I am basing my Garden RR on the Dolly Varden Mines Railway in Northern British Columbia. I would like to hear from anyone out there that may in modeling or have an interest in the DVMR.
Thanks,

John beat me to the same recommendation 
If you have access to back issues, there have also been many indoor layout articles of this line in the “Narrow Gauge and Shortline Gazette” that are good reference materials.
