you'll quan I've worked in many different fields from law to government to business I've even one the reality show survivor but in every part of my life I've been fascinated by the same things systems and networks we're going to go on quite a journey coast-to-coast across this sprawling land to discover the habits the rhythms and the secrets that you only notice when you step back and see the big picture interchanges oddly elegant in the next hour aerial photography and satellite tracking will reveal how America's transportation systems make us the most mobile people on earth we built the vast networks of roads rails and airwaves and an army of workers keep the wheels turning hey let's like the bus driver but it's getting harder and harder to keep all these systems running well i think the freeways will get so slow where a lot of people just decide it's not worth the grief many of them are aging designed at a time when America was far less crowded you have a disruption at one place and it ripples all the way across country it does have a ripple effect but even as he struggled to keep up every day our systems miraculously managed to get us where we need to go this is a story of 310 million Americans on the move this is America revealed yeah America revealed is made possible by the Corporation for Public Broadcasting and by contributions to your PBS station from viewers like you thank you monday morning just before dawn but this isn't the night sky this is America this is us each of these points of light represents 7,500 people they create brilliant constellations that span the continent from the faint glow of small towns to the blaze of cities like Chicago and New York to connect these dots we built four million miles of roads 200,000 miles of rails 5,000 airports the largest transportation network in history but keeping it all moving that's America's challenge in the 21st century and nowhere does that challenge loom larger than in New York City it's the perfect example of a powerful but aging transportation network that moves millions even while straining under their weight take the island of Manhattan 23 square miles home to 1.6 million people every weekday morning is population nearly doubles swelling with an army of commuters these people are essential to the life of the city getting all of them onto this tiny island in only a few hours is a daily adventure that teeters on the edge of chaos and it's about to begin at 630am I'm coming in on the red-eye from LA to JFK International Airport and I've got plenty of company reported the path of every plane landing in New York's three major airports in a 24-hour period a flight comes and goes every 24 seconds that's more than 3,500 flights a day I 7am thousands of yellow cabs are picking up their first fears of the day at the airports and heading for men hand this taxi is one in 50,000 vehicles that will leave its way through New York's necklace of bridges and tunnels in the next power just below these bridges more than a hundred thousand people are traveling to and from the island by boat these are the traces of those vessels darting around New York's rivers and harbor including one fleet which alone Carrie 65,000 commuters a day staten island ferry yeah as thousands descend on the island by here road and water even more arrive by rail long island railroad trains carry suburban commuters into Manhattan every two to four minutes along with pack trains from New Jersey and amtrak trains they all converge at America's busiest commuter hub New York's penn station while only a few blocks away trains from the north stream into another bustling train station grand central terminal but getting people on to Manhattan is just half the battle now they have to deal with this the streets run yellow with taxis competing with thousands of trucks and cars and bus routes crisscross the island adding another layer to the traffic I'm not surprised the word gridlock originated here it's ATM and it looks like nobody's going anywhere but beneath the streets it's a different story i'm talking about the subway every day this system carries over 5 million passengers citywide without it traffic would overwhelm Manhattan streets and the city couldn't function but the subway has had an even bigger impact than that starting in the early nineteen hundreds when the first track was laid to build a transportation system in America whole cities and towns will spring up around it the subway system is a prime example it determined how New York City took shape and dictate the patterns of its inhabitants lives look beneath this forest of midtown Manhattan skyscrapers multiple subway lines converge here funneling in hard-working commuters from the city's outer boroughs like Queens this is a snapshot of what Queens look like in 1917 when subway construction was just getting started and here is what it looks like today a busy vibrant borough the subway made Queens possible but how 100 years ago to combat overcrowding and lower Manhattan tenements New York expanded its fledgling subway system to the sparsely populated outer boroughs critics call them the tracks to nowhere but New Yorkers soon got onboard lured by the promise of open land just a short ride from their jobs by the nineteen-twenties these lines were carrying more passengers than they could handle the city plan to add over 100 miles of new track but first the Depression hit then World War two yeah today we're stuck with the same basic wheels that were out of date in the nineteen thirties and the number of passengers keeps going up with every passing decade it's a pattern will see all over the country enormous but aging system was working hard harder to keep up with the growth to help create it's ten a.m. in the morning commute is winding down the city has survived another rush hour and millions have made it to their destinations New York's public transit system may be old and crowded but without it this teeming metropolis would come to a screeching halt the same is true across the country are public transportation systems are what keep the nation moving there's one system that carries a whopping 26 million Americans every day more than any other form of public transport there it is there it is again the humble school bus what's up guys good morning and come to kingman arizona to meet a guy who keeps one of these yellow Marvel's moving here rush hour is just beginning for many students in this desert community buses are the only way to get to school around the country kids rely on a half-million member army of transportation experts the nations school bus drivers here let's make the bus driver when these kids are on the bus they're my kids and I'll mess and I don't take that lightly you have to be the mother the father the mediator the nurse the cool uncle like how many miles you drive every day on average all do about a hundred sixty-five miles a day and that's a few that's just me this is mike's bus it's just one of kingdoms 53 buses replanted gps devices on them and found that they drive one-and-a-half million miles every year to every corner of the school district an area the size of Delaware that's repeated nationwide in thousands of school districts large and small tho system quite like this anywhere in the world here in the US if you can't get there on foot you can get a ride to your local school even if it's not that local so you guys are really kind of like the lifeblood of the system right i mean without you these kids wouldn't even be able to get an education no they wouldn't be able to get the school now we keep pumping the kids in so they can get educated our school buses worked amazingly well which is good considering how much we rely on them but there are other transportation networks out there that face big challenges including the system that first connected the country from coast to coast and made modern America possible the railroads to create a nation wide web of tracks the federal government launched one of the most ambitious and expensive infrastructure projects in human history and for nearly a hundred year's America's railways were the fastest and most popular way to travel but not anymore to get a glimpse of what keeps our trains going and what slows them down I've come to the rail hub of the United States Chicago more trains pass through this city than any other because in the eighteen hundreds Chicago's politicians lobby to make sure all national rail lines and here that created jobs but also logistical nightmares today there are three different systems here with different needs all fighting for space on one set of tracks commuter trains making local pickups amtrak trains traveling longer distances with fewer stops but those two passenger networks are dominated by the biggest slowest network of all yeah free our economy depends on goods carried by rail from coast to coast we have the world's most efficient and profitable trade system moving nearly ten times as much as $MONEY euro it's so successful that free companies owned most of America's tracks and many of our freight trains pass through one small section of Chicago's freight yards 27 miles of track behind me will move about 1.75 million free cars each year but this phenomenal success has come at a price the system isn't nearly as good at moving something else people so what is it about the freight system that gets in our way this is Jack strength is using a remote control to push that train of a man-made he'll be call the double hump shipping companies built this hill so that men like Jack can process all the free coming through this yard and reassemble cars according to destination the network we depend on to ship our goods depends on Jack his remote control and a surprisingly simple process known as pumping pumping is exactly a slang word for classifying the cars sorting kind of like a postal facility but instead of sorting mail your starting these kinds
