McPherson Square's namesake died 150 years ago today

Washington has many squares and circles named after generals in the Civil War. McPherson Square is no exception, named after General James B. McPherson, who died 150 years ago today at the Battle of Atlanta.

McPherson was the second-highest ranking Union officer killed during the Civil War. At the time of his death, he commanded the Army of the Tennessee, and his death elevated General John A. Logan to command.

Logan would later lend his name to Logan Circle.

McPherson was killed in what is now the Inman Park neighborhood east of downtown Atlanta. The Battle of Atlanta, fought July 22, 1864, was largely a stalemate and led to a 6-week siege of Atlanta, which finally fell on September 2. The city was later burned by order of General William Sherman on November 14, 1864.

Interestingly, the statue of James McPherson in McPherson Square was cast in 1876 using the metal of Confederate cannons captured in Atlanta. They were melted down and recast into his statue.

A 360-degree painting and diorama of the Battle of Atlanta is on display at the Atlanta Cyclorama in Grant Park (not named after Ulysses S. Grant), and prominently includes General Logan riding to the front. He commissioned the painting to bolster his vice presidential campaign in 1884, though he died in 1886 without ever seeing the completed work.

The Battle of Atlanta was part of the Atlanta Campaign, and led to Sherman's March to the Sea, which split the Confederacy in two along a line from Chattanooga to Atlanta and on to Savannah.

Here are the answers to whichWMATA week 14

On Monday, we posted our fourteenth photo challenge to see how well you know Metro. Four of our readers took photos of different stations. Here are the answers. How well did you do?

We got 35 guesses on this post. 10 of you knew all five. Great work Aaron, AndrewB, Justin...., yest2kwasi, Sand Box John, Russell, Phil, Peter K, nativedc, and PieSuperPac!


Image 1: Brookland. Photo by Sand Box John.

The first image was taken at Brookland. The clue here is that the platform is curved. Only two stations in the system have a curved platform, and the context here is clearly Brookland rather than Silver Spring. 23 of you knew this one.


Image 2: Huntington. Photo by Peter K.

The second image was taken at Huntington. This is at the south end of the platform, where one regular-sized and two narrow escalators ascend to the southern mezzanine. I believe these are the only narrow escalators in the system.

But the real clue is the funicular on the left. This elevator is unique in the system because it does not ascend vertically. It ascends diagonally, just like the escalators. Only 15 of you knew this one, so it was the hardest to answer this week.


Image 3: Stadium/Armory. Photo by Peter K.

This picture shows the northern entrance to Stadium/Armory. There were three clues visible in this image. The yellow banner at the top is very distinctive, and says "STADIUM THIS WAY," pointing passengers to the correct exit for RFK Stadium.

The entrance itself is a clue, being unique in the system. Instead of ascending to a floating mezzanine, the escalators lead directly from the platform to a mezzanine in a different room. The unique feature here is that the opening for the escalators goes very high above the platform.

The third clue, just visible to the right is the junction indicator above the outbound track. These are present at each of the stations where trains split between lines.

31 people got this one right, the highest total this week.


Image 4: Farragut North. Photo by DC Transit Nerd.

The fourth picture was taken at Farragut North. While many stations have floating mezzanines, the one at Farragut North (for the exit to the southwest corner of Connecticut and L) is unique because of the buttresses that link the mezzanine to the vault wall. The other mezzanines are supported only by columns down to the platform. 18 of you guessed correctly.


Image 5: Grosvenor. Photo by Ben Schumin.

The final image shows Grovesnor station. This station is in an open cut, like White Flint, though the context here (no tall buildings visible to the north) demonstrates that it can't be White Flint.

We got a few other guesses for stations in cuttings, but they all have different roof types, which is a key to guessing the correct station. There are only 4 above-ground canopy types in the system (though that will increase to 6 when the Silver Line opens) plus a few unique designs.

26 of you guessed correctly here.

Thanks to Ben Schumin, DC Transit Nerd, Peter K, and Sand Box John for submitting photos! Thanks to all of you for playing.

Next Monday, we'll have 5 more photos for you to identify.

A "wye" is out, but a second Rosslyn station may make more Blue Line trains possible

Metro's planners have been studying ways to deal with the capacity crunch at Rosslyn station. A track connection from Court House to Arlington Cemetery isn't possible, but a second station for the Blue Line is, and could be built by 2025.

Each Metro track segment is limited to 26 trains per hour (TPH). At Rosslyn, where the Blue, Orange, and (soon!) Silver Lines come together, this limits the number of trains on each line. In 2012, Metro reduced the number of Blue Line trains to allow more Orange Line capacity. Later this month, the number of Blue Line trains will decline even more to make room for the Silver Line.


Two possible fixes for Rosslyn. Image from WMATA.

There's really no way to alleviate this crunch without additional track capacity. Eventually, it's likely that a second subway across downtown will be necessary to handle the ridership. Metro is currently exploring the idea of building a new loop line through the central city. A new subway would allow Orange and Silver lines to each have 13 slots, and the Blue Line could also to have increased service up to 13 TPH.

Earlier, Metro was looking at two ways to address the capacity constraints. One concept was a "wye" track connection, to allow trains coming from Court House to turn south and go toward Arlington Cemetery and vice versa. The follow-up study this year, though, determined that building foundations make this option impossible.


Potential location for a second Rosslyn station. Image from WMATA.

The other option, though, is feasible. It would require building a second station one block west of the current Rosslyn station. This new platform would connect to the existing Rosslyn station with a pedestrian tunnel. At least initially, only the Blue Line would use it. The Orange and Silver lines would stay in the current station.

If built, this would mean that the Blue Line would only operate between Franconia-Springfield and Rosslyn (though some Yellow Line trains might still start and end in Franconia as they do today). That would mean that, at least until the line is extended across the Potomac, Blue Line riders would need to transfer to an Orange or Silver line train at Rosslyn to get downtown. But all the lines at Rosslyn would be coming more frequently than they do today, which might alleviate the inconvenience of changing trains.

These diagrams I made last year show how the new station (and the infeasible wye) could work.


View peak service levels: Pre-Silver Line   With Silver Line
Possible solutions: Blue Line terminal Wye (rejected)  

Note: Since this graphic was created in 2013, Metro has announced there will be 5 TPH per hour on the Blue Line once the Silver Line opens, rather than 6 as shown here.

The wye would have allowed for more trains on the new Silver Line tracks and given riders from Alexandria and south Arlington a one-seat ride to Court House, Clarendon, etc. (if they caught the train every ten minutes going that way), but it also would have made service more complex, added chances for delays, and not fit in as well with a future Potomac River crossing. A new Rosslyn terminal would hopefully be just the first segment of a crosstown subway through Georgetown.


Possible extension to Georgetown.

Right now, Metro's planning staff is recommending the proposed station be moved forward for project development funding, which essentially means that they want it to get money for more detailed study. But the project is in the Metro 2025 plan, so planners anticipate that this could be opened within 11 yearsif the jurisdictions, particularly Virginia and its cities and counties, are willing to pay for it.

For the next few years, the capacity crush at Rosslyn is likely to get worse. But this project might be the light at the end of the tunnel for Blue, Orange, and Silver line riders.

Ask GGW: Why can't Metro keep more trains on the Blue Line?

With Silver Line opening soon, Metro is reducing the number of Blue Line trains running between Pentagon and Rosslyn. Reader Daniel W. wants to know why Metro is doing this.


Photo by Adam Fagen on Flickr.
Could GGW offer some insight into why Metro is increasing headway on the Blue Line instead of clearing room in the tunnel by running fewer Orange Line trains but running them with eight cars? WMATA can service the same number of Orange Line riders with one third fewer trains by simply running trains at system capacity.

The current situation is fairly complex. Each Metro line has a capacity of 26 trains per hour (TPH). Right now, the combined Blue/Orange line between Rosslyn and Stadium/Armory is operating at that limit. When the Silver Line starts operating later this month, both the Blue and the Orange lines will see fewer trains to make way for the Silver Line. That much is inevitable.

But the Blue Line reduction is more severe for two primary reasons. First, there's simply more demand for trains coming from north Arlington, so Metro wants to give the majority of the slots to the Orange and Silver lines. The other reason is that the line coming up from Alexandria and southern Arlington splits at Pentagon. Blue and Yellow line riders have two options for getting into downtown. But for the Orange and Silver lines, the only place they can be routed is via Rosslyn.

Many Blue Line riders are understandably upset about having longer waits for a direct train to the western part of downtown. Now, it may often be faster for riders to take the "rush plus" Yellow Line from Franconia and transfer at L'Enfant. But without a separated subway for the Blue Line, there's not much WMATA can do to increase capacity.

Comparing capacity

What does the current breakdown look like?


View peak service levels: Pre-Silver Line   With Silver Line
Note: This graphic was originally created in 2013. Since then, Metro has announced there will be 5 TPH per hour on the Blue Line once Silver opens, rather than 6 as shown here.

Right now at Rosslyn during peak hours, there are 19 inbound Orange Line trains and 7 inbound Blue Line trains each hour. That means there's an inbound train about every 2 and a half minutes.

Of the Orange Line trains, about 40% are 8 cars long and 60% are 6 cars. All of the Blue Line trains are currently 6 car trains. That means that each hour at Rosslyn, there are roughly 42 inbound Blue Line cars and 130 inbound Orange Line cars. This means a total of 172 inbound cars per hour.

Once the Silver Line opens, the distribution will change. Starting on July 28, the mix at Rosslyn will be 11 Orange Line trains each hour, 10 Silver Line trains per hour, and 5 Blue Line trains per hour.

All of the Silver Line trains will be 6 cars in length. The proportion of Orange Line cars is not expected to change, so it will remain about 40% 8-car trains. The Blue Line will operate with half of its trains as 8 car sets.

That means that at Rosslyn, there will be 35 Blue Line cars inbound each hour, a reduction of 7 cars. The Orange Line will also see a reduction, with only 74 cars per hour. The Silver Line will have 60 cars inbound each hour. Now, since the Silver and Orange share in northern Arlington, riders at stations like Clarendon will see 134 inbound cars each hour, which is a very slight increase. Overall, at Rosslyn, that will mean 169 cars inbound each hour (which is a slight decrease).

So, even though the transit agency is reducing Blue Line frequency in order to fit more trains coming from northern Arlington, the change in the length balance of those trains means that essentially passenger capacity is staying the same. It's only increasing by 4 cars per hour. And of course, it's dropping by quite a bit for the stations on the Orange Line west of East Falls Church (from 130 today to 74), though that section of the line is less crowded than the parts closer to the core.

Alternate solutions

Daniel's question is specifically whether WMATA can have the same capacity by increasing the length of Orange Line trains rather than reducing frequency on the Blue Line.

If WMATA kept the same number of Blue Line trains as there are today7 TPH each 6 cars in lengththe inbound Blue would have 42 cars per hour. The number of Orange Line trains would still have to change to accommodate the Silver Line, so let's assume the remaining 19 slots are distributed 10 to the Orange Line, with all 8-car trains, and 9 to the Silver Line, with all 6-car trains.

There would then be 80 inbound Orange Line cars per hour and 64 inbound Silver Line cars per hour, for a total of 144 cars per hour coming through northern Arlington. That would mean a total of 186 cars per hour inbound at Rosslyn, which is significantly more than today.

However, this solution would actually require Metro to use more cars in daily service, and right now, there simply aren't enough. The Silver Line requires more cars to run, since Wiehle Avenue is so far out. The opening of the new line is already stretching Metro's fleet. There will be more wiggle room sometime soon, once the first 64 7000-series cars arrive, but that milestone is probably more than a year away.

The other issue is that Metro still needs upgrade power systems on all the lines to enable more 8-car trains to operate. Right now, even if Metro had enough cars, there isn't enough traction power capacity to run all 8-car trains, though the agency is slowly working to upgrade traction power substations throughout the system.

Metro does anticipate running 100% 8-car trains in the near future. But being able to do so is dependent on being able to finance more 7000 series railcars. Right now, the local jurisdictionswho pay for capital upgradeshaven't ponied up enough money for that to happen, but there's still time.

WMATA expects ridership to continue to grow. More people ride the Orange Line in northern Arlington than ride the Blue Line between Pentagon and Rosslyn, and so the transit agency is trying to send enough trains that way. Officials see a Blue Line reduction as the only way right now, and since the Yellow Line bridge offers a relief valve, Metro can still give Blue Line riders just as many inbound trains each day, but some riders who used to have a direct trip may find themselves making a transfer.

The only way to resolve this capacity crunch is, in the short term, for local governments to fund more railcars and more power stations, and eventually build another Potomac crossing. Without a new river crossing, there can't be more trains on Blue, Orange, and Silver at the same time.

Here are the answers to whichWMATA week 13

On Monday, we posted our thirteenth photo challenge to see how well you know Metro. I took photos of five stations. Here are the answers. How well did you do?

There were 44 guesses on this post. Eight of you got all five correct. Great work FN, Sean Emerson, MZEBE, Peter K, Rob K, JayTee, Roger, and King Terrapin!


Image 1: Fort Totten.

The first image shows the lower level of Fort Totten, viewed from the mezzanine. The lower level of Fort Totten is unique in that it's partially above ground and partially below ground. The northbound train that's visible is emerging from the subterranean portion of the station. 32 of you knew this one.


Image 2: King Street.

The second image shows the north end of the platform at King Street. This entrance is newer than the rest of the station, and is at the end of an extension of the platform. The fences are there because trains don't stop at this section. The roof type (only present at King Street and Braddock Road) and dual elevators are both clues to the station's identity. 26 of you got this one right.


Image 3: Glenmont.

This image shows the bus loop at Glenmont station. This canopy is unique to Glenmont. The Ride On bus you can see at the left was a clue to help narrow down the possibilities. (I specifically waited to take the picture until the bus drove into the frame). 23 of you guessed correctly.


Image 4: Vienna.

The fourth image is a shot of Vienna station from one of the parking garages on the south side of the station. While this station does have the common glass and concrete peaked roof, it is clearly a median station, which narrows it to one of the four Orange Line stations along I-66.

The pedestrian bridges on both sides of the freeway, however, mean that this must be Vienna. West Falls Chruch and Dunn Loring only have a bridge to one side, and East Falls Church has an exit below the platform rather than above. 28 knew that this was Vienna.


Image 5: Rockville.

The final image was somewhat harder. This is a picture of an elevator near Rockville station. This elevator leads from Monroe Street to the pedestrian bridge that takes riders across Route 355 to the station. One clue to the location is the Brutalist Montgomery County Executive Office Building, visible at right. Only 11 of you guessed this one correctly.

Congratulations to the winners!

What are the 10 longest Metro escalators?

Have you ever wondered where your Metro stop ranks in terms of escalator length? Here are the 10 longest escalators in the system.


Graphic by the author.

Each of the escalators shown is actually a bank of 3 escalators (except at Rosslyn, which has 4), so technically this is a list of WMATA's 31 longest escalators.

Metro has 588 total escalators. The longest in the system, in fact the longest in the Western Hemisphere, are at Wheaton, which have a span of 230'. The Wheaton escalators are so long, they're twice the length of Cleveland Park's, which are 10th longest.

Interestingly, 9 of the 10 longest escalators in the system are on the Red Line. Only Rosslyn at number 5 is on a different line.

And while Wheaton's mammoth escalators seem like an almost endless ride, they're only slightly longer than one third the length of an 8-car Metro train.

While Wheaton has the longest escalators in the Western Hemisphere, WMATA's longest are only in 7th place worldwide. The Moscow Metro station at Park Pobedy has the longest in the world, at 413 feet. Stations in St. Petersburg, Kiev, and Prague also have longer escalators than at Wheaton.

Yes, Virginia, here are the answers to whichWMATA week 12

On Monday, we posted our twelfth photo challenge to see how well you know Metro. I took photos of five Virginia stations. Here are the answers. How well did you do?

We only got 26 guesses on this post. Five people got them all right. Congratulations to Justin...., coneyraven, Peter K, Teyo, and Rich F. Great work!


Image 1: Huntington.

The first image shows the view north along the Yellow Line from the southern mezzanine of Huntington. This station is built into a hill, so the southern entrance is above the platform, while the northern entrance is underneath. There's a long sloped glass roof above the escalators here, which is where this view is from. 22 of you knew this one.


Image 2: Rosslyn.

This image was taken in the brand new eastern entrance to Rosslyn station, which is elevator-only. The modern mezzanine matches Metro's architectural style very well, especially the "Arch" stations that were built starting in the mid-1980s.

Several of you guessed Forest Glen, because of the multiple elevators, and while that was a good guess, Forest Glen's bank of elevators is arranged very differently (and was recently featured in Week 10). 19 of you correctly guessed Rosslyn.


Image 3: National Airport.

The third image shows the center track at National Airport station, one of only two stations in the system with this configuration. You can see a bridge across the tracks at the left side of the picture. This was installed while one of the elevators was being renovated. Almost everyone guessed this one correctly. 24 of you got the right answer.


Image 4: Eisenhower Avenue.

The fourth image was a little tricky. This is a shot from the platform at Eisenhower Avenue looking north at the Masonic Memorial. The Masonic tower is close to King Street, but it's easily visible from several stations, including Eisenhower Avenue. The giveaway here is the angle. If we were looking at the front of the tower (as from King Street), we would be able to see its pediment. The other main clue here is the building in the foreground, which is a movie theater. Several commenters recognized it.

Only 14 people correctly guessed Eisenhower Avenue. Eight people took the bait and guessed King Street.


Image 5: Pentagon City.

The final image was taken at Pentagon City. This one proved to be fairly hard. You can easily tell that it's a side platform station, which narrows the field considerably. The "waffle" architecture further narrows it. But the distinctive feature here is the set of knockout panels above the tunnel portal, designed for a future entrance at the south end of the station. Only ten got this one right.
