MFS own land in a number of places in both metro and near fringe areas
Likewise they have owned land before in CFS areas and then sold it!
They have enough problems with their current stations (ever spend any time in Glynde or Glen Osmond - both are rather dated and slowly falling apart.
We could all speculate on where, when and why MFS will build stations, however I think they have enough problems in Adelaide - with gaps that they need to fill first!
As for the stations in the country areas (some one said riverland) - all retained crews and stations range from the palace at Renmark to old and tied stations in other areas!
As for the UFU - they are a union - it's their job to stir the brown stuff - thats what they are paid for and they have been good at it over the years - looking after their members and ensuring the brown stuff is always just balancing below the fan - ready to hit it when the need arises
