and the underlying
         reason for the change. Also note citing noncash items (such as
deferred income taxes) and
         net earnings may not provide a sufficient basis to understand how
actual operating cash
         was impacted. Refer to section IV.B.1 of SEC Release No. 33-8350 for

         Transportation will be assumed by, Wabtec. Please confirm all assets

      of GE Transportation are not in the financial statements but potentially
may be, please
      provide in an appropriate section of the filing summarized information of

Note 7. Property, Plant and Equipment, Net, page F-25

25.   Please explain the reason why depreciation expense disclosed herein
decreased to
      $112,283 thousand in 2017 from $171,776 thousand in 2016.
Note 13. Income Taxes, page F-29

26.   In the reconciliation of U.S. federal statutory income tax rate to actual
income tax rate
      table, please explain why the amount of foreign operations and foreign
tax credits for
      2016 is significantly larger than the amounts in the surrounding years.
Note 19. Segment Information and Major Customers, page F-36

27.   The segment profit for the equipment segment decreased significantly in
2017 to
      $(25,907) thousand from $142,508 thousand in 2016. This decrease appears
to be a
      material driver in the variance in results between 2017 and 2016 but
there appears not to
      be any analysis of it. Please discuss the reason for the decrease.
        We remind you that the company and its management are responsible for
