Swan Hill is the terminus of a short, double track commuter branch off the GWR in the vicinity of Langley, imagined/modelled in 7mm. The last mile or so of the branch, including Swan Hill station, is carried on viaduct – Windsor comes to mind. The track plan owes something to Uxbridge Vine Street but with only a down siding for reversing into a goods yard (as per Windsor but off scene) and an up siding, shunting spur and dock. There is a single passenger platform serving arrival and departure roads. As at Uxbridge, there is no engine release crossover, so trains reverse and run round outside the station and in doing so, move from part 1 of the model - the station - to part 2 which will be in an adjacent covered area and may never consist of more than a sector table.
As there is little room for much width to the model (it's basically 600mm wide), height has been used instead, thus the viaduct. The dotted lines on the drawing show roads and lanes under the viaduct based pretty closely on Fenchurch Street/Crutched Friars (wrong company but never mind) with pubs and other enterprises waiting to be installed underneath. It is not intended to develop goods facilites at ground level – these are “off scene” allowing goods trains to appear and reverse into part 2. It is planned that there will be sufficient building appearing above the viaduct formation level to give the impression of a very constrained town centre site where the road and building layout pre-existed the GWR's intervention in providing the citizens of Swan Hill with a railway station.
