Looking for resources on Kansas City SLSF and BN yards.

[Brickrail782]

I've got some freetime on my hands, and as such I've decided to get back into TS route building. I'm currently working on the former Frisco mainline from Kansas city to Springfield, set in an ambiguous period between 1980 and 1999. I've decided to start work on the yards in the KC area (Rosedale, Glen Park (MKT), 19th St., and Murray), but I'm currently at a loss on where (or how) to find yard diagrams (or at least detailed aerial photography).
