The Material World. As the world faces up to shrinking oil and gas reserves the programme asks what alternatives can be found. Looks a bit heavy science from the press release, readers.

Top Marques: Ferrari. Did you collect car brochures as a child?
Have you ever bought a snazzy new steering wheel to replace a rather dull looking one? Do you wear driving gloves or ones that are perforated at the back? Do you think Jeremy Clarkson is funny?
Then what are you waiting for - don't let Arthur in Cheltenham watch alone.
Discovery Sci Trek 12 noon Routes: The Settle to Carlisle Railway. Between 1870 and 1875 a 115km express train route was carved through the rugged and windswept Yorkshire Dales. Ladies and gentlemen, lightly chill several cans of Tetley's bitter and take a journey through the 16 tunnels and over the 14 viaducts and marvel at the work of those hardy Yorkshire folk.
Discovery Civilisation, 1pm
Invisible Places: Subtropolis.
Looks at the infrastructure of the city, starting from the Roman aqueducts to the substructure of places like the Sears Tower. Nice.

Conspiracy Theory. Film starring Mel Gibson. A national railway network is sold to private enterprise which mercilessly plunders it to fund excessive executive salaries. All this is to the detriment of the industry, which finally collapses after being bled dry. Gibson tries to make sense of the story and finds the whole mess goes straight to the top of government and a mysterious Mr Big nicknamed The Major. And the moral of the story? Well, would you let Fatty Arbuckle look after the candy store? Julia Roberts co-stars as the woman who punches Gibson's ticket - in a wholly euphemistic sense of course. Channel 5, 9pm
Blue Peter. Yes, that's right friends. National Construction Week is upon us, and today the entire programme comes from the CITB's National Construction College at Bircham Newton.
Perhaps this could be the turning point for some youngsters out there whose days of sticky backed plastic and empty washing up liquid bottles are nearly over. Alas though, Shep is no more. BBC1, 5pm
