Based on what i saw, I guess the R179s will be also 60-footers like the R160s rather than 75 feet, since they are making 5-car sets to complete a 600ft long trainset

Delivery of the first 5 units (#3010 through #3014) began Tuesday September 6, with the arrival of cab car #3014. #3013 and #3012 arrived Wednesday night, and #3011 and #3010 arrived Thursday night.

They're going back to 60 foot cars on B division. This is because 1. Some lines can't accomodate 75 footers, and 2. On a 600 foot train, 10 60 footers have 40 doors which allows for faster loading and unloading than the 32 doors that you'll see on 8 75 footers.

2 questions of my own are: Why are the R-179's being trucked in instead of being delivered by rail? And which yard are they being delivered to? (I understand that the answer to the second might explain the first one too).

But why are they at sanitation dept "barn" ?? Instead of a "B" division car yard.

The city's Sanitation Department is right across the IND 207th Street Yard. The photos were actually taken at 215th Street, which is the north end of the yard.

Where are the R179's going to be assigned to at first? I heard that the first 4 car sets will replace the R42's on the J/Z and the 5 car sets would all go to the A to free up some of the 46's. I'm guessing those would go to the F to free up some R160's to run on Second Avenue. To get rid of the summer swap, I'm guessing they'll try to keep all the remaining 32's on the J/Z, assigning R179's to the C.

Also, does anyone know what type of propulsion the R179's will have? Will it be the Bombardier propulsion found on the R142, R142A, R143, and R188, or something else?

Yes, all the 5-car R179s will go to the A. The 4-car R179s will go to the C, J/Z, and displace the R32s and R42s on those lines to either the B or G, the reason being that they need more cars on the G to run during the L tube shutdown. Additionally, they want all SMEEs off of the J/Z due to their slower run times over the Williamsburg Bridge. With the J/Z all NTT, they can run more trains per hour, which will help alleviate the projected overcrowding.

The propulsion is a newer model of MITRAC; it sounds different from anything that currently runs in the system. Here is Bombardier R179 3010-3014 pulling into Broad Channel from F5 test track after concluding testing for the day (10/28/16):

The train sounds great actually. I've seen some comments on other sites wondering why the MITRAC propulsion may sound the way it does now compared to previous versions. Here's 3 reasons I can think of:

1) SiC-type inverters are now becoming common. These are more compact compared to the standard IGBT-type inverters, run quieter and have low maintenance costs.
2) Bombardier has started to shift towards Permanent Magnet (PM) type motors over the past 5 years. The MITRAC PM motors have been used in projects, including the S7/S8 trains in London and the C951 trains in Singapore. Here's clips of both where you can hear resemblances.
3) A combination of both technologies may have been used.

My guess personally is more likely a SiC-type inverter was used for this project.

Singapore C951 with PM motors: https://www.youtube.com/watch?v=cTspBC-Q9sc" onclick="window.open(this.href);return false;

One thing that many may not remember is that the Bombardier propulsion used in the R142A/143/188 trains was not actually designed by Bombardier. It was designed by AdTranz, which Bombardier acquired from DaimlerChrysler Rail Systems in the early 2000's. Bombardier gained propulsion technology at that time and was able to fast track their own R&D with the new MITRAC system to help get to where it is now.
