Fleet Numbering

The car numbers of the trains range from 841x to 864x, where x depends on the carriage type.

• The last digit identifies the position of the car from the front end of the train; where ‘1’ represents first car, ‘2’ represents second car and ‘3’ represents third car.
  • (Example) Passenger Vehicle 50 (also 850) would consist of 3 cars with serial number 8501, 8502, 8503 respectively.
• Depending on the direction of travel, the sequence may be reversed.
