"If I could go back and talk to my 18 year old self, I'd force myself into the railway," said Ben Warner, a recently qualified train driver.
Mr Warner, who works for Great Western Railway (GWR), is nearly 40 but from December could find himself surrounded by teenagers as the minimum age for train drivers has been lowered from 20 to 18, to help with driver shortages.
Based at Westbury, Wiltshire, he told the BBC: "Look out of the window – best office in the world."
With the changes set to come into place later in the year, we take a look at what is involved with training and qualifying to become a train driver.
Adam Walding is a driving standards manager with GWR – drivers in training get their final tests with him.
He explained training is usually about 10 months, including three to four months of theory – covering what everything in the cab does.
There is then another process for a few months of sitting with drivers, who will give you "direct instruction, as you progress, that instruction reduces".
"You then have a five-day final driving test with somebody like myself."
He said that to get into training at 18, people need to think about their transferable skills: "Start building your CV – what does a train driver do? What do I do?
"My first job for example was working in a shop, I used some of the safety examples from that in my interview."
Mr Walding said someone's age should not make a difference: "If someone has the right transferable skills, age shouldn't be a barrier."
Meanwhile, Mr Warner said he enjoys his work, but admitted it is a "massive responsibility".
"The training GWR put us through is so rigorous. My first day as a qualified driver, I felt ready to go, I felt in a really strong position to take the train where it needed to be."
