Melville Fuller,
Southern Pacific Company v. California…
“ We recite the most essential features:Section 1 authorized the Atlantic & Pacific Railroad Company to construct its road, vesting it with all powers necessary for that purpose (14 Stat. 293) ; and section 3 made grants of land to the company 'to secure the safe and speedy transportation of the mails, troops, munitions of war, and public stores' over the route of its line of railway and branches (Id. 294) . This was a plain exercise of the power 'to establish post roads,' and of the implied power to construct military roads. ”
