It received two nominations and it could be described as a minimalist railway station, that is, there is eff all there. I speak of Rockbank Railway Station.
Admittedly it is not part of our suburban system, but on the outskirts. Due to growth in the population of that area in the west, it has become a very busy station and certainly is ripe for a decent station befitting its passenger numbers.
From an interesting comment from Daniel, I spent a little time investigating Balaclava Railway Station. It was badly damaged by fire on the 9th of April, 1929 and repaired. It was again rebuilt in 1981 but without any reason that I can discover.
As you can see int the photo, Rockbank Station consists of shed on one platform and a old style bus shelter on the other. From Google Street View, it looks barren and desolate without decent paths to it.
I am used to decent railway stations, ok some a bit old and shabby or nasty newer ones. There is another that I laughed at when I saw it, somewhere between the city and Footscray I think. Not much more than a bus shelter.
