A boltless, friction-fit adjustable brace for bracing rails on a tie plate wherein a plurality of friction surfaces of a removable side brace engage corresponding surfaces on a rail. The brace is provided with a serrated portion on its side for engagement with a serrated washer, which washer has a pair of ear lugs which span and contact a mounting plate on the tie plate. Finally, a resilient spring clip is applied thereto to engage the serrated washer, to prevent longitudinal, lateral and elevational movement of the side brace, when the rails are under load.
