Interesting to note that whoever was firing didn't fire the front of the box. The engine was obviously steaming hard enough to pull the fire forward.
I certainly wasn't criticising the firing, just making an observation about firing technique.
Believe it or not, I learnt this on a PBR NA of all things. We were 8 minutes late out of Belgrave on a down Lakeside, with 14A hauling 10 vehicles crammed with passengers. The driver, one of the great ex VR characters ( no names, but his initials are Lyn Helsby ), announced to me that we were going to "get over the bridge, warm her up, and make up the time."
As he started to steam hard up the grade, he called to me, "Don't fire the front of the box, I'll pull the fire forward." He did just that and we made up 7 of the 8 minutes to be down 1 at Menzies Creek.
Having digressed enormously, I will now shove off !
