Atlantic City Railroad Co. v. Parker
Atlantic City Railroad Co. v. Parker, 242 U.S. 56, 59, 37 S.Ct. 69, 70, 61 L.Ed. 150 (1916), suggests that whether a coupler failed to couple because the drawbar was misaligned is a question for the jury.
The Court there stated that "a jury would be warranted in finding that a lateral play so great as to prevent coupling on a straight track was not needed, and that, in the absence of any explanation believed by them, the failure indicated that the railroad had not fully complied with the law." Ibid .
