Tramform America

It's time to tramform America.

A train down Main Street is one of the most proven things a town can do to bring back its downtown, keep seniors and teenagers moving, make the school run safer, and help a family out from under a second car payment. Towns of many sizes already run one. Yours can be next.

Main Street · Homes · Safety · Money in your pocket · One track runs through all of it.

You see it every day.

Downtown is half parking lotThe square lost its shops to the bypass, and the lots sit empty six days a week.
Grandma handed in her keysNow every doctor's visit, every church service, every errand needs a ride from someone.
The second car paymentTwo jobs, two cars, two insurance bills. It's the raise the family never gets.
Kids can't go anywhere aloneUntil sixteen, the whole town is a ride away. After sixteen, it's a car you have to buy them.
The hospital moved to the highwaySo did the big employers. If you don't drive, you don't work there and you don't get seen there.
The widening didn't workThey added lanes to the loop. Three years later the traffic is worse and the town has less to show for it.

Why trams

What a tram does to a town

A bus route can be cut in next year's budget. A rail line is a promise set in steel, and everyone plans around a promise: families, shop owners, builders, the bank. That permanence is where the magic comes from.

01 — HOMES

Rails bring roofs.

Builders build where the train goes, because the train will still be there in thirty years. Downtown Plano, Texas was an aging strip of storefronts in the 1990s. The city planned a rail station, builders put apartments beside it before the first train arrived in 2002, and restaurants and a Saturday market followed; there are now more than a thousand homes within a quarter mile of the platform.4 More homes near the station means more homes, full stop, and more homes is how a housing shortage ends.

02 — HEALTH

A healthier daily rhythm.

People who walk to transit log a median of about twenty minutes a day just getting to and from the stop, most of the 150 minutes a week the doctor keeps asking for, built into the trip. Trams are electric, so there's no diesel idling at the curb outside the elementary school, less noise on the block, and cleaner air for the kids waiting at the stop.

03 — SAFETY

Fewer cars, fewer funerals.

About 39,000 Americans died on our roads in 2024, and rural roads carry more than their share: roughly a third of the driving, about 41 percent of the deaths. Mile for mile, riding transit produces about a tenth of the injuries and deaths of riding in a car. A tram runs on fixed rails at predictable speeds, and a street with a tram is a street designed for people. Every household that can leave a car at home is one less car in the school pickup line.

~39,000lives lost on U.S. roads in 2024, by the federal early estimate. That's a packed stadium, every single year.6

04 — MONEY IN YOUR POCKET

The raise you give yourself.

Getting around is the second-biggest bill in the American household, right after the roof. A family that can go from two cars to one keeps most of a car payment, an insurance bill, a gas bill and a repair bill every month. That's the cost-of-living fight, on the one front where a town actually has the power to do something.

$13,000a year is roughly what the American Public Transportation Association figures a household saves by trading one car for transit, averaged across the twenty biggest transit cities. Your town's number will be smaller, and still real.7

And it keeps going

The list doesn't stop there.

Main Street comes back

People on foot stop, browse and spend. A stop on the square can deliver hundreds of them an hour to a shopkeeper's door, with no parking lot required.

Freedom for everyone

Teenagers, grandparents, folks with disabilities, folks who just can't afford a car. Nearly three in ten Americans have no driver's license.13 A tram gives every one of them the town back.

Clean air, quiet streets

Electric from day one, on a grid whose emissions have been falling since 2007.27 No exhaust, no engine roar. Just the bell.

Jobs and tax base

Phoenix counted 35,000 jobs within half a mile of its line in the first decade.2 New buildings can mean new revenue for the schools and the fire department without raising anyone's rate.

One train, 240 cars

A single two-car train is built to carry up to about 400 people, the load of roughly 240 cars, with one operator and no traffic jam.10

Homes worth more, bills worth less

Most studies find homes near a new station gain value: about 4 percent for houses and 11 percent for condos within a mile of Charlotte's line, for example.25 And their owners can spend far less getting around.

Picture it in your town

We're not asking for something new. We're asking for what your grandparents had.

Take a town of sixty thousand on I-35 between Waco and Austin. There's a courthouse square with the good brick buildings, a college on one side, the hospital and the big-box stores out by the highway, and new subdivisions filling in everything between.

Now put a tram down the main road. The square to the college to the hospital to the highway, one line, a train every ten minutes. The college kid gets to a job at the hospital without a car. Grandma gets to the square on Saturday and to church on Sunday without asking anyone. The lots around the stops turn into apartments over shops, and the town collects taxes on buildings instead of asphalt. The second car goes on Marketplace.

None of that is new. Before 1930, a Texas town that size usually had a streetcar, a depot on the square, and a Main Street you could walk end to end. Waco ran electric streetcars from 1891 and an interurban to Dallas until 1948.19 The car didn't replace something that failed. It replaced something that worked, and we've spent seventy years and a lot of money trying to get the same freedom back out of a parking lot.

Common-sense, compact towns are not a European idea. They're the American default. We just stopped building them.

Two ways to spend a few billion dollars

We've tried the other thing. For seventy years.

Houston widened the Katy Freeway to as many as 26 lanes, counting frontage roads. Within a few years, the drive was slower than before.11 That's not a Houston problem; economists find that new freeway lanes fill with new driving almost one for one, from the loop around your town on up.11 Rail is the transportation investment that builds a neighborhood around itself.

The status quo

More lanes, more traffic, less town.

Widenings fill up with new driving within years, flatten the neighborhoods they cut through, and leave nothing you can live in, shop at or walk to.

The tramformed way

A Main Street that builds itself.

Mesa, Arizona ran the train straight down its old downtown Main Street in 2015. Two universities have opened campuses a block from the tracks, one before the line opened and one after, and new businesses have followed.28

A hundred years of the next big thing

What we tried instead.

Every decade since the car arrived, somebody has had a better idea than the streetcar. Here is how those ideas went.

Each one was sold as the thing that would make the train unnecessary. None of them changed the arithmetic: a lane of cars moves something like 600 to 1,600 people an hour, a lane given to transit can move many times that,26 and a town only has so much room between the courthouse and the river. The compact, walkable town was never a European import. It was the American default, and the electric streetcar that built it has been in the catalog since Richmond, Virginia, 1888.23

So when the next miracle comes around, ask what it does for the nurse on the night shift and the widow who can't renew her license. If the answer is nothing, it isn't transportation. It's a demo.

  1. 1920s–50sTowns pulled up the streetcars that had built them. Los Angeles had the largest electric interurban system in the world, more than a thousand miles of track, and lost nearly all of it. A holding company backed by a carmaker, a tire maker and oil companies bought up transit systems in dozens of cities and replaced streetcars with buses; in 1949 a federal jury convicted it and its backers of conspiring to monopolize the sale of buses and supplies to those systems, and acquitted them of conspiring to monopolize transit itself. Historians still argue over how much was conspiracy and how much was policy. The rails came up either way. The interurban from Waco to Dallas ran its last car on New Year's Eve, 1948.19
  2. 1956The Interstates arrived with a bypass for every town. Main Street moved to the exit ramp, and the square got a parking problem.15
  3. 1950s–60sZoning codes across the country began requiring parking with every new building. Downtown blocks came down for surface lots to meet the rule.20
  4. 2003–08Houston widened the Katy Freeway to as many as 26 lanes, counting frontage roads, for about $2.8 billion. By 2014 the commute was slower than it had been in 2011.11
  5. 2013A vacuum-tube train was announced as a cheaper alternative to California's high-speed rail. The rail line is under construction. No tube has ever carried a paying passenger, and the best-funded tube company closed in 2023.21
  6. 2021A tunnel opened under Las Vegas in which cars, each with a driver, carry a few passengers at a time.22
  7. 2026A sports car was hopped into the air at a Texas rocket test site and called a flying car.24

Paying for it

The debt isn't the excuse. It never was.

America built its best things on borrowed money with a plan to pay it back. The national balance sheet is a reason to spend on things that return the money, not a reason to spend it only on lanes that don't.

  1. 1930Golden Gate BridgeVoters in six counties put their homes and farms up as collateral for $35 million of bonds, in the middle of the Depression. Tolls paid the last bond off in 1971.14
  2. 1956The InterstatesPaid, for its first half-century, out of a dedicated trust fund fed by the gas tax. Nearly 49,000 miles of it today; since 2008 the fund has needed about $270 billion in top-ups from general revenue.15
  3. 1962BARTThree Bay Area counties voted a $792 million bond for a railroad that existed only on paper, and rode it ten years later.16
  4. 1983DART, DallasDallas and its suburbs voted a one-cent sales tax on themselves. It built one of the longest light rail networks in the country, about 93 miles, through Plano, Garland, Irving and Carrollton.17
  5. 2004FasTracks, DenverVoters across the metro approved a 0.4-cent sales tax for more than 120 miles of rail. Lines have opened to Arvada, Aurora, Lakewood and the airport; some of the program is still waiting on money.18
  6. Every yearYour townTexas towns vote bonds for high-school stadiums, water plants and highway loops every November. The machinery for this already exists at the county clerk's office.

1. Fares plus a measure

A line pays its running costs from fares and a small, voter-approved sales tax or transit district, the way DART and Denver do. That revenue is what a bond is borrowed against.

2. The land pays for the rails

Stations raise the value of the blocks around them. Tax increment financing captures the growth in that value to repay the bond, without touching the property tax rate. Denver's Union Station was rebuilt that way.12

3. Washington can pay about half

The federal Capital Investment Grants program exists for exactly this. It can fund up to 60 percent of a project and covered about half the cost of the Twin Cities' Green Line.9 Projects under about $400 million go through the simpler "Small Starts" track, which is where most town-sized lines would land.

The honest part: a bond is a loan, and a loan needs income behind it. That's why the ask is never "build a train." It's "put a train and the half-cent that runs it on the same ballot." Towns that do both get the line. Towns that only vote for the first half get a study.

At the microphone

Six things you'll hear at the council meeting.

And what to say back, short enough to fit in your three minutes.

They'll say: "My property tax rate will go up."

It doesn't have to. With tax increment financing, the rate stays where it is. The line is paid for out of the growth in value it creates along the corridor, growth that wouldn't exist without it. Denver used it to rebuild Union Station and pay the loans back early.12

On top of that, the federal Capital Investment Grants program covered about half the cost of the Twin Cities' Green Line, and can go up to 60 percent.9

They'll say: "Nobody will ride it."

People ride what's frequent and goes where they're going. Phoenix, a place built around the car, went from zero to more than 50,000 riders a day within its first decade.2 Lines fail when they're slow, short and infrequent, and succeed when towns give them their own lane, priority at the lights and a train every ten minutes or better. That's what we advocate for: light rail done right.

They'll say: "Just run more buses. They're cheaper."

We should run more buses too. But a bus route can disappear in a single budget cycle, so nobody builds apartments next to one. A tram is permanent, and permanence is what unlocks the homes, the shops and the tax base. A two-car train also carries several buses' worth of riders with one operator,10 so on the busiest road through town the cost per rider can fall.

They'll say: "We're too small and too spread out for a train."

Kenosha, Wisconsin has a streetcar and about a hundred thousand people.29 Little Rock, Tempe, Tucson and El Paso run them. Phoenix, Dallas, Houston, Denver and Salt Lake City were built around the car, and every one runs light rail through suburbs that look like your town. The tram doesn't need density to exist. It can create density, one stop at a time, where the town wants it.

They'll say: "It's too expensive."

Compared to what? A single highway interchange now runs into the hundreds of millions of dollars,30 generates no development, and fills up again within years.11 Phoenix has spent about $4 billion on its system and counted $20 billion in new building beside it.2 The Twin Cities spent under $1 billion on the Green Line and counted almost $6 billion built along it.9 Ask the people who say it's too expensive what the loop road returned.

They'll say: "Streetcars flopped in other towns."

Some did, and for predictable reasons: a short loop, stuck in car traffic, a train every twenty minutes. A tram that's slower than walking is a tourist ride, not transit. The fix is known and boring: its own lane, priority at the lights, real frequency, and a route that connects where people live to where they work and shop. Build it like that and it fills up.

Already tramformed

This isn't a big-city thing.

Kenosha, Little Rock, El Paso, Plano, Norfolk, Tempe, Tucson: dozens of American towns and suburbs run light rail or a modern streetcar today. Hover to pause.

Your town

Every line started with a few stubborn neighbors.

Nobody at city hall will propose this for you. Here is how ordinary residents get a light rail line onto the agenda, and keep it there.

  1. Find five neighbors

    Movements start at kitchen tables, not conferences. Send this page to five people who complain about the loop, rent or their car payment. Start a group chat. Pick a name. "Tramform Temple" has a ring to it.

  2. Show up and speak

    Council and transit board meetings are mostly empty. Three minutes at the microphone from a resident with numbers beats a hundred consultant slides. Use the objections section as your script.

  3. Ask for the study

    Every line begins as an alternatives analysis. Ask your council to fund one, and ask your regional planning organization to put a rail corridor in the long-range plan. Paper first, then steel.

  4. Back candidates who back rail

    Local races are often decided by a few hundred votes. Somebody could run for county office with a light rail line as their first issue and explain plainly how it gets paid for without raising the property tax rate. Find that candidate in your town, or be them.

Get inspired

Watch these. Then send them to someone.

Two videos that make the case better than we can. They'll work on your skeptical uncle, too.
