Superdetailing a PRR F7 in S Scale

The author modified the A-B-A set of S-Helper Service PRR F7 models by adding opened front coupler doors, Pennsy nose lift rings, and additional grab irons. The PRR antenna took a bit more work. The author built a brass drilling jig, so that he could properly position the stanchions for the antenna, and duplicate that effort on the other A-unit. He tested the A-B-A consist to work properly in DC (required some electrical work), before installing DCC. The article ends with how he painted the modified areas and applied weathering.

The Erie F7's and the John Armstrong Story
