6 part series starting on Channel 5 on Friday at 8 pm.
This is what the Radio Times says about it which is quite positive, so may be worth a look at:
Don’t let that generic title (“great” and “challenge”) put you off, this is a lot of fun, and you don’t need an abiding love of railway modelling to enjoy it.
In the first heat of the competition, teams Strangers on a Model Train, Team Porthcawl and the Missenden Modellers have three days to construct layouts based on “classic movies”.
The judges – modeller Kathy Millatt and journalist Steve Flint – patrol with gimlet eyes, and there’s an early scandal when one group is ticked off for bringing in too many pre-built pieces. Will this infraction jeopardise their chances of going through to the final?
But there’s real ingenuity in the builds and there are even a few tears when a captain is overcome with emotion as he marvels at his team’s creation. It’s all so well mannered, too – one contestant offers his home-baked Welsh cakes to everyone, including his rivals.
Summary
James Richardson and Tim Shaw lift the lid on a globally popular hobby, beloved by legions of unsung artists who have been quietly building tiny universes for the littlest of locomotives in attics and sheds for decades. Here, teams of the UK's most talented railway modellers compete in a series of knockout heats to create jaw-dropping miniature masterpieces against the clock. The first heat sees Strangers on a Model Train, Team Porthcawl and Missenden Modellers compete. The judges are editor of Railway Modeller Steve Flint and renowned modeller and vlogger Kathy Millat.
