Q. How are passenger coaches and coaching stock in general classified by IR?
Coaching stock in general is divided into two categories, Passenger Coaching Vehicles (PCV) (sometimes 'Passenger Carrying Vehicles') which are coaches that carry passengers, and Other Coaching Vehicles (OCV), which include service coaches such as pantry cars, parcel vans, mail vans, etc.
Coaching stock is classified using the codes shown below. Note that these codes are according to the structural features and used for rolling stock management. Separate codes are used for indicating the types of accommodations available in PCV coaches...
more... for ticketing and reservation purposes, etc. Those coach designations and class indications are explained in the section on travel.
Prefixes
W : (prefix) Vestibuled
Y : (prefix) Suburban
G : Self-generating (lighting by axle generators) (omitted)
E : 4-wheeled stock
L : (prefix) LHB coaches
The 'W' prefix for BG is omitted in many cases (e.g., the new LHB coaches) since almost all new stock is now BG. The 'G' code to indicate a self-generating coach is omitted for the new LHB coaches, which get a '/SG' suffix. It is also omitted in other cases.
