I provided Weaver the PRR prototype painting and lettering information for the BP20 project. My source was the official PRR diagrams published in the Pennsy Journal back in the 1970's. The planned second production run featuring the broad single stripe Tuscan red passenger scheme and the narrow single stripe DGLE (Dark Green Locomotive Enamel) freight scheme never went into production - apparently due to due to lack of interest. With the decline in passenger traffic in 1953 the PRR re-geared 4 cab and 4 booster units for freight service. Down- rated to 1600 HP they were re-classed to BF16z. For prototype info and pictures see Pennsylvania Railroad Diesel Locomotive Pictorial - Vol 4 - Baldwin Cab and Transfer Units by Hohn Hahn.
I upgraded my five stripe DGLE A-B BP20's units with QSI Titan Magnum DCC decoders, and I fixed the swinging A unit pilot. Other than the die cast trucks, the unit is fabricated from sheet brass. As I recall there are lead weights in the fuel tanks of the 2 rail units. With 4 motors and lots of weight they easily pull 11 GGD 48 Broadway cars up a 2.2% grade. No traction tires required!.
