==Fleet Numbering==
The car numbers of the trains range from x201 to x238, where x depends on the carriage type.
*The first digit identifies the position of the car from the closest end of the train; where ‘3’ represents first car, ‘1’ represents second car and ‘2’ represents third car.
**(Example) Passenger Vehicle 237/238 would consist of 6 cars with serial number 3237, 1237, 2237, 2238, 1238 and 3238 respectively.
*Depending on the direction of travel, the sequence may be reversed.
