new issue for the ride home. pat lawson-muse is in the newsroom for us. pat? >> reporter: jim, there's a switch problem outside stadium armory which is causing delays for the blue orange and silver lines. metro already warned evening commuters that the ride could be slow on the same three lines following smoke in a rail tunnel this morning. transportation reporter adam tuss reported arking insulators caused the smoke. the three lines shut down because the issue, the problem was in the middle of a tunnel under the potomac river. that shut down forced commuters to find different ways to get to work and led to some frustrating starts for this work week. >> i've been on the metro for four hours trying to get here and should only take 20, 30 minutes on a regular day. >> the delays unimaginable. inexcusable. >> metro apologized for the delays and the inconvenience in a statement and says the shutdown was necessary to keep passengers safe. wendy?

>> all right. thank you, pat. smoke and fire issues like the ones we saw today are a continuing problem for transit systems nationwide. not just our metro. i-team's tisha thompson joins us with that angle of the story. >> we just got a look at how many smoke or fire incidents metro had over five years. think had the highest number in 2011 with 187. last year that number according to metro totalled 108. metro says they count every type of fire from cigarette butts in the trash can to bus fires but we wanted to compare it to new york's sway system the metropolitan transportation authority there told us it averages about 963 smoke incidents or fire incidents per year but that subway system is about eight times bigger than d.c. and when you take that into account the two systems average about the same number of incidents per mile of track.

tisha thompson news 4 i-team. >> thank you. closing arguments are set for wednesday for the boston marathon bombing trial. earlier today the jury that will decide dzhokhar tsarnaev's fate heard from a death penalty opponent. justice correspondent pete williams is in boston with the latest developments today. pete? >> reporter: jim, good afternoon. yes, it was dramatic testimony from sister helen, the catholic nun from new orleans one of the country's leading opponents of the death penalty. she revealed today she met with tsarnaev five times starting in march and as recently as two days ago and asked today by a defense lawyer whether he ever expressed his feelings about the victims of the bombing. and she said he said it emphatically no one deserves to suffer like that she said she thought he was sincere, she said

i believe he is genuinely sorry. note she didn't say he says he's sorry. she says she believes that he is sorry. so a very possibly pivotal moment for the defense because throughout this trial, jim he has never shown remorse and no evidence of it. he's never looked at any of the victims who came in to testify. he stared straightaway with an impassive look on his face and could be a critical moment if there is a juror who is on the fence. remember the jury has to be you unanimous to do what the government wants in this case which is to return a verdict of death by lethal injection. if that testimony can peel even one juror away which i'm sure is the deft's fondest hope then that can be critical. she did say today she felt her opposition to the death penalty might have influenced her perception and said she wouldn't have said what she said if she didn't believe it jim.
