The F7 primarily differed from the F3 in internal equipment, but there were some noticeable external changes such as the grills and the dynamic brake hatches. In this production, we are modeling A and B-units from eight railroads with prototypically accurate road numbers and paint schemes. We are offering A-B sets with Powered A-units (w/ Paragon4 Sound) and unpowered B-units, and also separate single A and B-units with our full Paragon4 DC/DCC/Sound system.All of our models have road-specific details and lighting.
