9001-9008 are still undergoing repairs, and some of them have already gotten the new scheme.  The derailment caused more damage than initially thought.  The first three production cars from Nebraska (9015-9016, and 9017) are up there as well.

 

I think that's only for towing purposes (the R160s could tow a R179 in theory).

 

You can clearly hear both propulsions are powered in the married pair, so it's not being towed...

Nice to see that the M9's can operate in union with the M7 sets, I doubt that will EVER happen in revenue service, but its good to know that they're capable of operating together.

Ran into someone on the M9 program today, says they wont be in service until January or February at least.

Projecting your insecurities much? He never made any suggestion that he was "superior"

LMAO did I make it look like I was insecure? I'm not gonna sit by as a Long Islander and let someone step all over us, everyone is a douchebag in the state, not just us.

Honey, if you don't want to hear cursing and see crazy people, you can move to a gated community in Utah. Whatever your conceptions may be of the LIRR, the major difference in environment between it and the subway is that you have seated yelling people vs standing ones. Long Island is not some paradise of civility -- may I remind you that it is landmass that generated the likes of Sean Hannity and Anthony Scaramucci. 

Even if it was some nirvana, though, I'd still give these arguments no importance. Transportation is one of our great societal equalisers and generators of economic mobility. Negating its potential to be thus because a privileged few are too cowardly too meet the less lucky is undemocratic and unfair to those who would benefit -- especially given that the issues described are not intrinsic realities of our transit system, but rather largely symptoms of gross political mismanagement and, well, our society. 

Edit: oops, missed this last bit. My bad. 

The stupidity in this statement, "the likes of Sean Hannity and Anthony Scaramucci". Travel anywhere outside of NYC and you'll see the same type of people. You're describing 60% of Americans right there my friend. Keep politics out of it. Everyone in New York is a douchebag, not just people from Long Island. Don't start talking like you're "superior"

1.5 kV DC and 3 kV DC are commonly used overhead catenary ratings outside of the USA. Heck, even most light rail lines in the US use 750 VDC overhead line. Look it up lol.

Why is the NEC AC then? Just the way it was from the start?

The traction inverters are what you hear regardless of what the power transmission steps are. Any difference in sounds between car classes is always attributed to the "tuning" of the inverters. That being said, differences in the power source may slightly change how the traction inverters respond to requests for power. For instance, the new Eurostar Siemens HSR sets operating under AC power sound different than sets operating under DC power.

AC overhead departure:

 

DC overhead departure (skip to 3:49):

There are DC overhead power lines??? Never knew that.

Typically power transmission follows an AC-DC-AC path. This is true for diesel electric locomotives and units drawing AC overhead current. AC power is accepted from the overhead line or the main alternator, rectified to DC for the DC link, which then supplies both the traction inverters (which invert back to AC for the motors) and the HEP and aux inverters (which invert back to AC for those loads).

In the case of DC pickup (third rail or overhead), the power supply bypasses the rectifier and enters the DC link.

In the case where multiple AC sources (different voltage and frequencies) are to be used (like with the M8s and NEC electric locomotives, etc), a transformer is provided to take the input AC and output a standard AC setting to the rectifier for the DC link.

So basically, in the case of the M7 and M9, 750V DC power is sent to an inverter which converts it to AC use for a motor? Which creates the noises heard?

M8 being different, AC - DC - AC?

What type of propulsion are they using  with the M9's ? Mitsubishi again?

Yep, M7-M9 all use Mitsubishi, its easier to swap parts that way. I believe everything is the same just the inverters are tuned differently on each unit.

I'm VERY disappointed with the propulsion. It's so bland.

Crossrail should serve as a shining example of what it could be both in frequency and integration RER as well. Your 100% it's time to rethink what's current and what was and focus on the future and what's need to optimize this vital infrastructure. The one thing you learn in studying any Civil Engineering discipline is that these are invisible to the public for the most part. If people only knew how important transportation is to there lives and all the spoils they enjoy daily it's frustrating at times.(facepalm) But I think I've stated this before the low hanging fruit IMO creating a third NYCTA rail division with FRA standards (RX & SIR) interline these routes with the LIRR and MNRR and as you stated rethink regional rail and it's integration anything within a 100 mile radius. This could be done. In fact it has too.

Then again, in Britain, they have lots of government support, on their "Federal" level. They also have a lot fewer regulations when it comes to finding contractors e.t.c., and their construction process takes much less time.

Word has it these will be moving to Ronkonkoma today coupled to an M7. They will be following train 2010 out of Hillside. Not my direct source, but keep your eyes open! 

I am 2 miles from the ronkonkoma yard, I'll go check it out and see if I can see anything

Credit to the video poster, here's another move of the M9's in Fresh Pond.

The yellow faced M9s from Japan are in the states, but they derailed in route to NYC on the freight train it was a part of. So those cars will stop by Kawasaki in Yonkers to get new trucks and to be inspected for damage.

I wasn't aware of that, but arent there 8-10 cars in NY at Fresh Pond/Hillside already?

Anyone have updates?

They're here.

It's honestly stupid and at the very least, they should've awarded the base contract months ago.

My educated guess is that Kawasaki will get the engineering award and do some of the production while Alstom will do the rest of the manufacturing (similar to the R160).  Except Alstom and Siemens just merged, and my sense is that the MTA is working out the logistics of how production will be split between the three companies.  And, unlike the R160, Kawasaki will likely still have some M9As in Yonkers while the R211s start to roll in.

I thought the M9's were being built and assembled in Lincoln, NE. Not Yonkers.

So in other words it would now appear MNRR is not getting M9's? I have a feeling the reason they decided not to go for an MNRR order is because Cuomo wanted them "cuomoed", and I doubt Connecticut would want that on trains running in their state.

The difference is more like 2 million, which, broken down over the course of a year, is negligable.

I can all but guarantee you MNR will get M9s -- they too have M3s to replace. 

The difference is not "2 million". This sourced document says otherwise

Unless there has been some change order for dual shoes, and cab signal interoperability (one which I would be delighted to hear about), they physically can not. The LIRR has different 3rd rail design, and a different cab signal system. 

As I said above, the designation in the order has changed. What I am saying now is that for the sake of clarity and brevity, until otherwise proven, it is easier to continue to refer to the different subtypes as _ and /A

Thats the only thing I'm saying. The M9 was designed with a shoe specifically for the LIRR, it doesnt have the dual shoe like the M8. Unless the MTA is proposing another design for the M9 for MNRR I don't believe that MNRR is going to get M9's at all The ridership difference is almost 20 million more passengers per year difference between MNRR and LIRR. LIRR needs new units more desperately.

The same reason they redid the interior of the derailment R46 set 6150-6153.  Politics and instant satisfaction, as well as keeping them running for at least until the last of the cars they are to retire leave the system.  Plus, they're not necessarily going anywhere just yet, and even if MNR gets M9As, it would be a minimum of 5 years before the first M3 goes, and potentially near 10 before the last one is retired.

Please stop saying MNRR is getting M9A's. M9A's do not refer to the variant that Metro North would get. M9A's are M9's that are federally funded, which are identical to the M9's. The LIRR has both M9's and M9A's.

As an upper Hudson Line rider, I really hope MNR will at least give them some extensive service if it plans on keeping them for decades from now.

The trucks are in pretty bad shape. There isn't as widespread of a squeaking issue as with the M-7s (where it can be almost intolerable at the car ends); but a lot of the cars have an extreme sag to one side, even if only slightly asymmetrically-loaded, and the some cars will rock quite violently into turns.

The seats absolutely need to be reupholstered. By my guess most of the M-7As have been, so they have no excuse. The Shoreliner seats are disgusting.

The current toilet & HVAC systems are woefully inadequate and very problematic. A peak GCT-Poughkeepsie train with only one working toilet is unacceptable, but common.

Unfortunately, Dutchess, Putnam, Orange, Rockland, and Suffolk Counties' tax dollars aren't as good as the others' in the MCTD, so I don't expect these fixes to come soon, or at all. What are we going to do, drive into the city? The MTA knows our bluff.

Lol just wondering why you included Suffolk County in there? Hudson Line doesn't even come close to Suffolk County, its way out east on Long Island, and the taxes are ridiculous in the first place.
