Athearn Blue Box F7 A/B set custom painted decaled and detailed by the late Alden Clark. He used Proto Power West drives on A & B units equipped with Sagami can motors. He also used seperately applied stainless steel grill intakes, window wipers, coupler cut bars, kadee couplers,, and hand grabs/ladder bars. These were DC only so when I recieved them I did a complete drive cleaning and thend added Loksound Select DCC decoder and iPhone 5 speaker in 4265 and installed in 4267B an Athearn Genesis motherboard with JST & 8 pin plug with 8 pin TCS Decoder. These run very well and pull a train up a 2% grade with no issues.
