Boris Johnson and Joe Biden bonded over their shared love of trains in the first call between the leaders, discussing how green energy and climate change would be a “number one priority” for both countries.
The Prime Minister, who is believed to be Mr Biden’s first call to a foreign leader outside of the Americas, asked the US president about his Amtrak train journeys across the country, a source familiar with the conversation told The Telegraph.
After Mr Biden’s wife and daughter died in a car crash in 1972, the then senator rode on Amtrak every day from his home in the state of Delaware to work in Washington DC. His plan to travel by train to his inauguration earlier this week was scuppered by security concerns.
The president has often talked about his passion for trains and lobbied in the Senate for more public funding for the rail sector, earning him the nickname “Amtrak Joe”.
Mr Biden lamented that he will not be able to take the train, which he has called his “favourite means of transport”, as much as he used to in his new White House role.
Mr Johnson, who has previously revealed he has a hobby of making model buses, last November announced plans for a “green industrial revolution.” Goals include ending sales of gas and diesel cars by 2030, promoting public transport, cycling and walking and achieving net zero carbon emissions by 2050.
