Sorry, bit late in spotting this.
BBC2 tonight 21.00hrs - The Genius of Invention
Deals with the jet engine, the infernal combustion engine and, of course, the steam locomotive.

No need to apologise, it has already been programmed into the tv to switch on/ over at correct time 

cheers John.

 I was a bit disappointed with the one on "power" in some respects but pleased that, whilst lauding Boulton & Watt, they did point put that their aggressive patent protection held back development of steam.

I guess in the length of the programme they can't cover everything but the talked about Parsons and turbines with no mention of Cragside and Turbinia.
