Govia Thameslink Railway (GTR), which operates Thameslink, Great Northern, Southern and Gatwick Express, said it wants to recruit people and teach them how to maintain its fleet of trains.
The course is a mixture of practical and theory learning, leading to a UK-recognised trade qualification.
Anyone over 16 years old can apply, but they must have a minimum of a level 4 (grade C) GCSE in maths, English and science to be eligible for the role.
Katie Short joined GTR in 2023 and says she is hoping to qualify as a level 1 service engineer.
The 22-year-old said: “I’ve always enjoyed practical, hands-on jobs, so I wanted to take this passion and apply it to an industry where I could create a longstanding career.
“I wanted to make a difference and be part of a team which helps keep our trains running safely, so I applied for the apprenticeship and haven’t looked back since.”
Cameron Wytiahlowsky, engineering apprentice trainer assessor at GTR, said: “We’re looking to recruit the next generation of engineers who are ready to take their first steps on the career ladder.
"This is a fantastic opportunity to earn a real salary, whilst learning the trade."
Applicants must be able to travel to East Surrey College and various locations on GTR’s network for work, the train company said.
