Before Air Force One, US presidents traveled aboard a luxury train car. See inside the ‘White House on wheels.’

On December 18, 1942, the Pullman Company presented a luxury train car — originally built in 1928 — that had been rebuilt at the request of the US Secret Service, which had determined that the president needed a secure way to travel during wartime.

Roosevelt most often used the car to travel from Washington, DC, to his home in Hyde Park, New York. The president insisted on not surpassing a speed of 35 miles per hour when traveling aboard the Ferdinand Magellan, making his journeys less efficient and heightening security measures, per the White House Historical Association website.

He last rode the car on March 30, 1945, when he visited his Little White House in Warm Springs, Georgia, where he died a few weeks later.

During his time, the president rode over 50,000 miles aboard the presidential train car.

While the car was rebuilt with Roosevelt in mind, including certain designs that would allow him to use a wheelchair on the train, it was his successor, President Harry S. Truman, who used it the most.

The president, who, unlike Roosevelt, opted for a speed of 80 miles per hour, employed the car in his iconic 35-day whistle-stop tour during his reelection campaign in 1948, where he delivered 356 speeches from the back of the Magellan, per Architectural Digest.

By the time Truman’s successor, President Dwight D. Eisenhower, took office, more efficient air travel was starting to replace rail travel, and the US Car No. 1 was used for the last time in 1954.

In 1984, Reagan brought the Magellan out of retirement for a one-day whistle-stop tour through Ohio during his reelection campaign.

The president traveled from Dayton to Perrysburg and stopped at five locations to give speeches from the rear platform of the presidential car.

In 1959, the Gold Coast Railroad Museum in Miami, Florida, acquired the car, which in 1958 had been declared surplus and donated to the Smithsonian, which had no way to store it.

Since then, the car has stayed in South Florida, where it is now open to the public.

The Gold Coast Railroad Museum is open Wednesday through Sunday from 11 a.m. to 4 p.m. on weekdays and from 10 a.m. to 4 p.m. on weekends. A regular adult ticket for the museum costs $12, and tickets for the presidential train car cost an additional $10.

The car, which is 84 feet long, 10 feet wide, and 15 feet tall, was covered with over 1/2 an inch of nickel-steel armor on its sides and featured 3-inch-thick bulletproof glass windows.

It was also the heaviest passenger train car built in the US. After it was refurbished for presidential use, the train car weighed 285,000 pounds, making it much heavier than modern-day war tanks, which often weigh around 100,000 pounds.

The car also had its name, Ferdinand Magellan, removed from its sides in an effort to conceal the president’s presence, although its design often stood out.

Other security features included two escape hatches and a complex security protocol, which included diverting traffic on the rails to ensure that no train traveled ahead or behind the president for at least 30 minutes. Operating under the code name POTUS, the president’s train always had the right of way.

The entrance through which presidents and their guests would’ve entered is at the front of the car.

The train’s dedicated chef prepared the president and guests’ meals inside this kitchen.

The kitchen was also equipped with a pantry and a full-size metal sink.

Near the kitchen, the two-person staff had sleeping quarters that featured an upper and lower berth.

The presidential car’s main cabin featured a 6-foot solid mahogany table where the president and his guests — often diplomats or foreign leaders — could gather for dinners or meetings.

Presidents and guests didn’t have to sacrifice the White House‘s luxuries while they were on the move — the dining room had its own set of china decorated with the presidential emblem.

The 3-inch-thick laminated bulletproof glass windows were installed when the car was refurbished for the president’s use.

The windows were sealed, so to keep the car ventilated there was a simple form of air conditioning in which fans pushed air cooled by blocks of ice.

The first of two guest bedrooms aboard the US Car No. 1, Stateroom D, included an upper and lower berth, where guests could sleep, and an in-room bathroom.

In these guest rooms, Truman welcomed British Prime Minister Winston Churchill during his visit to the US in 1946, during which he delivered his iconic Iron Curtain speech.

Designed to accommodate Franklin D. Roosevelt’s wheelchair, the president’s room included a full-size bed, a dresser, and an in-room toilet.

Like most rooms in the car, it was also connected to a telephone, which was extremely rare at the time.

The presidential suite bathroom, equipped with a bathtub, toilet, and sink, connected the president’s and the first lady‘s rooms, staterooms B and C.

The bathroom also contained an escape hatch, which was added as a security measure during the car’s refurbishing.

Inside the first lady’s quarters was a bed and a dresser, although she didn’t have an in-room bathroom.

Located towards the back of the car, Stateroom A, the second guest room aboard the Magellan, featured convertible berths, like the other guest room, that could also be used as a breakfast, gathering, or office space for the president or his guests.

The upper berth could be raised into the ceiling, and the lower one could be converted into a sitting booth with a pull-out table.

The Ferdinand Magellan functioned as a White House on wheels, and was often attached to train cars dedicated to Secret Service, White House staffers, and reporters traveling with the president.

The US Car No. 1 was also often accompanied by two communications cars equipped with control consoles for radio broadcasts and telegraph communications so the president could be reached while he was on the move, per Atlas Obscura.

A slim, wood-paneled hallway led from the four staterooms to the observation deck at the rear of the car.

The observation room was also enlarged during the refurbishing of the car, allowing it to function as a secondary gathering room for the president and his guests.

Part of the car’s security modifications included the addition of escape hatches, like this submarine hatch on the observation lounge.

In 1992, Hurricane Andrew hit South Florida, and among its many damages were some sustained by the Magellan.

Although minor, a small window crack shows how the presidential car has stood the test of time.

At the end of the presidential car was an exposed podium from where the president often addressed crowds.

During Truman’s whistle-stop tour, he spoke from the podium repeatedly, often addressing crowds in different cities within the same day.

Inactive as the president’s main form of transportation for over 70 years, the Ferdinand Magellan stands as a memory of America’s past.

However, our tour guide pointed out that the car is still on a track connected to current-day railroads and can be requested for use at any moment by the sitting US president.

Although I doubt Donald Trump would want to travel aboard the historic cabin, a modern-day president going on his own whistle-stop tour on US Car No. 1 remains a possibility.
