In Transit

Baseball Transit Authority. We’ll wave you home.

I like baseball. I like stadiums. I like maps. I really like transit. The result: the Baseball Transit Authority!

What baseball fan hasn’t dreamed of single-seat ride between Seattle and Washington, D.C. to catch a Mariners/Nationals doubleheader? The Baseball Transit Authority’s new stadium subway is here to ferry you between ball parks faster than Rickey Henderson could slide into second.

You may notice there are only 25 stations for the 30 MLB teams, with multiple teams combined into single transit stops in Chicago, Los Angeles, New York, Washington, D.C./Baltimore, and San Francisco. Now may be a good time to say: the map is entirely fictional. You can rest assured no fans heading to an Orioles game will be dropped off halfway between Nationals Park and Camden Yards. Best of all, the Baseball Transit Authority system is entirely underground. An original revision did not contain the route between the Twins and Mariners, but fortunately for baseball-transit-fiction-land, Rob Manfred developed some creative financing schemes and was able to complete the entire subterranean Northwest Corridor on-schedule and under-budget.

The Baseball Transit Authority prides itself on performance. While “I don’t care if I never get back” is the chorus of its ridership, this iron rail is more reliable than Cal Ripken, Jr.

Joking about highly-unfeasible transit systems aside, I learned loads about the incredibly-useful vector graphics to produce this map! How can you not be a fan of an infinite-resolution image? Raster graphics (of which JPEG is one format) define images using an array of pixels, whereas vector graphics define images using an XML list of shapes, text, and colors. While you can write the code yourself and understand SVGs (scalar vector graphics) 110% better as a result, fortunately this is not necessary. Cam Booth of the Transit Maps blog recommends the industry-standard Adobe Illustrator to create vector transit maps. For beginners and designers on a budget, Inkscape is a capable alternative. Best of all, it’s free to download! I learned about shapes, grids, paths, and nodes, and was quickly able to apply them to my project of confusing baseball and transit fans everywhere.

Don’t forget: next time you head out to the ball park…

Ride BTA. We’ll wave you home.


  1. very cool – I am sure there are more physical and fiscal obstacles then could ever be overcome. But a very cool fantasy idea.

    Always wanted to spend a whole year traveling the country to every stadium and this would make that a lot easier to do.

    • Alan, I totally agree! I’ve been to 19 of the 30 stadiums, but only get to about 2 a year. You could do it in a month with the BTA! How many have you been to so far?

  2. Expenses not withstanding, it’s possible to get almost everywhere you need to go on a 30-stadium tour by rail. Neat post on the subject here: https://www.reddit.com/r/baseball/comments/3y12ts/offseason_got_a_few_thousand_dollars_and_about/?ref=share&ref_source=link

  3. Great work. Would be neat to see this include all six divisions as train lines. NL east, for example, is complete as-is, but it would be a challenge to get from Boston to Toronto, or Seattle to Houston. I’ll see you on the rails.
