== The Final Years == 

 In reviewing this section, I've noted several corrections that need to be made.  For instance, while Edison did ride the first Lackawanna Railroad electric train from Hoboken to South Orange, NJ in September 1930 (not Gladstone, NJ in 1931), he only played the role of engineer as far as the end of Hoboken yard (about one mile) and not all the way to Gladstone (42 miles), which is a big difference.  Also, Edison had very little, if any, involvement in the Lackawanna Railroad electrification project on a whole, whereas the article states that Edison was closely involved with the project, which isn't true.  The Lackawanna project employed the use of direct current (DC), which Edison advocated over alternating current (AC), but that was the extent of Edison's "involvement".  Anyway, I see that that the article is "protected" from editing.  I'm wondering what permission I require in order to revise this part of the article.  I don't have any interest in revising any other part of the article at this point.  What do I need to do?
