the side, and comparing them
to Athearn’s listed “options”.
Any one like to comment on these offerings, re: the brake cylinder arrangements listed??
It appears MoPac did some miss-match truck change-outs over the years on these units.I’m having a hard time finding photos with the exact brake cylinder arrangements Athearn is offering.
I’m planning/hoping to get two units, one that’ll be kept as a MoPac unit, but…
the other unit is going to be transformed into a C&NW “Blue-Devil” :~)Any help appreciated, TIA,

October 17, 2015 at 1:02 pm #7355Jim DobbinsMemberOK, I guess I didn’t see the other two earlier posts on the new Athearn SD40s in MoPac.
My question concerning the brake cylinder arrangements…
I have noticed that some units must have had truck change-outs done to them as there are at least a couple units with mixed up brake cylinder arrangements.IF there is anyone here, that has an ear at Athearn, maybe it could/should be pointed out that some of the unit numbers they have chosen mostly DON’T match the brake cylinder arrangements they are offering or, maybe, that my observations are really just that, and are mostly relative to different points in the timelines of each unit?
I’m guessing Athearn’s choices are photographically documented somewhere…?
Just in case, I’m planning one ordering two units, one of each brake arrangement, and then do some side frame swapping to get the correct arrangements I need. ;~)

I have a photo of 734 from 1972 showing it with high mounted brake cylinders. At some point when 734 was renumbered to 3034 it received high/low brake cylinders as the 1978/80 photos show. It was painted to the last Jenk’s blue paint scheme prior to February 1980.
The undated photo of 738 show it to have high mounted brake cylinders. When it was renumbered to 3038 the 1977 photo shows it still to have the high mounted brake cylinders.
The two photos of 3039 that I have – one undated and the other from 1984 both photos show high mounted brake cylinders. The 1984 photo shows 3039 with a double eagle. A photo from 1969 of 739 (previous number of 3039) shows it with high mounted brake cylinders.
The two photos of 3041 – one undated and the other from 1983 both photos show the high/low mounted brake cylinder option. I don’t have a photo of 741 to compare.
I’ve sent a message representing the MPHS Manufacturers assistance group to Athearn to provide assistance with the models and if you see anything else I’ll pass on the information. I now have a point of contact and hopefully will fix any issues.

#3034 is one I am going to model. This photo has the right look to capture my interest in modeling it. The weathering is GREAT!
http://www.rr-fallenflags.org/mp/mp3034gea.jpg
I have to disagree with you on Unit #738. I see it having hi mounts up front both sides and hi/low on rear right and low on rear left. This is a not so great example, but I see only one high mount brake cylinder on the rear right.
http://www.rr-fallenflags.org/mp/mp738bpa.jpg
Found this photo of 3038 dated 06/1976 and it has high mounts up front and High/low rear. The rear is low mount on the left and hi/low mount on the right
http://www.rr-fallenflags.org/mp/mp3038gea.jpg
#3041 front is low mount on the right and hi/low on the left. All high mount on the rear.
The truck combinations are very important. If Athearn is touting detail specific models. Ask if they plan on adding the air dam behind the inertial filter screens.

October 21, 2015 at 10:27 pm #7369Jim DobbinsMemberNate & Brian,
There is also this shot, in which the 738/3038 is the trailing unit.
It appears tome to have the high/low combo under the radiators, and
the all high mounted cylinders under the cab.http://www.rr-fallenflags.org/mp/mp738bpa.jpg
I’ve decided for my needs to order one of the 738 w/sound for sure,
but I’m still undecided on the second unit.
I need fond out which, the 3039 or the 3041, wore the large Eagle when
it went to the C&NW. Both did, but I want to be sure.
Maybe both did still have the Eagle, but I haven’t found any certain proof…
yet.
I guess I may have to ask on the C&NW group at yahoo to find that answer.Thanks for both of you helping.

October 21, 2015 at 10:29 pm #7370Jim DobbinsMemberWhoops there!!
I entered the wrong url on that photo.
It should be…http://www.rr-fallenflags.org/mp/mp787bpa.jpg
Dan Schmidt
October 22, 2015 at 1:22 pm #7371James PruittParticipantYes Dan, 738/3038 does have a combination truck configuration.
This type of detail is what makes modeling MP SD40’s fun. I’ll be building my SD40’s from various models. Kato/Athearn/Atlas/P2K.
Kato frame, drive and gear towers.
Athearn truck side frames and fuel tank.
Atlas long hood.

October 22, 2015 at 9:08 pm #7372Jim DobbinsMemberC&NW had a few of their own SD40s riding on mixed trucks as well, and,
as we’ve determined, so did MoPac.
I still haven’t gotten a response yet on the C&NW list as to which MoPac units
that went to the C&NW still had the Eagles on the sides…I guess, with the two units I just ordered, I can at least have one with mixed
trucks. Like I said early on, one of them will get the C&NW patch job done to it.
It’s just a matter of swapping side frames and patching lettering. :~)I just realized…I still have a couple more “spare” Athearn Undec. RTR SD40s with both sets of side frames included. ;~)
Dan Schmidt
October 22, 2015 at 9:54 pm #7373James PruittParticipantDan,
When mixing side frames, you HAVE to have one side as low mounts and the other as a hi/low. Not both sides as low mounts. For instance. this is one of the units I am going to be modeling http://www.rrpicturearchives.net/showPicture.aspx?id=1869765. The rear trucks is hi mount on both sides. The front left as you can see is a hi/low mount. The other side of the front truck (right side) is low/low mount only. Look at the clasp and slack adjuster between the first and second wheel. The low mount brake cylinder is between the second and third wheel. Now if you are modeling a unit that has high mounts on the front and hi/low on the rear, then the hi/lo side frame would be on the rear right and the low/low would be on the rear left. No exception to that rule.
And being the stickler that I am, it is not just an easy add a hi mount brake cylinder. The clasp is different also and the the single low mount brake cylinder is turned around.
Brian
October 23, 2015 at 3:20 am #7374Jim DobbinsMemberThanks for that info, Brian.
I am personally aware of how that works with the mixed brake cylinder arrangements, but maybe others aren’t.
It’s good to point stuff like that out, J-I-C.Also, I did get a response, re: the C&NW “Blue-Devil” units from Kurt Kruse
over on the C&NW/yahoo-groups site.
He reveals that the only unit in the group C&NW got, that had the large eagle on the side of the car body was the 3044.
The 3039 & 3041both at least had the number’s size & location re-done,
probably both were completely repainted at that time?
I also found out the 3039 was one of MoPac’s “Double-Eagles”.
So, as it works, I’ll use the 3039 I ordered, re-number it to 3044,and patch it
with a C&NW herald on the cab.
I’ll figure out what to do with the 738 later… :~)Dan Schmidt
October 23, 2015 at 9:31 am #7375madonnasuffolk30ParticipantBrian,
Can you fully explain the brake cylinders so I can pass the information to Athearn? I am unaware of the rules with the cylinders and I want to understand what is correct and what is wrong and why match up like they do.So for example are these combinations correct?
Truck 1
Left side high/high
Right side high/highTruck 2
Left side high/low
Right side low/lowTruck 3
Left side low/low
Right side high/lowNo go’s ???
Left side high/high
Right side low/lowNate
