I think it depends on the location/environment that a particular secton of track is located in.
IMO woodland Scenics Rail Brown is a good start. We all know how it looks when rails are painted "rust color" Eventually I want to brush some rust/grime weathering power on the plastic roadbed and tie it into the ballast better.
For those painting fastrack its important to include the very top edge of the plastic base where the simulated spikes are.
This actually represents the flared out bottom of the rail. Painting this edge helps, tone down the upside down "U" shape that fastrack has by design.
