US senators are attempting to ban presidents and their families from investing in and promoting cryptocurrency, calling it a "profoundly corrupt scheme".
Eighteen-year-olds will be allowed to drive trains due to concerns over labour shortages, the Department for Transport (DfT) has announced.
The current minimum age for someone wanting a career on the railways is 20.
But with 87% of night-before cancellations made because a driver is unavailable, the government has decided to lower the age of entry by a couple of years.
Several operators rely on drivers to work extra shifts voluntarily.
At present, the average age of a British train driver is 48, while 30% are due to reach retirement age by 2029.
A consultation on lowering the minimum age for drivers, carried out last year by the Conservative government, received "overwhelming support from across the industry", the DfT said.
Other nations which have lowered the age for train drivers are France, Germany, the Netherlands and Switzerland, officials added.
Transport for London opened driver apprenticeships on the Underground to 18-year-olds in 2007.

Industry body the Rail Safety and Standards Board said its research had shown 18-year-olds are "capable of safely becoming train drivers".
New job and apprenticeship opportunities could be available as early as December, the DfT said.
Heidi Alexander, the transport secretary, said the government was "future-proofing" the railways against "delays and cancellations caused by a shortage of drivers".
Mick Whelan, general secretary of train drivers' union Aslef, said: "At the moment, young people who want to become train drivers leave school or college at 18, get other jobs, and we miss out as an industry as they don't wait around until they turn 20 to find a career."
