With adoption of welded rail and elastic rail fasteners, French National Railways found it necessary to improve the concrete cross tie. Although the twin-block type has been most widely used and has advantages including lateral stability, light weight, absence of center cracking, and low cost, it does have limited bearing area and tendency to gauge widening. SNCF again began investigation of the monobock design. Studies have included redesign of the twin-block design with greater strength and bearing area, along with improved bonding of the tie bar. The monoblock design is of particular interest for lines where they will replace wood ties out of face.
