The Great Model Railway Challenge

Grand Final: Surprise Surprise (2x8)

Air date: Oct 26, 2019

In an extended edition, four finalists have three days to create miniature railway layouts that must amaze, confound and delight, before the winner is announced. Judges Steve Flint and Kathy Millat cast an expert eye over designs that include an homage to Hamburg's Miniatur Wunderland, an eco research centre, and an Austin Powers-themed layout.
