Right out of the WSOR paint shop in Horicon - Wisconsin Central SDP45 never looked better. Of course the WC had plenty of SD45s but this was the only SDP45 the WC ever had on their diesel roster. About four years after I took this photograph, during the first year of CN ownership of the WC, the 6634 was sold at auction and eventually ended up down in Mexico I am not sure if it still survives.
