Actor Peter Davison, presenter John Sergeant and steam buff Paul Middleton join forces, as they attempt to travel from London to Scotland using only the power of steam.

The trio travel from Peterborough aboard the 92 Squadron steam train, then visit the original Thomas the Tank Engine in Wandsford and take a steam barge up the Grand Union Canal.

The intrepid trio continue their journey: first on a 21-foot steam launch called Bruin, then driving a 1908 Stanley steam car, and taking in a visit to the North Yorkshire Moors Railway.

John, Peter and Piglet are on the last leg of their journey: from Whitby to the Scottish border. They travel by 1937 Steam Lorry, train, a steam launch and a beautiful steam car.

Join steam fans John Sergeant and Peter Davison on a rollicking adventure, as they try to cross Britain by steam. They soon run into trouble in the spectacular Lake District.

The steam buffs travel to the Isle of Wight on the Waverley paddle steamer, then ride a hundred-year-old Sentinel steam lorry, steam railway, and a small and uncomfortable steam roller.

Peter Davison and John Sergeant head to the Dorset coast to rediscover childhood memories, stunning scenery, scrapes aplenty and a bone-shattering cider wagon ride.

The steam buffs travel through the stunning Scottish Highlands via an exclusive steam car, a boat that blows a gasket on Loch Ness, and steam truck Helen Laddy.
