Secret men's business (aka Steamfest)

I managed to catch the 3642 heading back from Branxton in between visiting the nursing home and mowing, asyoudo.  During steamfest you can see lots of trainspotters at strategic locations long the line.  They are the ones now looking at their apps to find out precisely when the train left the station, which line it is coming in on and what number the engine is.  A highlight this morning was a graincorp train (that had me stumped)  Consideration is given to the angle of the shot (above, side on etc) and where it will go in the collection.  Most definitely Secret Men's Business I think.
