If you read the history of the AEM7's, your doing the 'crap' label no justice. They were put to service in 1977 because the E60 were crap. If you add the years up to present thats 35 years in service. Minus the last 3 years because they have been breaking down. But the only reason they have been breaking down is because they added more power capability to it with existing system. You own video, an AEM7 was only capable of 7 cars, after that 2 AEM7's, nowadays they put 13 on one.
AEM7's are more then capable of handling more then 7 cars. The HEP is the limiting factor and thats 16 cars. The only reason why you see 2 mu'd together has nothing to do with train lentgh or strength but that either 1 unit just came out of the shop and must run with another locomotive on its shakedown run, or both units have issues and need to be together.
@ghostengineer OK, I was just going off of Pentrex's Amtrak documentary which says that 1 AEM7 is rated for 6 cars (efficiency), over six and Amtrak uses two. Maybe they meant at 125mph sustained efficiency since the metroliners only carried 6 cars. But with your point i always wondered how they knew how to carry 1 or 2 AEM7's when sometimes you see only one with 9 cars.
Temple, amtrak does not own any 9000 hp locomotives. Aem7 are 7000 hp and an hhp8 is 8000. Let's not try to make me out to be an idiot. I am an amtrak engineer and run these locos daily.
Good video sir, Strange seeming 904 in front of a HHP, but the HHP units kinda suck. They overheat alot and there not that dependable so it's a wonder why it's being towed.
at njtamtrakguy tge ac units do not break down for the reasons you mentioned. in the summer they overheat due to the motor blowers being to small for the units. it has absolutely nothing to do with the battery circuits. i went this whole summer running everyday between nyc and dc and havent had a single problem with an aem 7 ac unit. all of the problems were with the dc and hhp locomotives. sorry i do know what im talking about. thank you
temple, it shows hoe very little you know. as i hsve said in an earlier comment,im an amtrak engineer out of nyc and run these for a living. only the hhp is 8000 hp hence the 8 in its name. the aem7 as built is 7000 hp hence the 7 in its nane. most hsve been derated to 6000 hp though
As someone who runs this stuff for a living, Im curious how you came up with the assumption that the 904 is a "crap Box"? Amtrak has been having a serious shortage of electrics lately, and the HHP was probably getting a ride to Ivy City for work. The HHp's are crap boxes if you ask me. The AEM7's AC and HHP's run great together and better then an aem7 combo or HHP combo. Go figure.I had this same combo a few weeks back on 67
@ghostengineer AEM-7AC #904 always tends to break down due to the battery circuit board overloading and shorting out. There are other videos of this AEM-7 being switched and towed by other locomotives due to breakdowns.
from what I've seen, both locomotives (the aem-7 and the hhp-8) seem to work best when they are lashed up together double heading.

@ghostengineer Aren't the new ACS-64 electrics going to have 9000hp?

@NJTAmtrakGuy 6400 kilowatts = 8582 horsepower which is quite short of 9,000.

One of several reasons why 904 is probably the worst AEM-7.

Awesome catch!! 5 stars! I agree this is extreamly rare!
Train538 2 years ago
that is rare if the hhp-8 wasnt broken down but u never no though
andow21 2 years ago
They may have been low on equipment somewhere so they had to put the HHP-8 on with the AEM-7. Yeah you never know why.

Nice catch!! Too bad the AEM-7 had to be 904.:(
