There is provided a brake lining for a railway vehicle that can reduce brake squeal in braking. A brake lining for a railway vehicle is used for a disc brake system of a railway vehicle. This brake lining includes a base plate, a sintered friction material, and a friction material supporting mechanism. The friction material supporting mechanism is disposed between the base plate and the sintered friction material and supports the sintered friction material in such a manner that the sintered friction material can move with respect to the base plate. The sintered friction material has a Young's modulus of 35.0 GPa or more.
