All aboard for the world of railway engineers – the ultimate problem solvers who design, build, and fix everything that keeps the trains running! Emma-Louise and Lauren discover how Victorian engineers and an army of 'navvies' turned muddy roads into a nation of iron rails, even floating a whole railway across a swamp.

Meet the legendary Sir Nigel Gresley, designer of the record-breaking Mallard, watch engineering giants like the Stephensons and Brunel go head-to-head in our Great Railway Rumble, and hear jaw-dropping stories from Network Rail archivist John Page.
