Green Line Type 9 Procurement

At the Green Line forum Brian Kane made the claim that the concept drawings were not the final design and we shouldn't draw any conclusions from that.

These ones look more streamlined & aerodynamic, meaning that their contoured design would help them travel a little faster. :cool:

The present Type 9's still look less aredynamic and very boxy looking. Plus their suspension systems leave much to be desired. :eek:

At least, the wind will be able to flow better while the B line is stuck at traffic lights.

Yeah, I think that the Type 9 trolleys would benefit best by being used on the D Line, since the station stops are further away from each other.

The travel speed is about 40mph in most areas - the maximum speed level for all trains & trolleys on the rapid transit lines. :cool:

And was suppose to be 50 after all that rail work. Had to grip about that.

Yeah, you're right!!

They are very slow in traction about making things better for the system. It is just a mismanaged & broke dismal system that is just so ill-timed and out of line!!

The intense amount of effort spent by them raising the fares every few years, it could be better spent by them improving & updating their equipment in a more timely and efficient manner!

I remember the last few years ago, when they said that not only would they be raising fares then, but also, that they would be cutting back on service, and also, that if the state gov't didn't help provide financial help for them, they would've wanted to raise the fares yet again, after raising them the first time! :eek:

Is it your contention that the time MBTA accountants and managers spend pouring over balance sheets and revenue projections would be better spent ballasting tracks and installing new signal systems.

BTW, the tracks along the D branch in Newton are perfectly suitable for operation greater than 40 mph. That limit is a policy directive based on past incidents and general rider comfort.

I thought the highest speeds in the system were the Orange Line southbound from Community College to North Station?

The station distance isn't that great that it would result in any material operational efficiencies.

Yeahhhhh... lets not just start pulling facts out of nowhere, okay?


IIRC, the Braintree branch was designed, and briefly operated around 60, which has slowly been hindered over the years. With all the equipment/track issues, the OL may be the faster line now. It's most certainly not the green.

The GL speed reduction is mostly due to how top-heavy the cars are, they start swaying a lot at speed. Even so, the D branch was still allowed to operate pretty quickly, until this happened:

Reports in the Boston Herald said that at the time, the trolley was doing about 38 or so mph at impact into the trolley in front of it. Two miles below the speed limit.

The momentum of the trolley barrelling toward the other one was so great that it struck the one on front of it with such tremendoue force, knocking it off its front bogie and derailing it instantly, resulting in this massive destruction of the two cars involved and the tragic death of the operator Terese Edmunds.

But that was not the only incident on the Green Line. There were 3 more in which for all three, the operator in the 2nd train behind the first one had caused a collision. The operator in that one had zoned out just before the crash.

1. One was caused by cell phone usage (texting his girlfriend) between Government Center Station & Park Street Station.

2. This one was caused by the operator zoning out at the Boylston Street stop. He had only just began his shift 3 hours after leaving his other job.

3. This one was caused by the operator going way too fast at a track switchover between the Kenmore & Fenway stops, causing the trolley to derail and crash into the side wall. :eek:

It's a 40 MPH cab signal code from Community to North Station.

The Red Line has 50-mph code for long sections of the South Shore Line from Braintree to JFK, there are also some short sections of 50-code in the subway between Broadway and Andrew and between Central and Kendall.

would it be so hard to get something that looks like this?

I mean besides the pearl clutching that will happen

That is freaking awesome, and totally wrong for the aesthetics the Green Line should have.
