A dramatic night out with the A1 Steam Locomotive Trust. I was given exclusive access to their attempt to run their brand new steam engine Tornado at 100mph.

In order to gain certification to regularly operate at 90mph, one of the tests required was to check if it continued to operate safely above that speed.

This is the first time a British Steam Locomotive has run at such a speed, since the phasing out of steam on BR in the mid to late sixties. An A4 class was given permission to run at 90mph for a special occasion in the 2000s but not 100mph.
