We had an all-encompassing view of Rio de Janeiro and its surroundings: Sugarloaf Mountain, the Christ the Redeemer statue, Copacabana Beach. Architectural novelties like the Niterói Contemporary Art Museum and the Metropolitan Cathedral stood out among the sea of buildings, as trains and streetcars passed by, and thousands of dancers swayed and strutted during the city’s Carnival celebration.

Yet Rio was more than 6,000 miles away, while my husband, son and I stood in a building in the Speicherstadt, the historic warehouse district in Hamburg, Germany.

The scene we admired is one of more than a dozen sprawling exhibits at Miniatur Wunderland, home to the world’s largest model railway and largest miniature airport. The meticulous replica of Rio came on line as Wunderland’s newest exhibit in December 2021, constructed over four years in partnership with a family-owned model-making company out of Argentina.

“Mind-blowing,” my husband said several times during our five hours of marveling at reproductions of Germany, Italy, Scandinavia, the United States and other sites, complete with tiny hand-painted figures participating in the myriad activities of daily life. Through all of the landscapes, trains continually chugged along a total of 16,138 meters (almost 53,000 feet) of track.

The project started in 2000 when the twin brothers Frederik and Gerrit Braun, then 32, dreamed of creating the largest model railroad in the world. The siblings, who grew up as train buffs, wound up running a Hamburg nightclub and record label in the 1990s, but eventually they wanted a lifestyle change. With help from friends and family, the Brauns opened Miniatur Wunderland’s life-size doors in 2001.

In the 21 years since, the attraction has drawn more than 21 million visitors from around the world, becoming one of Germany’s top tourist draws. Yet in the United States, Miniatur Wunderland is primarily known among railroad buffs and other hobbyists.

Count us lucky to have a son, now 15, who has been obsessed with planes, trains, cars and anything else that moves mechanically since he was old enough to point. Lucky because I hadn’t known about Miniatur Wunderland, despite having made numerous trips to Germany, as the daughter of two German-born parents. My son, on the other hand, had been talking about Wunderland for years, ever since he discovered some YouTube videos of it. He was particularly interested in the working airport, which averages 500 takeoffs and landings a day, displayed on a flight monitor (the difference: these model planes are always on time).

So when we planned a trip back to Germany in August to see family in Munich, we added a detour to Hamburg to visit Miniatur Wunderland (and bought tickets online a month in advance for the timed entry). My husband and I wanted to indulge our son, an only child, but what we didn’t anticipate was our own enchantment with this tiny world, full of painstaking detail and technological wizardry, sure, but also bursting with whimsy and humor.

Take the diorama of Italy, for instance. Among the faithful reproductions of St. Peter’s Basilica, the Colosseum and Mount Vesuvius (complete with regular eruptions), there are little moving vignettes, activated by pressing a button (200 such buttons exist throughout Wunderland). In one, Pinocchio’s nose grows six inches across the room of a tiny cottage. Elsewhere, a small Michelangelo bounces on a trampoline to reach the Sistine Chapel ceiling with his paintbrush. Creative license? Absolutely.

“That was the model builder saying, ‘I could have put Michelangelo on scaffolding, but nobody would see it. What could I use instead to show him painting?’” said Thomas Cerny, a software developer and spokesman for Miniatur Wunderland, in a recent phone interview. “The model builders are what make the whole exhibition special. If you know them, you can even tell who built what, as each one has their own sense of humor,” Mr. Cerny added, while sharing with a chuckle that the 100 or so statues of saints on the colonnades in St. Peter’s Square wear clothing made of paper napkins from the Wunderland bistro.

As we moved from exhibit to exhibit, directing each other this way and that to point out some new captivating feature, we appreciated that the landscapes were anything but static. In addition to the trains, cars and boats that travel about (in the Scandinavia section, ships navigate tides in real water), most of the almost inch-high figures are doing something, animated in their depiction if not through actual movement. “As time went on, the model railway became less important, and the storytelling and the creativity became much more important,” Mr. Cerny said.

On the fourth floor, we passed by the central command for all of the exhibits, filled with large screens and electronics. It was like an open kitchen. Not only do the systems that control the trains, vehicles and lighting originate here, but video cameras let staffers monitor things like train derailments and other glitches that can occur with so many moving parts.

We discovered that it’s not always sunny in Miniatur Wunderland, either. Every 12 minutes, the exhibits shift from day to a three-minute-long night, and the real rooms darken as almost half a million LED lights twinkle within the dioramas. Each of those lights is programmed to turn on in sequence rather than all at once, creating a condensed simulation of nightfall. “The brothers are perfectionists,” Mr. Cerny said of the founders.

What the Shell: Scientists Marvel as NZ Snail Lays Egg from Neck

What the Shell: Scientists Marvel as NZ Snail Lays Egg from Neck

A rare New Zealand snail has been filmed for the first time squeezing an egg from its neck, delighting scientists trying to save the critically endangered meat-eating mollusk.

Threatened by coal mining in New Zealand's South Island, a small population of the Mount Augustus snail was transplanted from its forest habitat almost 20 years ago to live in chilled containers tended by humans.

Little is known about the reproduction of the shellbound critters, which can grow so large that New Zealand's conservation department calls them "giants of the snail world".

A conservation ranger said she was gobsmacked to witness a captive snail laying an egg from its neck -- a reproductive act well documented in other land snails but never filmed for this species.

"It's remarkable that in all the time we've spent caring for the snails, this is the first time we've seen one lay an egg," conservation ranger Lisa Flanagan said this week.

"We caught the action when we were weighing the snail. We turned it over to be weighed and saw the egg just starting to emerge from the snail."

Conservation department scientist Kath Walker said hard shells made it difficult to mate -- so some snails instead evolved a special "genital pore" under their head.

The Mount Augustus snail "only needs to peek out of its shell to do the business," she said.

The long-lived snails can grow to the size of a golf ball and their eggs can take more than a year to hatch.

They eat earthworms, according to New Zealand's conservation department, which they slurp up "like we eat spaghetti".

Conservation efforts suffered a drastic setback in 2011, when a faulty temperature gauge froze 800 Mount Augustus snails to death inside their climate-controlled containers.

Fewer than 2,000 snails currently live in captivity, while small populations have been re-established in the New Zealand wild.
