### Instruction: What was the final name of Great Northern in this passage
### Input: Due to its historical roots as a town housing railroad workers, Hillyard acquired a rather rough reputation, which lasts into recent decades. (As recently as 1979, Daniel Leen described the Hillyard train yards in his book The Freighthoppers Manual for North America as having "the feel of warmed-over death.") After the Great Northern underwent a series of mergers, becoming the Burlington Northern Railroad and eventually the BNSF Railway, the Hillyard yard and shops were closed in the early 1980s with BN's main yard operations in Spokane moving to Yardley. Only the decaying structures of the old shops remain today. Hillyard suffers some of the worst poverty in Spokane, per capita it is the poorest neighborhood in the state of Washington. The eastern border of the neighborhood, east of the railroad tracks, is sometimes affectionately referred to as "Dog Town" by some residents
### Response: After the first merger Great Northern became Burlington Northern Railroad, then eventually BNSF Railway.
