Station buildings in double

I've made some alterations to the original pre Southern station building by making my own roof tiles and pasting these over the painted version. In addition I've now made some useful progress with the Outback model of the station building in Southern extension period. Neither are finished but I've decided to now leave the final finishing until the model is running in a very smooth efficient way and some progress made to the scenics. My order of priority now is 1) - track work and electrics : 2) a start to scenics and 3) finish the buildings. Finally the track will be ballasted.
