Pierce Butler, United States v. Illinois Central Railroad Company…
“ As between the government and respondent, the latter's breach is precisely the same in kind and degree as it would have been if its yardmaster's failure had been intentional instead of merely negligent. The duty violated did not arise out of the relation of employer and employee but was one that, in virtue of the statute, was owed by respondent to the shippers and the public. As respondent could act only through employees, it is responsible for their failure. ”
