It is a bit visually confusing, as that corner of my land is a bit crowded, but maybe I'll think of something else to help set it off. The plantings around the platform have helped somewhat.
The groined vaults are sculpies by Ms. Dimsum; the column decorations are also a sculpie, this time from the free sculpies in Victoria City. I've used several textures which I already have on my land so as to minimize texture lag; the only new texture is the 512x128 "Caledon Brigadoon" sign. The shelter was inspired by a number of Victorian-era train stations and shelters.
Should anyone else like a rail shelter like this one, please speak to me. They're cheap. ;)
