Weathering railroad track

My first trial on weathering rails and ballasting the track:

2014-12-20 14.54.17

used artist’s acrylic to blend a reddish/rusty hue and applied it with a brush to the sleepers and the rails. Then applied grey granite ballast (from Noch) and used a dry brush to remove it from the sleepers and to shape the outer ballast bed. To fix it in place I applied water diluted PVA glue with a tiny drop of soap. Finished it with 2.5mm grass (from Noch) and a tiny bit of GroundSoil (from SceneryScapers).
