English term or phrase:"drive-on" system
"The uniform toe load plus creeplok feature ensure that the Unit Rail elastic fastener system will always develop much more rail longitudinal resistance than the ultimate ballast resistance. The Unit Rail system is a ***"drive-on" system***. Unlike other fasteners, it has no threaded parts, which can corrode, loosen over time and reduce clip load and longitudinal restraining power."
