Saw them from the Beltway. When I went behind USDA to get a closer look I noticed the 5th car. Was unable to see the number.

I am not even going to speculate as to why it is there.

PS

WMATA's connection to the common carrier railroad network at Greenbelt Yard is now fully restored. Looks like it has seen traffic recently. I think the track work contractor that did the Silver line used the connection to bring in take out their track work building equipment.

The prototypes testing and evaluation program is scheduled to run about 3 months. It began shortly after the prototype set arrived on the property back in late December early January.

John - is the parking garage for the commissioning facility itself? That seems like a big expense. Is it simply because a garage takes up less space than a parking lot, and space is at a premium there?

The image is cropped from the original unresized picture. It was rotated 2.5 degrees because I held the camera above the security fence to get the shot and color corrected (red shifted) because the picture was taken under an overcast sky in the late afternoon.

No.

Yes.

The new parking garage increases the total number of employee parking spaces on the property. No new parking spaces were added when the new back shop was built a about a half dozen years ago. That's one of the reasons why the rail roadeo is now hosted at Branch Avenue yard. Part of the footprint of commissioning facility sits on an area that use to be for employee parking. The ground level of the parking garage is not for parking, it will be used for under cover storage.

Hopefully the first 7Ks will enter service soon and finally begin the 1K retirement party just like the TTC H4 & H5's when the TRs came!

Here is some footage that was captured by Fox 5 showing some of the testing that is taking place. A couple of times, you can hear the Toshiba propulsion at work.

So far, it seems that the only major issue has been that the new railcars were sealed too tight, so air would get stuffy inside. Apparently that has been fixed. Other than that, it looks like Kawasaki has put together a very nice railcar.

This whole 'sealed too tight' thing is a bit curious. I mean, the doors rattle a lot allowing in some air, but how else does air circulate if NOT because of the HVAC system? I'm now worried about that system if somehow a well sealed traincar gets stuffy.

SchuminWeb ended up posting some good videos of the 7000 series propulsion on YouTube earlier. However, I am going to let him do the honors of posting the links.

Anyways, what I will say is that the Toshiba system definitely sounds unique to say the least.

The links I have below sound nearly identical to what he posted.

Those thing are LOUD! Most of what I am hearing sounds like gear noise. The 1k cars prerehabilitation were considerably quieter.

Both the 1K and 2K cars originally came with CAM controlled DC propulsion, iirc. That type of propulsion is fairly quiet.

"Fan Railer"

I am well aware of that fact. I road aboard them and saw run bys more the year before the first segment opened in March of 1976.

It should also be noted that the 3k cars also had DC cam controls in them when new. The 4k car are still equipped with their original DC choppers.

When accelerating at p5 from 0 to about 20 MPH you could feel the acceleration rate change as the cam rotated changing from parallel to series-parallel to series and dropping resisters from the circuit feeding current to the traction motors. It felt like the changing of the gears in a manual transmission except considerably more subtle. An electrical engineer friend of mine described as multiple kicks in the ass.

the older Toshiba systems sound much better than these, sounds weird and obnoxious.

example of older Toshiba propulsion engine: http://www.youtube.com/watch?v=3zw4enZNU-U

i'm surprised to see those blue colored trains still running on the seoul metro, they must be ~30 years old at this point.

I am excited for the Silver Line to open, but I am much more excited for the 7000-series cars to begin rolling the rails for revenue service.

The tweeties are saying that the test trains are rolling through the red line, spotted at union station today.
