Building the Impossible Railway
A dramatised documentary in six parts
The story of the struggle to build Canada's first intercontinental railroad begins soon after Confederation - the official start of Canada as a nation. This is the dawn of Canadian Parliamentary history, with the first Prime Minister Sir John A. Macdonald , striving to unite the country by a railroad. The West Coast province-to-be of British Columbia was still not a part of the Confederation, and their price was a rail link with the East. But there were formidable obstacles. They included the natural ones, of immense distances, the towering Rocky Mountains which were far from fully charted, and the swamps and rocks of the Canadian Shield, a huge mass in Central Canada skirting the wide prairies. American machinations and lack of support from Canadian investors were almost equal hazards, and threatened the project from its inception.

Comprehensive redevelopment has changed the face of British cities more drastically in the past 20 years than they had altered in centuries. Cardiff was the last of the large cities and towns to take the plunge into concrete and glass: after 20 years of argument, the Council teamed up with Ravenseft Properties to produce plans for the biggest central area redevelopment in Britain.
A year ago we showed a 90-minute investigation about the future of Cardiff's plans and how they related to the host of other problems. Since then, the property market has collapsed completely and the Ravenseft contract has foundered before it began.
Tonight, Roger Graef , film-maker and planning critic, reviews the events leading to this crisis.
