1. A retention device to retain a railway tie plate, the retention device comprising:a head section comprising one or more protrusions adapted to engage a railway rail;
an insert section adjacent to the head section, wherein:
the insert section is adapted to fit in a spike hole of a railway tie plate; and
the insert section comprises one or more flexible members extending from the head section, each flexible member adapted to allow flex adjustment having at least a lateral component with respect to a longitudinal axis to engage the railway tie plate when the insert section is inserted in the spike hole of the railway tie plate;
wherein the insert section fits into the spike hole of the railway tie plate so that the one or more protrusions engage the railway rail and the insert section engages the railway tie plate to mechanically interlock the railway tie plate with the railway rail to allow suspension of the railway tie plate from the railway rail without a railway tie.
