Silverliner Vs Out of Service - Technical Topics

Is this article stretching the truth a bit about the cars never being put back into service? I am not as well-versed as many in this thread about the construction of the trucks, but if they really can't be repaired, does that mean its time for a Silverliner VI?

The cars will absolutely be put back in service. I believe what they are alluding to is that the equalizer bars are most likely not repairable and will need to be replaced which is extremely labor intensive as the trucks will need to be totally stripped down.

We already know the ACS64 will fit anywhere, and the ALP44 will have a sister to keep her company in the shop....

Will the Amfleets fit through the tunnel?
I don't expect height/width to be the problem, what about length? Are they longer than the Bombers?

I guess MARC has a surplus of single levels now?

Now I'll have to get the camera out.

The Amfleets are 85' long, same as the Bombers and Silverliners. Their slightly lower and rounded profiles give the illusion that they are longer and clearance won't be a problem as the Metroliners ran into Suburban back in the 80's. I wonder if the restrooms will remain in service?

In addition, although it didn't mention it, I would assume that one of the "Amfleets" will actually be an ex-Metroliner cab car.

I kind of figured that was what they actually meant. As scotty269 said, the article was edited, it seems that the local news stations are going for the attention-grabbing headline as opposed to the truthful one.

The news story in that link didn't state the cars were irreparable, it stated the parts may not be. Therefore, I believe the cas will return to service once the defective parts are replaced. What will take a lot of time is manufacturing the new parts. And of course some time will be spent figuring out why the old parts broke, and if the existing design was adequate.

As an engineer tool maker I wonder about this problem. The equalizer is a forged one piece casting? There is a pin on the journal to capture the bar longitudinally? Are there any data of the orientation of the cracks?
Thanks for your answers.

Leased fleet to cost SEPTA $257,035 a month
http://www.philly.com/philly/blogs/real ... fleet.html

SEPTA estimates it is spending $257,035 per month to lease train cars from regional transit agencies to help alleviate the loss of one-third of its Regional Rail fleet, which were pulled from service July 1.

Per week, SEPTA is leasing five coaches from the Maryland Area Regional Commuter train service for $19,462 per week; one locomotive and eight coaches from NJ Transit for $15,570 per week; and two locomotives and five coaches from Amtrak for $16,375 per week.

Busch said an earlier statement by SEPTA's Director of Media Relations, Carla Showell-Lee, that the agency would spend $757,300 per month on the leases was incorrect. "It was a miscalculation on our part," Busch said.

Leased fleet to cost SEPTA $750,000 a month
http://www.philly.com/philly/blogs/real ... fleet.html

SEPTA estimates it is spending $757,330 per month to lease train cars from regional transit agencies to help alleviate the loss of one-third of its Regional Rail fleet, which were pulled from service July 1.

Per week, SEPTA is leasing five coaches from the Maryland Area Regional Commuter train service for $19,462 per week; one locomotive and eight coaches from NJ Transit for $15,570 per week; and two locomotives and five coaches from Amtrak for $16,375 per week.

Somehow the math doesn't add up. Based on the weekly charges, it's more like $205K per month. Hopefully Hyundai Rotem will be on the hook for all of these expenses.

The standard damages under the warranty work out to about $720,000 per month ($200 * 120 cars * 30 days), so with septa set to lose $30,000 per month there will surely be court hearings for years to come

Also, Maryland has some greedy gups down there, huh?

Hopefully Hyundai Rotem will be on the hook for all of these expenses.

If SEPTA told them to use that component/vendor, when the dust settles, Hyundai might not have to pay squat.

This will bounce around court for a few years.....

This is the internet, good sir, all we do here is vociferously speculate on minutia - not actual engineering.

There is a picture here: http://www.phillymag.com/news/2016/07/0 ... allery-2-3" onclick="window.open(this.href);return false; (3rd picture under Anatomy of a Failure), but it's not great..... and this article too. http://www.philly.com/philly/business/2 ... _form.html" onclick="window.open(this.href);return false;

But not super detailed info like you (and everyone's lawyers, no doubt) are looking for.

Thank you Alex,
I saw that one. Is there a shot of the damage out there?
I am down with the minutia. Someone mentioned welding on this part...I would be soooooo surprised by that. If the crack(s) are caused by that locator pin and follow the forging grain I have a great fix...

Not a fast fix sadly....I drive 30 minutes north to Warminster just to get on the train and go south.

What exactly are we looking at here? I can't figure out what is the equalizer bar, what is the sideframe (if at all shown), what is the bearing plate on the journal (presumably where the equalizer was sitting, and perhaps welded if I understand correctly-- it was stated the equalizer was welded to the truck...). What is the shiny part in the picture?? And, where is the crack!
Can someone help me out? Thanks, Jim S

The wheel bearing Journals slide up and down in the side frame from bumps in the track. The Equalizers sit on top of the journals and under the springs creating part of the suspension. The EQ s carry the whole weight of the car. If they are forged as I presume then the locating groove in the EQs which fit on the bearing journals is a likely place for stress to cause a Crack across the "forge grain" line.
just a guess...

The article has been corrected to reflect more accurate numbers.

Thanks. We had a similar discussion with good input from Roadmaster about the mechanics here back on Thursday (many pages ago!) If I understood correctly even though the equalizers carry the full car weight, the "front/back" (as opposed to vertical) force for braking on the car goes right from the journals to the sideframes. But I still can't figure out which part is which in that linked picture, though.... JIm S
