In some cases the first two digits may represent the year the coach was transfered to the zonal railway, and sometimes the year represented is the year

How do signals refer to specific lines in the case of diverging and converging routes?

Multiple signals may be mounted on a signal assembly (bracket post, signal gantry, etc.) to provide signal indications for diverging routes. The signals from left to right correspond to the diverging routes from left to right. If one of the routes is the main line, the signal for it is usually placed higher than the others (the maximum permissible
