Rail tracks are normally laid on a bed of coarse stone chippings known as a ballast, which combines resilience, some amount of flexibility, and good drainage; however, track can also be laid on or into concrete (a slab track). Across bridges, track is often laid on sleepers across longitudinal timbers or longitudinal steel girders.

Do you mean the railway bed if so it is for drainage so when it rains water will seep away from the tracks HAPPY DAY

Drainage! Standing water on tracks is not good, especially with wood ties... Keeping weeds off the RoW... Helping define the RoW, and in a way helping hold the track in place.
(RoW = right of way)

I think to absorb some of the vibration of the tracks when a train goes by.

For drainage and to prevent the growth of plants, also helps distribute weight of train evenly.

I would guess to assist in weeds/shrubs NOT growing in the right of way and provide drainage.
