Thomas the Tank Engine’s Secret Adult Fandom: Inside 2025’s Most Surprising Documentary

Remember that blue locomotive that dominated your childhood telly? Well, turns out some of us never quite left the Island of Sodor. And when I say ‘some of us’, I mean a proper global underground movement of grown men who are absolutely chuffed about their Thomas the Tank Engine obsession.

The Secret Life of Adult Thomas Fans

Matt Michaud’s living room looks like any other twentysomething’s space – until you spot the meticulously arranged Thomas the Tank Engine models. “I kept it a huge, dark secret,” he confesses in the opening moments of 2025’s most eye-opening documentary. Blimey, you’d think he was admitting to something properly dodgy, rather than a passion for everyone’s favourite steam engine.

But here’s the thing – he’s not alone. From Birmingham to Boston, Tokyo to Sydney, there’s a whole community of millennial blokes who’ve turned their childhood love into a full-blown adult obsession. And they’re finally coming out of the signal box, so to speak.

Why Thomas? Why Now?

The timing of this documentary isn’t random. We’re living in an age where nostalgia’s become proper currency – just look at how Pokemon’s still massive and Furby’s made a comeback (heaven help us). But Thomas? That’s different.

“It’s about more than just collecting toys,” explains Dr. Sarah Henderson, cultural historian at King’s College London. “These fans are preserving a piece of British cultural heritage that speaks to something deeper – craftsmanship, community, and a simpler time before smartphones ruled our lives.”

Breaking the Stigma

Let’s be honest – admitting you’re massively into Thomas the Tank Engine at 30 isn’t exactly the sort of thing you lead with on a first date. But the documentary shows how these superfans are challenging the stigma, one model railway at a time.

Take James Patterson (not that one), a 28-year-old investment banker from Manchester: “Yeah, my mates gave me stick at first. But then they saw my collection, the detail in these models, the history behind them. Now they’re proper interested – even if they won’t admit it down the pub.”

The Global Express

Perhaps the most fascinating aspect is how Thomas has transcended cultural barriers. Japanese collectors are particularly devoted, with some spending thousands on rare merchandise. The documentary showcases monthly meetups in Osaka where businessmen swap trading cards and debate which episode best captured The Fat Controller’s character arc.
