I have been looking over my narrow gauge card file over Xmas vaction. There are a number of preserved cars that building data for.
For ex, D&RGGW boxes 3007,3117,3098 at Fort Lupin.
More boxes at Georgetown Loop 3400, 3500 series.
There are enough D&RGW books to sink a battleship! Which ones will help on freight car history? I guess I am looking for the freight car equilivant of the CRRM Annual #24 on passenger cars.
Thank you for your suggestions. TM
