Posts about Purple Line
According to the latest plans for Maryland's Purple Line, it will have the longest transit railcars in America. Each train will have a single 136-foot-long five-segment railcar. They'll practically be open-gangway trains.
At 136 feet long, they'll be 2 feet longer than the closest US competitor: Austin Metrorail's 134 foot cars. But Austin's cars are DMUs, a sort of commuter rail / light rail hybrid, built for longer distance and fewer stops compared to the Purple Line.
The next biggest US light rail cars are Dallas' 124 foot cars.

Longer is better
Having one long railcar rather than multiple short ones has a lot of advantages. There's less wasted space between cars, less expense per rider, and passengers can move back and forth inside the train to find the least crowded spot. Overall, having one long open interior increases the capacity of a train by about 10%, and it costs less.
The downside is you can't pull individual cars out of service if something goes wrong. It's all or nothing. But as long as everything works, long railcars are great.
Since the Purple Line will be operated by a private company that faces penalties if it doesn't meet service requirements, the onus is on them to keep trains in service.
In transit jargon, these open interior trains are called "open gangway," and almost everyone else in the world uses them, except the United States. For the Purple Line to move in that direction makes it a national model.
Using these long trains was one of the changes project officials made in response to Maryland Governor Hogan's demands to reduce the Purple Line's costs. One long railcar rather than two short ones coupled into a train saves money and keeps train capacity high enough to work.
Hogan's other changes made the Purple Line a lot worse. They reduced train frequency, eliminated the direct transfer to Metro at Silver Spring, and reduced the electrical power of the line, limiting its capacity. But the move to longer railcars with open interiors may be a silver lining.

The winning bidders for the Purple Line project, Purple Line Transit Partners, proposed a few changes that would save the state of Maryland money. One of those changes is to relocate the Silver Spring Purple Line platforms farther away from the Metro.
In the original plan, the Purple Line platform was going to be in a a new elevated structure between the existing Silver Spring Metro station and the new Silver Spring Transit Center. The new plan moves the Purple Line platform to the other side of the transit center, closer to the intersection of Colesville Road and Wayne Avenue.
This design means that people going between the Purple Line and the Red Line will have a longer walk. However, the new platform will now be level with the top floor of the transit center, giving people a shorter walk to buses, taxis, and the kiss-and-ride. It's also slightly closer to the heart of downtown Silver Spring.
Moving the Purple Line station also consumes a lot of land next to the transit center that was originally set aside for development, though those plans have since fallen through. But the change makes it unnecessary to demolish one building, 1110 Bonifant Street, which the original plan required.
This design includes a large bridge over Colesville Road. As planned all along, the Purple Line will rise over the existing Red Line tracks, the Silver Spring Transit Center, and the large hill behind the transit center, before coming down to ground level near the intersection of Bonifant Street and Ramsey Avenue. At some places, the tracks will be over 60 feet high.
This plan is part of a large report PLTP submitted to Governor Hogan, which includes drawings, maps, and even renderings of potential Purple Line vehicles. In the coming months, the state will work with PLTP to create a final design for the Purple Line. Construction is scheduled to start later this year and the line could open in 2022.
After more than a year of uncertainty and delay, Maryland has selected a firm to build and operate the Purple Line. With Purple Line Transit Partners in place to run the 16-mile line, the project is ready to move forward.

After Marylanders elected Governor Larry Hogan in November 2014, it wasn't clear whether the long-planned light-rail line would even happen. But following a prolonged public show of support, Hogan announced that the Purple Line would get built if Montgomery and Prince George's Counties committed more funds and trains ran less frequently.
Four teams submitted bids in December, and Maryland selected Purple Line Transit Partners. Some have questioned the bidder's plan to purchase railcars from a company that made some of Metro's least reliable cars and has been plagued with delays in other cities.
Update: After a series of state and federal approvals, construction should start late this year for a planned opening date in spring 2022.
In Maryland, the governor has a lot of unilateral authority to kill or approve transportation projects, and Larry Hogan hasn't been slow to wield it. But Maryland legislators are working to pass a law that'd make it harder to cancel projects that'd benefit the community at large.

Maryland Governor Larry Hogan campaigned on redirecting more money from transit to roads. And when he came in, he started doing just that, removing large amounts of state aid from the Purple Line and totally killing Baltimore's plan for a light rail system.
Last Tuesday, Maryland lawmakers unveiled a slew of bills aimed at bringing balance back to the transportation budget. One, called the Open Transportation Decision Investment Act (SB908/HB1013), could change the way Maryland funds transportation projects.
This particular law would establish a scoring system that considered transportation projects in the context of measures like environmental stewardship, community vitality, economic prosperity, and equitable access to transportation. If a Governor decided to fund a project that ranked low over one that ranked high, he or she would have to provide an official explanation.
It's been hard to stop Hogan from going after transit projects
In Larry Hogan's first year, state construction aid for the Purple Line went from $700 million to $168 million, and both Montgomery County and Prince George's County had to cough up more money to keep it alive. Highways went from making up 45% of the transportation budget to 57%.
Hogan is now using the Maryland Transportation Trust Fund to build highways and support sprawl, the exact opposite of what the fund was intended to do.
Regarding the Baltimore Red Line, Hogan called the project a "wasteful boondoggle." Killing it, however, was a major blow to Baltimore leaders and business interests. Research pointed toward the line having huge economic benefits, with 15,000 jobs coming from project construction alone.
Cancelling the Red Line is an even bigger blow to Baltimore when you consider sprawl is a major economic drain on the city's economy.
Where did the savings killing the Red Line go? You guessed it: roads.
Of $2 billion dollars in road projects($1.35 billion of it new), most went to sprawl-inducing development like $160 million dollars to widen Route 404 on the Eastern Shore and $90 million to realign a road in Garrett County.
This bill could keep officials like Hogan in check
While Hogan's spokesperson called SB908/HB1013 a "power grab," Virginia enacted a similar bill with bi-partisan support.
So is this really a partisan issue? No. What this bill does is prevent killing or approving projects arbitrarily. It makes it so that merit, not ideology, is what decides whether projects move forward.
Hopefully with more transparency, pro-sprawl governors like Larry Hogan will have to explain to taxpayers why they are spending millions of dollars on projects that just do not add up.

With the Purple Line's future looking brighter, it is finally becoming easier to envision the embattled light rail line becoming a reality. But if the line does become a part of our region's transit network, will it also be a part of the iconic Metro map?

While it's called the "Purple Line," WMATA would not be building this line, nor was it planned as a part of the Metrorail system. It's still unclear how well the line would integrate with other lines. There hasn't ever been a decision made about whether, for example, you'll pay a separate fare to ride the Purple Line, as with a bus, or whether it will be part of the same fare structure as all of the rail lines.
Advocates and planners have long shown images of the Purple Line on Metro map to help cement the idea that this new line will become a critical component of the region's rail transit. But it isn't trivial to fit the line into the existing Metro map.
How can the Purple Line fit?
If it appears on the map, the Purple Line would be the just the second line color to go on the map since the system's inception, besides the Silver Line. Unlike the Silver, though, the Purple Line and its winding route among the branches of the Metro system will force significant changes to fit with the map's chunky, iconic style.
The map's diagrammatic nature distorts the system heavily as the lines spread outside the core. Simply adding the line itself in and making minor modifications to label placement actually works fairly well, but it's tough to squeeze 10 Purple Line stations into the space between Silver Spring and College Park, while there are only three between Silver Spring and Bethesda.
People might assume, from the above map, that the stations east of Silver Spring are very close together, and very far apart to the west. But that's not true. Instead, the two branches of the Red Line are much closer together than the map suggests.
One solution is to shift the Green/Rush Yellow segment north of Fort Totten to the east. While this more accurately reflects the route through Prince George's County, the change would be one of the most significant to the map since its creation in the 1970s, and may perhaps be a controversial one.
Should the Purple Line get equal billing to heavy rail lines?
The Purple Line is not a Metrorail line. It is a light rail line. And WMATA will not even operate it. Arguably, therefore, the Purple Line should appear less important than the six Metrorail lines.
Today's map doesn't even show other rail services like Amtrak, MARC and VRE. They only get logos next to their respective transfer points. But far more people will likely transfer to and from the Purple Line, and it will run much more frequently than commuter rail or Amtrak. Just using icons would not make the Purple Line very visible. On smaller printed or web versions of the map, they may be difficult to spot at all.
The map could display the Purple Line but in a different style. A thinner line, using smaller station labels, or only showing the line itself and not the stations are all possible solutions.
