Is 4-cylce a better term? EMD had 2-cycle engines as opposed to the 4-cyle engines produced by GE and Alco. This H engine was something new for EMD and apparently was not successful.
@@josephcipar3666 The 265H was the worst motor that EMD ever made,the development of it was rushed and not carefully worked out. The biggest problem was the harmonic balancing which was fragile and resulted in the locomotives having broken crankshafts,shattered mounts,and fractured frames.All four SD90MAC H2's from Canadian Pacific were scrapped but they kept the SD9043MAC's and rebuilt 30 of them into SD70ACU's. The SD9043MAC's were all convertibles but still had extra motor mounts for intentionally when they would've gotten the 6,000 HP H motors,if they were both reliable and successful. Union Pacific faced the exact problems and sent their SD90MAC H2's back to EMD,which ended up as exports to BHP Biliton.Some were scrapped as well. Union Pacific ended up keeping the SD9043MAC's for awhile. 110 of them were sold to Norfolk Southern,39 to Canadian Pacific. The units under Norfolk Southern were all rebuilt as SD70ACU's and then all but 45 were sold to PRLX, before recently being scrapped. CEFX has retained most of their SD9043MAC fleet.
All of the SD90MAC H2's had EMD 265H's which were four stroke.It was the first,the only,and last four stroke motor EMD manufactured and it was another massive failure. The H motors immensely suffered from internal vibration that caused motor mounts and crankshafts to be broken.Terrible harmonic balancing was the cause and the crankshafts should've been redesigned.Canadian Pacific owned four of them and they were scrapped shortly after debution.They did keep the SD9043MAC's in which thirty of them were rebuilt as SD70ACU's. However,a handful of SD90MAC H1's had the 265H's because most were the SD9043MAC's.Union Pacific and CEFX were the only other ones to own these units.
265H não foi o único. Hoje temos o 1010J que usa o antigo motor 265H como base, claro com todas correções de erro de projeto do motor H e também com tratamento de emissões para atender a norma EPA Tier 4.
Listen to that beast! Shame I was too young to ever see these in action!
This is one of the only videos of this engine in service. Thanks for the upload.
Thanks. I have video of the 9303 in service, too.
Sounds just like an AC4400CW
I have video of the 9303, too.
I remember riding this unit in 2015 in Wilkie SK canada to Sutherland Sk. A wild ride. I was on the 9303 too
I think I also have a video of the 9303. I'll have to look for it.
I didn’t know they had WCH e bell in Franklin park 2004
Maybe I have the date wrong for the video, but I don't think so.
The tracks in Bensenville on Irving Park Road were raised by Canadian Pacific in 2017.
And I think the crossing just south of there, at Roosevelt Ave., was eliminated.
Was it a spur?
The Calgary built 9100 series SD9043Macs were far superior quality with whisper cabs built by GMD in London Ontario
What do you mean
4 stroke ?

The H engine sounded real mean
Yes, I heard them only a couple of times.
The one on my layout howls at full speed
That look like sd70acu
That is sd70ace isn’t sd90mac
Check out the date on the video. . They didn't have the SD70ACe then.
Nope. SD90MAC.
CP doesn’t have SD70aces they have SD70ACU’s
But is sd90mac h2
