For the sand red color you would probably have to use the back of 2×2 slopes because they are much cheaper than 1×2 bricks.
The station is actually brick red. In the picture I pulled earlier, the sunlight made the bricks look washed out and Sand Red in color. Whew, dodged a crippling financial bullet there. The mansard roof is mainly sand green and the entire station design is reminiscent of French Revival architecture.
