Mapping the derelict lines of the Bay Area

The old railroads that once defined the Bay Area and the country at large are typically just hinted at. Some lines only operate freight; others, overgrown rails, but many are just sinewy lines on a parcel map. While we do have old maps showing where the rails were, these are rail maps, not service maps.

Some years ago, I used old timetables to create a service map of Marin’s Northwestern Pacific Interurban, which brought to life a system that has been gone for over 70 years. This year, I decided to do the same thing for the whole of the Bay Area, and I’m launching a Kickstarter to fund prints and maps of other regions of the country.

The first map, for the Bay Area, shows every train published in the 1937 Official Guide to the Railways that began within the 9-county Bay Area. After lines leave the Bay Area, the map shows their last convergence points before major hubs like Los Angeles. If you want a print, head on over to the Kickstarter page.

The maps makes clear how much of a legacy these old rail companies left to the region. BART’s southern East Bay lines largely follow the Western Pacific right-of-way, while Amtrak still follows the Southern Pacific, including the A5/A6 route to San Jose. The map also shows some of the oddities leftover from competition, like the parallel Amtrak and BART lines, sometimes just a few blocks from one another.

To the north, BART’s Bay Point line follows the Sacramento North, while its route to Richmond blends ATSF and Southern Pacific rights-of-way. Caltrain still runs on Southern Pacific track, as does ACE.

I don’t think anything runs on the dinky little Bay Point & Clayton right-of-way, which itself is a fun story.

If you like railroads, and you like cool maps, then you really will want to sponsor. Seriously, $40 is pretty good for a 24×24 poster.

I also have prints of my map of Marin’s Northwestern Pacific Interurban. Next up is the Washington-Baltimore region. I’m not sure what’s next, but I’m really excited to see what comes out of the mist.

A new 101 bus map for a revised bus system

In case you missed it, Marin Transit, in partnership with Golden Gate Transit, has made some changes to Marin’s bus system. The changes to existing routes saved enough money that they were able to add about 15,000 more service-hours to the system, meaning people around the county have better transit.

The changes inspired a second look at my 101 corridor bus guide, and the result is here.

While the guide, technically called a “strip map,” reflects the changes to bus routes, I’ve also added non-GGT and Marin Transit routes to the map. Greyhound’s once-per-day north-south Arcata-SF service, Sonoma County Transit’s express services, and Mendocino Transit Authority’s service from Fort Bragg to Santa Rosa all made it onto the map.

It’s much less Marin-centric as a result, but no detail has been lost. Instead, Sonomans can know their options, Marinites can know their options, and all users get an expansive view of where they can go by transit in the North Bay’s 101 corridor.

This is the sort of map GGT needs to have at every bus pad and every transit center along its route. I created the original 101 bus map because I couldn’t visualize how all the lines interact and work together, nor could I tell what buses served which bus pad.

My home church, for example, is located off Smith Ranch Road, so it’s off the Lucas Valley bus pad. Since the 49 is the only bus whose schedule said it stopped at Lucas Valley, I’ll probably take it, turning what should have been a 15 minute ride into a 35 minute tour of Terra Linda.

With this map, I know I can have take the 70, 71, or 80. On a weekday evening, I might take the 44. But the 49? While it does serve the bus pad, it’s a local bus serving Terra Linda and the Civic Center, so it’s not the best idea.

A pocket version will be available in the next few weeks.

Personalized mapping

Transit maps in Marin are, well, not very good. Especially for the uninitiated, they can be confusing spaghetti.

About a year ago, I was contacted by a young man in Novato who had his drivers’ license suspended for some reason and wanted to know how to get around to his destinations. He went to school in College of Marin, worked in Petaluma, and hung out with his friends in the East Bay. How was he supposed to get out of Novato without a car?

After an abortive attempt at a Novato spider map, I realized all I needed were the various connections between the destinations so he could know exactly how he could get from A to B without all the mess of geography. The map below is the result.

It’s simple, so it doesn’t include things like frequency or span of service. Instead, I wanted to show how to get from place to place, major stops, and where those routes went after transfer points and destinations, without all the fuss of a more detailed map. Were I to make this again, I would probably place 49/49K to the west of the 101 corridor north of Ignacio and east of it to the south to reflect actual geography, but as it stands I think there’s enough hints for the user to see where the bus goes.

I’ve never followed up with him to see how it went, though he seemed pretty excited to see it. Perhaps it will be of some use to you as well, as it’s now up in the Map Room.

The 101 Bus Pocket Guide

By popular demand, I’ve reworked the Highway 101 Strip Map into a printable version and added a timetable. Print this out and stick in on your wall, shove it in your (man) purse, or gloat to friends that you actually know where you’re going. Because you deserve it. If you’re a bus driver, defy your superiors and put this on display where passengers can see it when doing a 101 run. Seriously, they’ll thank you.

Guides like this one are extremely useful for complicated, but important, pieces of transit infrastructure. How all the routes come together to form a single bus system from top to bottom is what makes 101 the trunk line that it is. Leaving it unmapped, as GGT and Marin Transit have done, simply hides from the public how much transit is actually available to use.

Alternative Future: A Contemporary Interurban

Click to enlarge, or click here for PDF. This map assumes other lines are operating around the Bay Area, but that map will have to wait for another time.

Let’s say for a minute the Interurban hadn’t stopped running in 1941. It was bleeding money, but its parent company, NWP, was a for-profit entity. What if the Interurban had somehow survived?

For the sake of this exercise, I’m taking a few liberties. First, that the Bay Area had valued its rail transportation system from the 30s to the present, but had consolidated it all, as well as the Golden Gate Bridge, under the single umbrella of the MTC. Second, that European best practices had been implemented at least in this corner of the country. Third, that the Interurban could now survive on a 50% subsidy. And fourth, that Marin and Sonoma have their current populations, though with less sprawl.

Though I had originally intended for this to be a bit more a light post rather than something more data-driven, a Twitter conversation with Dan Lyke motivated me to put some numbers behind the costs of an Interurban.

Costs per vehicle-kilometer (vkm) vary widely based on the system. Vancouver’s automated Skytrain system costs $2.18/vkm, BART costs around $3.50/vkm, and New York’s subway costs $5.81/vkm. Using quite a few assumptions, I get an average annual operating cost between $43.2 million and $111.6 million. If we assume an average fare of $2.50 and a 50% farebox recovery rate, total ridership would need to be between 8.6 million per year, roughly the same number of transit trips on today’s GGT system, and 22.3 million. With the Geary and North Beach extensions (Muni’s 38-Geary alone carries over 13 million weekday passengers per year), it’s entirely feasible for the system to meet BART’s 80% farebox recovery.

Alas, reconstructing the system would be prohibitively expensive and politically impossible. Large portions of some major roads (Sir Francis Drake Boulevard, Fourth and Third Streets, Magnolia Avenue, Miller Avenue, and others) would need to be converted back to rail, wealthy homeowners would need to accept trains running behind their back yards, Sausalito would need to take a new elevated railway along the waterfront, Geary and North Beach would need to be torn up for a new subway, and over $10 billion would need to be spent. While the San Francisco part of the project might be worth it, for 8 million riders per year, most of them already served by transit, the cost and pain of the Marin Interurban simply wouldn’t be worth it.

This map, along with all my other maps, is posted in the Map Room.

Mapping the Interurban

In 1941, the last ferry and the last train ran on the NWP Interurban commuter line, and Marin was handed over to the battle of its life against the car-centric development unleashed by the Golden Gate Bridge. Marinites, unlike most of the country, won that battle, and we maintained the transit-oriented development passed down from the age of rail.

Most of us, though, don’t even know what it looked like, and the best thing we’ve got are grainy maps and schedules from the 1930s. That’s all well and good, but hides the structure and sinews of the system. The purpose of contemporary transit mapping is to combine not just where a system goes, but how and, to a lesser extent, when.

I’ve created two maps that do just that for the Interurban. The first is in an “old” style. Old printing techniques could only print two or three colors. Given that the Interurban shut down in 1941, I thought a map inspired by that era made sense.

One color does make it hard to tell apart individual lines. Click to enlarge.

The second map is the same thing, but in a “new” style. With contemporary printing techniques, we can do as many colors as we like. The advantage is that individual lines can be individually colored, snapping into focus what lines go where.

The colorful lines really make service stand out. Click to enlarge.

As you can see, it was quite a comprehensive system, at least for Central and Southern Marin. Northern Marin was served by intercity rail, more akin to Amtrak than BART, and was not part of the electric rail system highlighted here.

New Visual of Highway 101 Service

Marin’s bus service is centered around Highway 101 and its “trunk” routes. From commuter lines to the basic San Francisco regional lines to the supplementary local routes, getting from one place to another on Highway 101 should be an easy task. Alas, it is not.

Not every bus pad is labeled on the freeway bus map with which buses stop where. Since not all buses stop at all bus pads, you don’t always know whether to take the bus or not. The first time I went by bus to the Lucas Valley pad on a Sunday morning, I tried to figure out which buses stopped there and would pick me up at the Transit Center. Not knowing that it was all printed in the front of my transit guide, I took the 49K and went on a long, 35-minute ride around Terra Linda. Had all the information been in front of me at once on a simple map, I would’ve known that the 70 and 80 would’ve taken me, no problem, but that I should avoid the 101.

The bus map here is a strip map, a simplified diagram showing all stops and which buses stop and which stop when. Though it’s a design that could be improved upon, the map does show all routes and all stops along the 101 corridor. Ideally, the map would be paired with a Highway 101 timetable showing all bus departures. It and the schedule would be posted at every bus pad and major transit hub on the corridor, allowing every passenger to know which bus goes where.

At 41 inches long but only 10 inches wide, it could also be posted inside buses that run along the 101 corridor, allowing passengers to look at it and internalize it while riding, like how subway cars have a map of the subway posted.

Since this is a rather complicated trunk line, be sure to post corrections and comments for me. How, too, could this design be improved upon? What might make this a less confusing or more useful diagram?

On another topic, be sure to come out this Wednesday to the Flatiron, 724 B Street, San Rafael, CA, at 6pm for our third happy hour. It’ll be good times, I guarantee it.

UPDATE: I neglected to mention that Anthony Nachor of My Bay Area Ideas was instrumental in proofing things. He knows the 101 system like the back of his hand, so a hat tip to him for his help.
