Great Electric Train Show 2026 reveals first layouts and revived Seven Mill Depot

The first layout reveals for the 2026 Great Electric Train Show give the event a proper head start, and the biggest hook is not subtle: Seven Mill Depot is coming back after a full overhaul, while Ron Bailes is bringing a brand-new 43ft x 15ft O gauge layout that models East London in the 1960s and will make only its second public appearance after more than five years of work.

The show runs on October 10 and 11, 2026 at Arena MK in Milton Keynes, with more than 30 hand-picked model railways, more than 50 trade stands and expert modelling demonstrations built into the bill. Advance tickets are already on sale, with adult admission at £18 and children at £9. A free shuttle bus will run from Milton Keynes Central station, and children go free on Sunday when accompanied by a paying adult.

For layout watchers, the first reveal is strong rather than safe. Phoenix Lane, Penhelig, Five Mile House, Providence Colliery and Portcreek are all in OO, while Lizworth Bay brings N gauge into the mix. That spread matters. It gives the show a wider visual range than a line-up stacked in one scale, and it means more chances for club builders, photography fans and social media scrollers to find something worth stopping for. Five Mile House, exhibited by Lincoln and District Model Railway Club, adds another familiar name, with its Lincolnshire bargee and river-side backstory giving the layout an instantly legible real-world hook.

Ron Bailes’s new O gauge build looks like the sort of thing that will pull visitors across the hall on its own. At 43ft by 15ft, it is large enough to carry serious scenic work and operating interest, and the East London 1960s setting gives it the kind of urban grime and freight-era detail that always plays well in a show setting. Seven Mill Depot should draw a different kind of attention. First built in 2019, it is being revived for the 2026 exhibition with a late-1990s to early-2000s theme, so it will not just be a rerun of an older favourite but a fresh take on an established layout.

The trade side already looks useful too, with Cavalex, Hornby and Revolution Trains confirmed alongside retailers and specialist stands. That mix gives the Great Electric Train Show the right balance of spectacle and spending temptation, which is usually what turns a strong weekend into a must-travel date. More layout announcements are due next month, but the show has already done the important thing: it has put scale, variety and a revived headline layout on the board early enough to start planning around them.
