FIG. 1 is front view of a railway crossing signal display showing my new
design, the human head-like image being shown in broken lines facing
forward;
FIG. 2 is a front view thereof, the human head-like image being shown in
broken lines facing in a direction between forward and sideways; and,
FIG. 3 is a front view thereof, the human head-like image being shown in

purposes only and forms no part of the claimed design. It being understood
that the sides have no substantial thickness and the rear is plain
