Slab Track vs. Ballasted Track

Comparing slab track and ballasted track, slab track offers several advantages:

  • Low maintenance
  • High availability
  • Low structure height
  • Low weight

Life cycle studies suggest slab tracks can be cost-competitive. However, slab track also has disadvantages compared to ballasted track:

  • Higher construction costs
  • Higher airborne noise reflection
  • Difficult alterations in track position and superelevation
  • Limited displacement allowance in the
