Systems of Working

56. Continuous Automatic Train Control System.

(1)The Continuous Automatic Train Control system of working shall be adopted on the Delhi Metro Airport Express Line for movement of trains between stations and between depot and the main line.

(2)The Continuous Automatic Train Control system works on the principle of target speed and target distance with cab signaling by means of continuous transmission from track to train through track circuits, ensuring safe movement or all trains under all operating conditions by continuously generating a safe operating envelope according to the limit of movement authority and the maximum safe speed.

(3)The limit of movement authority shall be the farthest point to which the train may safely proceed taking into account margins for error in speed and distance measurement, calculating braking distances and the equipment reaction times.

(4)The maximum safe speed shall be maximum speed at which the train is permitted to travel without intervention by the train control and signaling system and it shall be continuously calculated in such a manner that permanent speed restrictions, the speed limits for the type of train and temporary speed restrictions shall not be exceeded and the train shall always stop without passing the limit of movement authority.

(5)The Continuous Automatic Train Control system shall provide the following modes of train operation, namely:-

(a)Automatic mode;

(b)Automatic Reversal mode;

(c)Coded Manual mode;

(d)Restricted Manual mode; and

(e)Cut out mode.

(f)open train doors on the correct side when the train is docked if permitted by the Automatic Train Protection door release and the platform screen doors on the correct side open automatically;

(g)prevent the train from starting if train doors or the platform screen doors are not detected closed;

(h)train re-starting from a signal stop shall be automatic; and

(i)train starting or re-starting from a station stop shall be initiated by the train operator.

58. Automatic Reversal Mode.

(1)This mode is used to reverse the running direction of a train automatically in areas of the section specifically defined in the special instructions which are possible only at specified track circuits of a station when train is at standstill.

(2)The transition from Automatic Mode or Coded Manual mode to Automatic Reversal mode is initiated automatically upon receiving the request for reversal operation from Automatic train Supervision and has to be acknowledged by the train operator by pressing the Automatic Reversal button at standstill.

(b)determine continuously the target speed and limit of movement authority;

(c)prevent train operation in excess of the target speed or limit of movement authority;

(d)provide audible and visual warning if the train speed exceeds the target speed;

(e)enable train doors when the train is docked, enabling only the doors on the platform side of the train; and

(f)prevent the train from starting if train doors are not detected closed.

(3)If sufficient conditions have been met, the Automatic Mode will be offered to train operator for his acceptance.

60. Restricted Manual mode.

(2)The Restricted Manual mode shall be used

(a)to operate trains in depots;

(b)following an emergency brake application on main line, and absence of cab signals;

(c)for entry and exit to the depot; and

(d)on instructions from traffic controller.

(3)In Restricted Manual mode, the train speed shall be limited to a maximum of twenty five kilometer per hour enforced by on board Automatic Train Protection equipment.

(4)All platform screen doors will have to be operated manually by the train operator from the local panel provided near the train cab at the platform.

(5)The Train doors on the correct side will also have to be operated manually by the train operator.
