NSWGR_46Class
Just call my Captain Rude
I have allowed for every possible combination I am pretty sure that green C36's ran on the Central West Express
As far as I recall no belpaire boilered pig was ever painted green in NSWGR service - all were in the standard black with red lining. 3616 was painted green in the early 70's by the NSWRTM for its final year or two of restricted traffic service ( the most recent contemporary shot I have of her in steam , taken on the 12 dec 1970 she was still black) , and of course 3642 was also painted green when overhauled and returned to service in the 1980's
*Edit - have just gone thru some more pics: a trip to enfield in jan 1972 shows 3616 was green by then, so she was repainted sometime during 1971
