In this type of rail, the head is made little thicker and stronger than the lower part by adding more metal to it. This rail s also require chairs for holding them in position. Bullheaded rails are especially used for making points and crossings.

- These rails are easily removed from sleepers and hence renewal of track is easy.
DEMERITS:
- B.H.rails requires additional cost of iron chairs.
- These rails require heavy maintenance cost.
- B.H. rails are of less strength and stiffness.
