Train classification is the process of organizing and categorizing trains based on various criteria, such as their type, purpose, or operational characteristics. This helps railway operators manage their fleets more efficiently and ensures that trains are dispatched according to their specific roles, such as passenger service or freight transport. In a typical classification yard, trains are sorted using a system of tracks and switches. Trains are divided into different categories, such as freight trains, passenger trains, and maintenance-of-way trains. This systematic approach allows for better scheduling, maintenance, and overall management of railway operations.
