It was a long, cold winter according to Craig McMullen who built this model of Piledriver OB. It is a remarkable achievment, with exquisite detail, and many functioning parts. The mast will raise and lower, and the bracing is very accurate. There is a model (but not functioning) steam engine in the cab that can be seen through the open door. He even made a tender car to accompany OB. The photos were taken on Craig's garden railway. For newbies to this site, the real OB was recently restored by the Friends here in Colorado Springs, and was returned to the C&TSRR last year for display. It is planned to be loaned to the Colorado Railroad Museum in Golden this summer, arriving in late June.
