Quad GP9's. Four GP9's (CN 4102, CN 7275, CN 7017 & CN 7031) are in charge of CN 527 today, operating on the transfer track. This track has primarily been used for storage of cars the past few years, but since CN cleared the growth from this track a month ago, there has been an increase in traffic on it.
