The Washington D.C. Metro area has subway system linking many portions of the city with the surrounding areas in Virginia and Maryland. The system is used by many on a daily basis and allows the Washington area to operate when snow blocks the roads and minimizes traffic on the already congested streets. As the original tunnels expanded outward into the suburbs those who lived on the edge of the lines are forced to travel a very long time at a higher cost to get to some areas even without switching trains. For example someone who hops on at Shady Grove will have to take near an hour to reach Glenmont even though they are both on the Red Line and geographically realtivly close.
After years of planning and screaming a new line is in the plans known as the Purple Line. It would connect both sides of the Red Line to the Green Line. With an estimated completion date of 2020 at a cost of roughly 2 billion that some are saying that it is too expensive and that we should just use buses. In fact the portion of the line that runs through PG County mirrors some bus lines which opponents claim makes the rail line redundant. Many who support the line just don't want it in their backyard.
The problem is that buses consume fuel, have high maintenance costs and are limited in capacity. Rail is clean and can transport many more people than the buses can. Not to mention that buses share the road with cars. Even when they have express lanes they are bound to the same problems that cars have. We need to build the Metro system up with more rail lines instead of buses. Instead of arguing over the cost of building it people need to look at the cost of not investing in light rail. Look at the long term emissions, the lost productivity of those late to work and the maintenance of a fleet of buses which wear out rapidly. Long ago virtually every large city had trolley cars. Those lines were shutdown when the automobile spread, quite probably at the insistence and financing of big auto. We are not back to where we were before the loss of the trolleys and we need to play catchup in the light rail efficient public transportation business that we used to excel in. Other countries around the globe keep expanding their systems, and Washington D.C. as the nation's capital needs to set an example. We need to say that the future is worth investing in.
