I remember when the flared radiator ones were built, delivered, and in service since November 2003 thru March 2004 and July 2004 thru October 2004

[@molossis]

Fun Fact: Around this time, PRLX (Progress Rail) had aquired many SD70MAC's and in 2019, Progress Rail spent over 7 million dollars rebuilding all of them into the new SD70MACH. They are currently starting to ride metra's rails. These will replace the old original F40's on Metra's System. (Mostly the F40PH's that were not rebuilt or upgraded.)

[@edwardfrankliniii5403]

EMD and Siemens began testing AC motors way before GE with the SD60MACs 9500-9503 for Burlington Northern. The 60MACs were outright beasts at 415,000lbs and 4000hp, 200 more hp than the standard SD60s. I witnessed them on several occasions on coal trains. These units were hauling freight long before GE introduced the AC4400CW. In fact, this is what fueled Burlington Northern’s initial 300 unit order of SD70MACs. Also Conrail and EMD began the whisper cab program with Conrail 5544 being the first locomotive of its kind. It was a testbed included in Conrail’s original order of SD60Ms. Positive feedback from crews resulted in a subsequent order for SD60Is which Conrail built from EMD kits at Juniata Also, the 4500s used to be the 700s. CSX added weight to these units increasing their weight from 415,000 to 426,000-428,000lbs. You can see the added weight plates on the side sill on the conductors side and a steel bar laid on the walkway on the engineers side. The flared radiator 4700-4800s were purchased on the condition that EMD build the units at 432,000lbs. Additionally, the 4700-4800s were delivered with 4300hp instead of 4000hp. The 4500s were also upgraded to 4300hp. CSX pioneered the heavyweight program with AC4400CWs 495-496. All subsequent CSX locomotive orders were to be 432,000lbs, including the DC units.

[@Slim_Slid]

Conrail 5544 was also purchased by CSX in later years and renumbered to 5774. It's now off their rosters and is outside New Braunfels Texas serving as a switcher at a cement facility.It was purchased by Cemex from CSX.

[@ATARP24]

I actually caught a few SD70Maces here in Grand Rapids, MI. So far, I have gotten CSX Engines: 4563, 4535, and 4554. Thanks for sharing this video!

or gp40-3, yes those exist

[@thedwaynerailfans]

Nice video I hate to correct, but there were a few noticeable errors, such as the EMDX 7000-7003 units werent MAC demos, they were SD70M demos, their DC traction version. and UP, NS, CN, and ATSF never ordered SD70MACs. CN ordered SD70I and SD75Is, ATSF ordered SD75Ms, NS ordered SD70Ms, and UP ordered SD70Ms Unless you were talking about the SD70 series as a whole and those 25 EMDs including the ex EMD demos CSX bought were SD70Ms, not SD70MACs

[@buccaneerrailfanning1776]

Yeah a ton of people have pointed that out. 4772 isn't even an ex Conrail lol, I got a few things wrong and asked people if I should take it down, everyone said keep it up but I'll try harder next time to get my stuff right.

[@thedwaynerailfans]

@@buccaneerrailfanning1776 nah u shouldnt take it down. My best bet is to probably just redo it and acknowledge the errors from the og version. even tho it still has some errors, it still provides a lot of info on what u got right

[@Flowercityrails]

This was a great and informative video! Can't wait for more engines of CSX!

[@MichaelN12]

Idk if I’m correct on this or not but I’m pretty sure the flared radiators were put in there because the units were made after 2000 which required them to be certified for tier 1 emissions standards. It seems like they couldn’t do it as easily with flat radiators and the flared ones made it easier it seems. I noticed this with all 70M’s and 70MAC’s on pretty much every system.

[@MattTheAllertor125]

2:40 up didn't own any sd70macs it was the sd70m Owning 1,452 units and csx own somewhat 25 units? And also the demonstrators. But were sold to prlx and then sold to up to continue their service life and ns also had them but also sold to prlx.

Great video! I’ve always been a big sd70mac fan and especially CSX. I remember seeing the flaired radiator models brand spanking new watching trains on the A line in NC. I’m so glad they are rebuilding them I was getting worried hunter harrison would scrap them a few years ago I’m glad his reign of terror is over lol. I’m hoping they eventually start to rebuild the newer flaired radiator models it seems for some reason those are less desirable since they chose to rebuild the older ones first. I’m not sure

The flared radiators are most likely made for extra room to accommodate for the tier 1 emissions standards at the time they were built

Technically NS, UP and CN bought 70Ms not the MACs

[@losi5ivet29cc]

CN designated theirs as SD70Is for the wisper cab isolation joint. The SD75I is close in appearance as well but has an extra blower duct on the engineers side and makes 4300hp compared to the 4000hp of the SD70I.

[@Slim_Slid]

@@losi5ivet29cc SD75M's and SD75I's both make 4,500 HP while the others are at 4,300 HP...

[@losi5ivet29cc]

@@Slim_Slid unless that is a recent upgrade I do not see that being the case I know for a fact CN SD75Is are or were 4300hp the SD70Is although similar in appearance to the SD75Is are all 4000hp. The dead giveaway between the two is the SD75I has an extra blower duct on the engineers side and a select few of CNs SD75Is are numbered in the 5600s the rest start at 5700 and go up. The SD70I is CNs version of an SD70M perhaps you should do a little more research. You may be getting confused with the recent NS CP SD90 rebuilds into the SD70ACu they were all 4300hp as well before being upgraded with new electronics and hardware that allows them to be bumped up to 4500hp .

[@Slim_Slid]

@@losi5ivet29cc I'm well aware of the SD9043MAC's that have been rebuilt into SD70ACU's from Norfolk Southern and Canadian Pacific. The reason why they were 4,300 HP is because they were given the same 710 prime movers after the 265 was a horrible example of reliability and longevity.The successor to the 265 is the 1010 which Caterpillar improvised on where EMD didn't and powers the SD70ACE-T4's. The SD75M's along with some of the SD75I's that originally were all ATSF before the merge into BNSF all have 4,500 HP. In recent times they are mostly in storage or have been retired because of no PTC and aren't capable of being used as middle or rear DPU's,also meaning they can't be used on the front of a consist unless they are trailing.

[@losi5ivet29cc]

@@Slim_Slid you're referring to the BNSF SD75M which I am also well aware of and being a close realotive or basically the same as the SD75I as being 4500hp. Ok I will give you that one but unless the 5700 series in CN SD75I fleet all have 4500hp? That would leave the early versions at 4300hp they were originally rated at 4300hp and I know railroads like to upgrade etc but they never actually update the information on I.E. the builders plate for lack of better words. Also the early SD70Ms aka CN SD70I have the 16-710G3B whereas the SD75Is all have the 16-710G3C some were EFI and some weren't aka the later builds received EFI and I can see getting more horsepower easily out of EFI by playing with mapping injector size and most times the governors the governors seemed to be the deal breaker on some of EMDS attempts at more horsepower the SD50 comes to mind as an example and as a result on those in particular they reduced the hp rating in effect making them a bit more reliable.

[@AndrewTheRocketCityRailfan4014]

Santa Fe didn’t buy any SD70M’s nor SD70MAC’s but they did buy a more powerful 4500HP version known as the SD75M. ATSF also did by some SD75I’s but merged into BNSF before they could be ordered, resulting in them being delivered as BNSF Fakebonnets. 2. CSX and NS have not been very kind to their ex-Conrail equipment. First the Ex-CR 70MACs, and then NS deciding to sell all 80MACs to PRLX and CP without even sparing one for preservation. The 80MACs and 70MAC. were among the best EMD locomotives ever.

[@Slim_Slid]

Norfolk Southern sold their SD80MAC's to Canadian Pacific to use as parts donors for the SD9043MAC's that both Norfolk Southern and Canadian Pacific purchased from Union Pacific which have been rebuilt into SD70ACU's. CSX sold all of their derated AC6000CW's to Progress Rail along with the SD70ACE's. CECX purchased a good amount of SD9043MAC's too. A few of the SD75M's and SD75I's have survived elsewhere outside of BNSF,which have put tons of them in storage along with the SD70MAC's including the BN Executive Macs.It's now rare to see any of them in mainline service unless on a local job or in non signal territory,at that. The problem BNSF has with them is that they aren't equipped with PTC and are getting up there in age and either will be decommissioned,storage,or scrapped.Rebuilds are unknown until further notice.Union Pacific is facing the same issues with their SD70M's. They aren't capable of being used as middle or rear DPU's,which includes it's impossible to use them on the front as a leader,unless you want to deal with three hours of computer errors and the system continuously resetting itself. That's why on the front or rear of consist they have to be trailing with a modern and PTC equipped locomotive and would have to be coupled behind the front units.
