CHicago METRA electric problems

Line had a problem with spectuclar electric flashes. Maybe just a PAN fouling the DC CAT.

There’s DC cat in the North River tunnels? When did that happen?

Another problem this morning with the CAT.

Surely there are cell-phone pictures of the event ‘up close’ or the aftermath.

Let me save at least some of you from having to experience that hell of a newspaper site with its adware ‘opportunities’ and self-loading follow-on items of ‘interest to you’. Here is the picture that ran with the morning story:

I suspect this is a stock picture, as I’d think it extremely unlikely that a train producing that kind of light show from 3000VDC* (edit:1500VDC - thanks, Erikem) would have its pans on the wire this morning, apparently with the shoes none the worse for wear. But I did notice that in the pictures last night, all the fluorescent lighting in the cars stayed on … surely the battery emergency lighting in case of “CAT” failure doesn’t run the whole load!

From what I saw in the ‘fireworks show’, I’d have expected there was a burnthrough through enough of the catenary structure to allow it to sag down to come close to, but not necessarily contact, the carbody. Presumably the blue-green color was partially vaporizing copper…

*Who can tell me the correct BBcode for ‘strikethrough’ on this site, now that we have these idiot enhanced smileys?

1500VDC, not 3000VDC.
