What does BU mean in UNCLASSIFIED

Functionality

BU has two basic functions. The first function allows for precise and safe removal of ballast from beneath the railway track bed in order to level it properly. This ensures that trains run smoothly along the track without any obstructions or obstacles. The second function is to create a level ditch around the track bed so that when new rail ties are laid down, they will sit evenly without requiring further adjustment or work. Furthermore, BU can also be used to cut through existing rail ties when they need to be replaced due to wear and tear or any other reason.

Advantages

The most prominent advantage of using a Ballast Undercutter is its speed and precision which enable quick turnaround times during engineering works and construction projects. It removes ballasts with greater accuracy than manual labour would, ensuring that no stone remains left underneath the railroad tracks even in hard-to-reach areas like curves and slopes where manual labourers usually struggle to reach them. Additionally, by creating a level ditch around railways, it reduces the amount of time it takes for tracks to be fully covered with new rails since there's no need for further adjustments or levelling before laying down new rails on top. This improves overall efficiency during construction works as well as minimizing costs associated with such projects due to less labor being required as well as quicker completion times.
