In the train number format 0xxx, which number position specifies the line of origin?

In the train number format 0xxx, the second position is specifically designed to indicate the line of origin. This system is used for quick identification and differentiation between various lines within the transit network. Each line is assigned a unique designation in that position, aiding in operational clarity and ensuring that both passengers and personnel can easily recognize which train serves what route. This structure simplifies communication and enhances efficiency in train scheduling and routing, as the second digit serves as a key reference point for the line of origin.

The other positions in the sequence have specific functions, but they do not pertain to identifying the line. The first position typically denotes a category like '0' for certain services, while the last positions may denote specific routes or train sequences within that line. Understanding this numbering format is crucial for operations and ensuring smooth transit service.
