Update: CSX train derailment

It's not uncommon for empty conduit in the ground to accumulate water,
sometimes very dirty water. The usual quick fix is some compressed air in
one end and all the goop hopefully comes out the other. Be sure to let
anyone around the other end know before you turn on the air so they can
clear the end of the cable. Imagine Old Faithful as a cold mud bath... :)

I asked a resident who happen to work
in the area re: the 30kft temporary fiber run. See
<http://www.sunspot.net/news/local/bal-traingridlockmap.graphic>
for a map.

	It must be in a tunnel.  I drove right past there today on
	my way to work and didn't see anything at all.	The Sun
	{newspaper} is on Calvert St. between Center and Orleans.
	There are no visible aboveground cables (phone, electrical,
	cable) on Calvert or on Guilford for as far as I can see
	from the windows right now.

There was a later reference to pipes blocked with mud. Do we
infer they got permission to run it through storm sewers?
In any case, that was fast work by the fiber folks..
