Those, along with the rest of the propulsion system, are coming from Mitsubishi Electric Co. in Itami, Japan.

That didn't look like an overhauled unit to me. It looked like one of the teal/gray ones.

The reason why the MBTA specified 64 inches is because if a single door leaf fails, a wheelchair can still pass through.

With 64-inch wide doorways? On the A-cars, there wouldn't be any space for windows between each door pocket. It would certainly be possible on the B-cars, though.

This is just my guess, but that $728 million is the amount that is allocated in the budget for this project and not the full amount that will be paid to the contractor.

There are pictures of various parts of an Orange Line pilot car as well as a 2/3 length mock-up and an interior mock-up in the COO's report to the FMCB today. From what I can tell by the picture of the roof, these new cars will utilize self-contained, easily removable HVAC units, greatly...

It happens in the NYC subway also...look at all the intersecting lines at Times Square or Union Square. These announcements serve a purpose: to inform passengers of all available subway connections. As for the MBTA, however, what purpose does playing a ding-dong before every announcement and...

Prius batteries are NiMH, a completely different chemistry. The new buses will utilize lithium-iron-phosphate (LiFePO4) batteries.

Electrification is the way forward. The on-order New Flyer XE60s are pure electric; they don't need any catenary to operate. The most infrastructure they'll need is a quick-charge station at South Station. Not only that, but the option order of XDE60s are supposed to feature larger batteries so...

Click here for renderings. The building that's being built now is the main (only?) building. It is scheduled to be complete by April of next year and manufacturing equipment installation is scheduled to be complete by December of next year. Mainstream production of the Orange Line cars should...

From what I read in CNR's proposal, the only component that's being manufactured in China is the car body shell. The trucks are to be supplied by Bradken, an Australian company; the propulsion system by Mitsubishi; couplers by Wabtec.; etc. Aside from the first 4 pilot vehicles and the car body...

I could be wrong, but I think the new vehicles are designed with provisions for CBTC. Here is a clause from the technical specifications document of the new Red/Orange Line vehicles: The ATP supplier shall demonstrate the ability to provide a system that will work on an analog, continuous coded...

These "bus connection" announcements grind my gears every time I hear them. They help no one and only add to noise pollution. If the MBTA started announcing specific bus routes again (they did when automated announcements were introduced around 2003), they could help regular commuters learn...

Here's some optimistic news.

Does anyone know how the contractor plans to rehabilitate the Red Line reservation on span 1? The platforms of Charles/MGH extend across almost the entire span.

That article was published in 2010, when Jim Aloisi was the MassDOT secretary. Expansion efforts were reinitiated after the 2013 transportation bill was passed, but I'm not sure where negotiations with the USPS stand.

Re: Driven By Customer 'Service' Parte Dos The green light is a propulsion fault indicator. I'm not sure what the red light indicates.

Re: Driven By Customer 'Service' Parte Dos They are diesel-electric hybrids in a series configuration. The diesel engine isn't mechanically connected to the wheels; it spins a generator which charges the batteries and/or sends electricity to the traction motors. Sixty were ordered and they are...

Looking at the upcoming construction activity for GLX, the announcement on Monday may be for the start of phase 2.

Re: Driven By Customer 'Service' Parte Dos One or more of the DE60LFRs also has the new seats.
