I'd say that they are on their way out as a passenger loco with VLP but I'm sure freight operators would be more than interested in them. Considering that they are taking away A class allocated runs as each new vlocity is introduced they would be disappearing sooner rather than later. I cannot envisage them being allocated on other pass services with the surplus of N's but I could be wrong. When the Sunbury & Geelong runs are changed as mentioned that will only leave the 1645 Bacchus Marsh commuter which I'm sure is earmarked for an N or velocity in the not too distant future.
Hopefully someone in the know can advise further!
