Should all concrete tracks on the Red Line extension be replaced for safety precautions?
I've studied a report on the Red Line extension of the Harvard through Alewife Tunnels. I'll have that up on YouTube soon. The next time you hop on a train at Porter Square and I have study the speed limit and the curves inside the tunnels. Take the inbound train from Porter going towards Harvard Station. As the train starts to go 40 to 50 mph. The train will start to rock 3 times as the train rides down the hill inside the tunnel between Porter and the first emergency exit inside the tunnel after passing two XPASS signs, a walkthrough to the outbound side towards Alewife. The third rock really rocks the train sideways when it goes 50mph. Leaks from the tunnel extension is cause by bad contracting during the Red Line construction.
The reason why the train rock sideways is because the concrete ties connected to the rails is uneven, which causes the train to rock. Which could cause the train to derail. The same thing will the Orange Line leaving Mass Ave going towards Ruggles, as the Orange Line hits the face point/trailing point crossover going 40 mph, the train wheels bounces off the tracks. Another safety issue.
In 1988, the outbound train from Kendall used to go 50mph to 40mph as it hits the curve entering Central Square. The train rocked so hard they reduced the speed to 25mph entering Central Station.

Inbound Train Leaving Davis Square Reduces to 25mph
Back 15 years ago, an inbound Red Line Train leaving Davis Station going 40mph on a right curve passing two 'XPASS' signs. As soon a the train reaches the 'EXIT' signs, the train starts to bounce. T operator officials made a decision to reduce the speed to 25mph 'til the whole entire six car train passes the 'EXIT' signs to resume the speed of 40mph.
Don Saklad is interested in trains now?
And they're not even gay library-abusing stenographic-withholding trains?

So this is a campaign to get speeds reduced from 50 to 25?
Because the crawl into harvard isnt bad enough? Because the incline from charles towards park isnt frustrating enough?
Screw you all.
Wow. translate.google fails on that post. What can I do?
Holey Moley. What language is that opening post in? I tried a translate.google (English to English) on that post and it still made no sense. Will baby, what are you trying to say?
Can anybody help Will out? What's he saying?
Not a Red Line Tunnel Expert!!
If you want me to explain the details to you that might be boring to you, or if you're a regular Red Line rider from Cambridge, I'll be happy to detail the story on the Red Line extension.
Was you around when the construction took place in the late 70's into the mid 1980's, or did you live in Cambridge or you're not familiar with the Red Line system? Should I give you some history on those tunnels? Let me know!
The same thing will the
Safety issue to be sure, but it's kind of fun if you're standing at the far end of a car. ;)
Back Bay Station's Leaking!
If you go into Back Bay Station on the Orange Line, the shield-gutter pans connected on top of the ceiling redirects the rain water leaking through onto the tracks which rottens the concrete. Another bad constuction during the Southwest Corridor construction during the 80's. I wonder if those were the same contractors that did the Big Dig Tunnels that are leaking inside the Tip O'Neil Tunnel?
Not as much fun as the Dover to Chinatown incline
Arborway, that rough patch is not nearly as much fun as the rockin' and bouncin' you got going down the incline from Dover into the portal before Chinatown, but I guess it'll have to do.
Really bad rocking
I noticed this between Harvard and Davis, particularly after Porter Square. The train heaves, pitches, and rolls really strongly ... I don't even think of standing up until it slows for Davis Station, particularly if I have my folding bike to wrangle. It is very hard to stay upright or move in this section.
Now I know why ... and why it is getting worse!
Why don't you, you know,
Why don't you, you know, ride the bicycle?
(Regretting asking, already. But I can't help it.)
Wow, an unintelligible post
Wow, an unintelligible post about someone's eccentric personal research! Thanks for the reminder this is a blog!
Noise?
Weren't the concrete pads installed wrong to begin with? There was rubber padding that was installed wrong, which made the train ride deafening. I think they went back and retrofitted something, but the ride north of Harvard is still deafening on the trains.
