The model was built from measurements taken a couple of years ago. One main point in measuring a building is to check one has all the required data before leaving, as there is nothing worse than preparing a drawing later to find you have forgotten an important measurement. Like the height of the walls. Four and a half hours each way is not on just for a stretch of the tape measure.
Lucky, I found a drawing of Talbot, through a search engine and guessed that most station buildings would be much the same height. This was later confirmed on a recent pass through while heading to Melbourne by car, instead of flying.
The real thing.
