It won't surprise you that I did know this; I got a hot tip from my elder brother.
I came from a family where second sons were very much second-rate, (and don't get me started on the position of women in the hierarchy), and I was therefore expected to go everywhere my brother did and do everything he did. When he acquired an unhealthy obsession with railways, around the age of 10, I got dragged around the railway depots and works of the UK. Fifty years on, he still has an unhealthy obsession with railways, and I have been left with a deeply ingrained interest.
In the spirit of 'anything you can do, I can do better', here is the photo he took at Stafford station, an hour before it reached me. And yes, you can see 57012 behind, hitched up for the ride.
