There's an archived story about the history of the tunnel:

http://www.sunspot.net/news/local/bal-traintunnel.story

This is an interesting note for those wondering how the cables were
physically snapped:

"The tunnel also has a second use. An MCI fiber-optic cable trunk line
suspended on the tunnel's west wall carries thousands of long-distance
phone calls."

It seems less than a derailment could cause some damage... I assume(???)
that it's in heavy conduit of some sort, but it seems even some
maintenance or other activities could snag something and cause a similar
outage...
