I don't know if this has been mentioned elsewhere but there is a 30minute programme on BBC4 tonight at 8:30pm about the Flying Scotsman.
It's a repeat - was first shown in early March.
It's a bit of a rail documentary repeat night - the programme on Channel 5 at 8pm has also been shown before.
May I ask what is the Channel 5 programme?
Exploring four historic engineering breakthroughs that paved the way for France's TGV, which regularly reaches speeds of 200mph on some services and has been pushed to nearly 360mph in special tests. The programme looks at four key steps in the development of high-speed technology, including George Stephenson's 19th-century Rocket and the Japanese Bullet Train.
