panic as crews race into action. this afternoon, the investigation into just what went wrong and what seems to be an all-too-familiar scene for metro riders. good afternoon. i'm jim handley. >> i'm pat lawson muse. our top story this afternoon, more problems for metro. the national transportation safety board has launched an investigation into yet another incident along metro's red line. it happened this morning near the farragut north station. according to a metro spokesperson, the front wheels of the train slipped off the tracks on the red line. darcy spencer has been working this story all day. she joins us live now from northwest washington with the latest. darcy? >> well, hi, pat. that's right. officials were saying here on the scene today that the front wheels of that six-car train popped the track down inside the tunnel very close to the farragut north metro station. about 10:15 this morning. but now sources are saying that the train apparently derailed itself to avoid a potential collision. the sources say that the train got on to a pocket or side track for unknown reasons and the train sensed that it was going to run a red light. there's a lot of censors and equipment and safety equipment. there was apparently a sense that it might run a red light and apparently derailed itself. we're trying to get more information about this. witnesses say that the train was going very slowly through that area and some of the witnesses told us that they barely felt the derailment. it just felt like a little bump. 345 passengers were on board the six-car train. now, the impact dealt with mainly the first two cars. so the remaining four cars were basically unaffected. three passengers suffered minor injuries. two of them, we're told, refused treatment. one person was taken to the hospital. but, again, those injuries are described as minor. now l of the passengers got on to those remaining four cars and those cars were then taken to the platform here and they were able to get off. now, as we said the national transportation safety board is investigating the cause of this incident. about two hours after the impact, the station was reopened. it remains open at this hour, although we're told that the trains are operating slowly at about 25 miles per hour as they come through this area. we'll have more coming up on "news4 at 5." we'll send it back to you. >> darcy, thank you. well, we caught up with a few passengers who were on board that derailed train. they described what they saw and felt >> a jolt, several jolts. it seemed like we were hitting something. and then soon after we stopped, the operator said that we had derailed. it appears that everybody is okay. the lights were still on, but we were in a dark tunnel. and then later on, they sort of dimmed the lights and everything. we just waited and waited until something, you know, happened. they finally decoupled the front two cars, which i was in one of them. the front car. and then they pulled back the rest of the cars. it just took a long time to do everything. >> well, i smelled smoke like a stop before it derailed. and we got maybe two or three minutes from that last stop and we heard a thump and a bump. and the train sort of tilted to the side. and the lights went out. and we were sitting there. then the conductor came on and she said that we had derailed. stay calm, you know. so everyone was -- they were really calm. i understand there were more problems in the back car. but our car was fine. >> only three people suffered minor injuries in this latest red line metro derailment. the derailment is only the latest in a string of incidents involving metro over the past year. there was a minor collision involving equipment during the last weekend in january that went unreported for days. there were no injuries. late last month, two metro workers were killed when they were struck by equipment while working on the track bed on the red line. back in december, there was a close call for a team of independent safety inspectors nearly hit by a train that they say was traveling full speed. in november, three workers were hurt when one train hit another in the west falls church railyard. then back in september, a train hit and killed a technician in virginia. in august, a piece of equipment hit and killed a worker at the vienna station. last june, nine people were killed when two trains collided on the red line. in january of 2007, more than 20 people were injured when a green line train derailed at the mt. vernon station. and in november of 2006, two metro workers died after being hit by an empty yellow line train near eisenhower avenue. and be sure to stay with news4 and nbcwashington.com for continuing coverage of today's derailment. we'll have much more coming up right here on "news4 at 5" tonight. and we're following breaking news now in northwest washington. we're told a pedestrian has been struck. tom sherwood is on the scene at this hour and can tell us what's happening there. tom? >> pat, we're here at georgia avenue and piny branch road. if you go over there, we'll show you where the fire truck. they just pulled that fire truck up to block. there's a woman who was crossing the street on georgia avenue. she was struck by a car. i saw her sitting on the ground talking to people so i think she's going to be okay. they have her in a neck brace. it made a meshere on georgia every with cars trying to get by. there are police cars trying to keep the traffic moving. again, the woman -- i can't tell how seriously she was hurt but i did see her talking. i saw the ambulance personnel come up and put a brace on her. i think an ambulance is still going to come and take her away. it's just one example of the difficulty in getting around the city streets in washington with all of this snow. we had a more light-hearted moment a short time ago when we were in northwest washington, we heard the mayor talk about the snow removal and those kinds of things and someone asked me last night, well, what would linda kropp have done if she won in 2006? so i went by her house. here's a little of what she had had to say. somebody was saying to me last night, and that's why i came by your house, they said i wonder if linda is glad she's not mayor with all this snow. >> well, i'm telling you, this was a very hard job, but i think the city has really done a pretty dent job in getting the snow up. it's been more snow than we've had in years. and they've done a decent job in getting it up. >> how does a political person balance that expectation with reality that this is more than you could have ever planned for? >> i believe you just ve t say that it's more snow than we usually have. we don't budget for it. you have to manage expectations, not try to let people think that it's going to be done overnight. >> again, that was linda kropp who ran for mayor in 2006. here's a live picture of georgia avenue. an ambulance has just arrived for a woman who was struck by a vehicle as she was attempting to cross georgia avenue. there's lots of traffic, lots of snow. it's a very difficult situation. that's it from here on georgia avenue. we'll check out what's happening there on the street and be back to you later in the show. >> thank you, tom. d.c. mayor adrian fenty publicly thanked the plow crews today who are in their 15th shift of full deployment since last friday' full storm. >> there hav been bobcats, tractors and plows. lots of other places. these guys up here have been working around the clock. we don't have any equipment that's not being used. we don't have any people who work for us who aren't breaking their backs. we'll get to the rest of the streets as soon as humanly possible. >> d.c. snow emergency is still in effect tonight. vehicles can't be parked on snow emergency routes. d.c.'s national guard completed 500 missions during the back-to-back blizzards and they're on stand-by for a possible storm next week. the d.c. guard braved 55-mile-an-hour winds to transport metro, police, firefighters, and medical personnel, too. they have 12 humvees stationed at all seven metro police precincts, fire stations and d.c. homeland security. they've also used 60 transportation personnel along with additional soldiers and airmen. all this despite not having two of their major units. one is deployed to saudi arabia. the other to iraq. here's a live look outside right now. once again, we saw it today, nothing but sunshine. >> looks like we could see another round of winter weather, though. veronica johnson is on post in the storm center. what's the latest word? >> that's on the other side of the weekend, jim. before most of us go back to work with monday being pridents' day. a little bit of light snow. out there today, some more blue skies, more melting across the area. now, there will be high clouds moving in. that's going to come from a storm that's just down to our south. it is producing snow in areas that you might not think would have snow. like birmingham, alabama, and through areas of even southern mississippi. there's been some snow today which we'll show you in a few minutes. right now washington, d.c. is at 37 degrees. that has been our high temperature for the day. the low, 28 degrees. we'll find temperatures just a little lower, by four or five degrees comin up during the overnight period. 35 to 37, that's the range in temperatures through the area. a light wind. again, more cloud cover moving in to night. here's the system coming up for monday and tuesday that will produce a few inches of snow. this one will be making its way southward through the area. it could be intensifying right along the coast again just like some of the other systems have done. again, still the emphasis is on the lights. we'll see more icy conditions by morning. more weekend melting. again, we'll talk more about this storm coming up for monday afternoon and tuesday morning in just a few. >> all right, veronica. thank you. well, this has been a crazy rush hour for commuters if you call it that with many people still not back. luckily school traffic wasn't part of that mix. megan mcgrath looksa s at how i went this morning. >> reporter: a different day, a different challenge. yesterday's bright sun caused some of the snow to melt and the run-off froze overnight. the ice this morning was everywhere. >> i'm stuck. i tried to get out. there's ice everywhere. it wasn't like thi yesterday. now i can't go. >> you're in the snowbank. >> yes, yes. the icebank or something. >> reporter: the return to work, inevitable. but not exactly easy. this morning's rush hour, terrible. whether lanes were lost to snow or damaging potholes, the result was gridlock. not much better for those taking the bus. while clearing the streets, the plows threw tons of snow on to bus stops. commuters were perched like mountain goats on top of huge mounds of snow. and watch out for people walking in the street. many sidewalks are still buried in the snow. >> it's not even plowed at all. you pretty much have no choice but to walk in the road. >> tough getng here today? >> yeah. >> reporter: clear roads or snow-packed roads. like so many things, it can be a matter of location. green haven place is a narrow dead-end street in fairfax county. not exactly at the top of the list for snow removal crews. and it's still a mess. melissa vazquez has had trouble getting to work because of the snow. she's worried that her boss might not believe her. >> it's a mess, yeah. i know, it's hard because when i call in for work, they don't believe me because the main roads are clean, but my road is not well at all. >> reporter: a lot of people are off on monday for presidents' day, so traffic should be lighter than normal. snow removal crews are hopeful that with that lighter traffic, they'll be able to continue with their efforts and that things will improve by tuesday. megan mcgrath, news4. >> and as megan mentioned when all that snow is cleared, it leaves behind a whole new problem on area roads. potholes. we found someretty big ones around the beltway today. drivers were having to maneuver around one on the interstate 66 eastbound ramp to the outer loop of the beltway. there were several large potholes where the outer loop meets north branch ridge. potholes are caused by water getting into cracks in the road when the water freezes, i expands and makes the crack, which can turn into a really big hole. >> they're popping up everywhere. stay right there. "news4 at 4" is just getting started. health scare. >> next, what we're learning about that hospital visit by former president bill clinton. and the latest on his road to recovery. then at 4:30, it's

offered this assessment. >> one of the by-passes was completely blocked. he didn't have any damage to his heart. >> doctors expect a full recovery and say mr. clinton could be back to work as soon as monday. patrick kennedy has decided not to seek reelection to congress. he plans to release a taped message that will air this weekend on rhode island tv. in that, he says his life is taking a new

for reelection comes less than a month after republicans won control of the senate seat held by his late father, ted kennedy. surprising news on the economic front today. january retail sales were up. but the good news is being offset by the negative economic impact of this week's blizzards. steve handelsman has our story. >> reporter: today's big snow will have the same kind of economic affect say the experts as this week's blizzard struck the middle atlantic states. when people are fighting a storm, they're not shopping. >> it closed down traffic to malls, shopping centers, grocery stores, restaurants, all of that just essenally gets shut down because of the storms. >> reporter: in washington, d.c., the blizzard is over, but snowbanks still block ray's deli. it was a bad week. no money coming in? >> no money is right. >> reporter: ironically, the january retail report out today showed a surprising jump. sales up .5%. but today, the airlines are getting slammed again, more than 15,000 flights canceled this week. trucking has been a mess for days. still, experts say most of the snow's economic effect will melt away. >> i think it's going to put a dent in earnings and spending and it will slow down growth this quarter, but it won't be any permanent damage. >> reporter: that flat-screen tv that people planned to buy yesterday, they can still buy tomorrow. when malls and stores expect to be jammed. but this stormy week is the week that february employment is being measured by surveys, so economists worry that the february unemployment number will be higher than it actually was. i'm steve handelsman, nbc news, washington. again, despite the good news in january, analysts already know consumer confidence dropped slightly in early february and economists say the biggest threat to recovery is the reluctance of consumers to keep on spending. this season, national day of mourning in haiti. it's been one month since the day the deadliest earthquake struck

unlicensed contractor convinced an 80-year-old resident he needed roof repairs and in the end, the resident signed a contract to replace his entire roof. we're talking this morning for $20,000. montgomery county offers these tips so you don't fall victim. first, do not be rushed into making a decision. you could easily be overcharged or a contractor could do more damage than good. ignore the door-to-door appeals. consider someone you know or someone recommended by a friend or a neighborhood. if you hire someone, make sure the firm is licensed in your county. before settling on a price, get a detailed explanation of the service charges and ask if labor charges include travel time. people forget that. also, make sure you get a written estimate with an invoice listing the parts needed to make ever you do, always pay with a credit card. never pay in cash even if the contractor insists on it. that is a red flag. pay with a credit card. that way when the service is done if you don't like it, you can contest the charge. now we need to -- as you clean up after old man winter, there are some things that should be simply left alone. elizabeth of northwest washington wants to know

gutters, best thing to do is to call a roofing contractor. be very careful, folks knocking on your door. really, just say thank you but nohank you. if you want to hire someone, call someone you know
