George H.W. Bush is set to embark on his final tour of Washington, the US capital that is remembering the 41st president's lifetime of public service that began in the navy during the Second World War, ended with one term as the country's leader, and was characterized by what admirers say was his innate decency, generosity and kindness.
Bush is the first president to lie in state since Gerald Ford, following his death in 2006.
College Station is the location of the George H.W. Bush Presidential Library, where Bush will be laid to rest.
Bush was eulogized during a Capitol ceremony by Senate Majority Leader Mitch McConnell, R-Ky., who called him "a humble servant who loved his fellow citizens", and a "principled leader who knew America not only guards our own future, but also safeguards democracy for the world". "So, we look forward to doing that, and he certainly deserves it".
Bush Senior died at on Friday at the age of 94.
He will be honored during several public and private events in Houston and Washington before his burial Thursday in Texas.
Bush was president from 1989 to 1993.
He failed to win a second term after breaking a no-new-taxes pledge. Wednesday has been designated by President Trump as a national day of mourning, and most federal agencies will be closed with federal workers given the day off.
Bush will then lie in repose at St. Martin's Episcopal Church in Houston, where first lady Barbara Bush's funeral was held in April.
The funeral train will include UP No. 4141 George Bush Locomotive, which was unveiled October 18, 2005, during a ceremony near the library and museum on the Texas A&M University campus.
On Wednesday morning, a motorcade will take the remains to a state funeral at the National Cathedral.
The honorary pallbearers in Washington - for both Bush's entry into the Rotunda and the National Cathedral - will be Navy captains and admirals who have commanded the USS George H.W. Bush and members of the carrier strike group.
The picture was posted on Twitter by Bush family spokesman Jim McGrath, along with the caption: "Mission complete".
Sully is named after the airline pilot Chesley "Sully" Sullenberger, who landed a passenger jet on the Hudson River in 2009, saving all 155 passengers and crew on board.
