  • Identification of ballast grading for rail track

    Ballast is the largest component of the railroad track, which shares a significant part of the entire railroad budget for purchasing, distributing, and maintenance. Ballast grading fundamentally determines its physical and mechanical characteristics. The size of ballast was usually determined by experience with different sizes in the past.

    Ballast is the rocks or gravel in between the sleepers of a train track. Adding ballast to your tracks is a really good way to help blend it into your scenery and add a sense of realism. The problem with using lots of little stones and gravel is that they're going to go everywhere! Adding ballast is a personal thing depending on your scenery.

  • Ballasted railway track: reducing maintenance needs

    17-12-2008This is because as the ballast layer tends to deform, the grains are restrained by tension generated within the fibres. However, the biggest benefit in the tests carried out in the SRTF was obtained by reducing the slope at the edge of the mound of ballast on which the track sits (termed the "ballast shoulder").
