As an indication of how much consolidation and merger there has been in the railroad industry in the last fifty or so years, consider that only five Class 1 Railroads from before the Great Depression still exist, to the best of my knowledge. They are:

  1. Union Pacific
  2. Kansas City Southern
  3. Florida East Coast
  4. Canadian National
  5. Canadian Pacific

The rest either went bust, were assimilated by a larger company, or participated in a merger of more or less equals where the merged company carried a name different than any of its constituents.
