Will the older cars be phased by age (the A/Bs from early 1970s first) or the C units first?

I have no idea. Many of BART's railcars have been refurbished over the years, but I don't know how much difference that will make.

A big reason for getting the new ones is the difficulty of finding spare parts for the existing ones -- many of them have gone out of production over the 45 to 50 years since the oldest cars were built.

C cars should be going first, as they have never been overhauled.

On a different note, does anyone know the fleet numbering for the new cars?

As far as I know, 3000 series for the D (cab) cars and 4000 series for the E (cabless) cars.

2 New BART Cars Go Out Of Service - YouTube -- because of some unstated problems with them.

Some people grumbled about the lack of Wi-Fi, but it apparently isn't installed yet.

I rode the new BART train! - YouTube
and several other videos there. I see it, therefore I believe it. :D

Did anyone figure out the make and model of the propulsion engine? Sounds very similar to the WMATA 1000 trains.

It's a Bombardier MITRAC system as the Bombardier site has confirmed this in the past. BART likely has a variant of the MITRAC DR1200 series motor combined with a variant of the MITRAC TC-1410 or TC-1420 IGBT inverter module. They definitely use the MITRAC TCMS for the monitoring system. Now what BART has is not the only system that has a similar sound. Usually most of the propulsion motors/inverters rated at 1000VDC or above will have the higher pitched whine.

Examples of other Bombardier systems sounding similar are below:
Shenzhen Metro (1500VDC): https://www.youtube.com/watch?v=O3ef_VAhzzE
Guangzhou Metro (1500VDC): https://www.youtube.com/watch?v=ki78NHPcT4U&t=1s
Rome Metro (1500VDC): https://www.youtube.com/watch?v=IdEockO0mb8
Madrid Metro (1500VDC): https://www.youtube.com/watch?v=JVnidJwDC-E
BART (1000VDC): https://www.youtube.com/watch?v=EE5OaurgBeY

The one thing I noticed between all of them is that BART is slightly lower in pitch running 1000 volts of current compared to the other systems running 1500 volts.
Gotta love Alstom. Every year on opening day of hunting season, it is a paid holiday! :wink:
