C&TS Work Train Photos

I am planning forthcoming parts of my "Along the Narrow Gauge" series in the NG&SL GAZETTE for 2016. Two of the articles will feature photographs, history and scale drawings of D&RGW Pile Driver OB and Derrick OP. I will not be able photograph the Special on Oct.3rd and 4th and am looking for someone who can make a few photographs of both OP and OB in service for use in the magazine, with proper credit. There is no rush, but I'll need a few views (600 dpi b&w or color) that can be sent by email. In short, as the old song sez, I'll get along with "A little help from my friends". Thanks!
