After the funeral at St. Martin's Episcopal Church in Houston, the coffin covered with the US flag of former President Trump "father" was taken to Union Pacific train 4141 in Spring, Texas.
Former President George W. Trump and his family and several others attended the ceremony and then boarded the ship together.
The 41st President of the United States will be buried at the George H.W. Bush Presidential Library and Museum on the campus of Texas A&M University, near the resting place of his wife Barbara and Robin - his grandfather's daughter - who died in 53 at the age of 3.
According to AP, the train was slow to run through some towns on a route of more than 110km. In Magnolia, one of the places where the ship carrying linh Su passed, hundreds of people were present carrying flags to bid farewell.
The AP said that historically, there have been several ships carrying coffins to their final resting place, including the funeral of former US President Dwight D. Eisenhower from the National Church in Washington to his hometown in Abilene, Kansas a few decades ago.
The funeral of former US President George H.W. Bush on December 7 will be attended by family members and a few guests. The ceremony involved the firing of 21 cannons.
CBS quoted Trump's spokesman as saying that traveling to his final resting place by train has been part of the official plan for the funeral of the 41st president of the United States for many years.
