Alstom Metropolis C830C are the second generation of trains running on the Circle Line. These trains were manufactured from 2014 to 2015 by Alstom Transport under the Contract 830C.

History

Alstom Transport was awarded Contract C830C in 2012 at a cost of $134 million for the construction of 72 passenger cars.[1]

Faulty Equipment

Passenger Vehicle 46 suffered from a faulty signalling hardware, resulting in intermittent signaling issues which caused widespread disruptions to the Circle Line for a week in both August and November 2016.[2]

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.
