This is the BR standard class 7 70013 Oliver Cromwell, which I randomly took some pictures of today because I found out it was going to stop by my local station to top up on water. I'm not a train spotter, nor am I a photographer. IT JUST HAPPENED.
An incredible amount of people gathered on the platform, some there for this train, some just happened to be waiting for their own trains, and everybody was going "COOOOL" and taking pictures. XD
When she finished drinking from the water hole and the engines started again, the whistle nearly blew my ears out. They're still ringing a bit right now. @.@
