The Station Master uses several Telephones for different communications for the purpose of smooth Train Traffic Movement in a Station. Practically, it becomes tedious to attend to the Telephones spread over the Station Master’s Table.
The Station Master Control Console using Micro Controller, designed and developed by EPSILON enables easy and convenient operations by the Station Master / Assistant Station Master.
This Unit enables communication in :

A. 4 WIRE MODE (IRS:TC-60/2007)
I Section Controller
II Traction Power Controller
III Traction Loco Controller
IV Other Controller
by pressing the designated Push Button Switch out of the 4 Controllers.

B. 2 WIRE MODE (IRS:TC-80/2000) OR (IRS:TC-79/2000)
For Point to Point Communication between:
(i) Station Master & Assistant Station Master
(ii) Station Master / Assistant Station Master and LC Gate
(iii) Station Master / Assistant Station Master and Yard/ Maintenance etc.
A 4 x 3 matrix keypad is provided for selecting the required Slave.

C. AUTO MODE
Keep the Push Button Switch provided on the Front Panel for selecting the BSNL or RLY. The Station Master also can talk to Auto Telephone Railway and DOT by pressing the Push Button marked RLY/DOT and provided on the Front Panel and by dialing the desired number.
When a Call is received from any Auto Telephone, the respective LED shall glow. The Station Master can press the respective Push Button Switch and attend the Call.
The Unit shall consists of the following :
1. One Handset with Press to Talk (PTT) Switch to be used only in 4 Wire Mode, kept on the left hand side of the unit. Another Handset for use with 2 Wire Intercom or Auto Telephones kept on the right hand side of the unit.
2. Cradle Switches.
3. 4 Nos. of Push Button Keys for Communication between Station Master and Controllers marked CONTROL I to CONTROL IV with LED indication provided beside.
4. 5 Nos. of DC Buzzers and 2 Nos. of AC Ringers.
5. Keypad (3 x 4 matrix) for the Selective Calling Telephone and Auto Telephone.
6. A Push Button Switch to select 2 Wire Intercom or Auto Telephone.
7. Two Push Button Switches for connecting to Auto Telephone. Two LEDs by the side of this Switch indicates connection to Auto Telephone.
8. A Push Button Switch to select up or down.
9. A Ringer Circuit with Ringer for ringing in case the Station Master is called on the Auto Telephone.

OPERATION :
4 WIRE MODE :
The Station Master can call any of the 4 Controllers by pressing the assigned Push Button (Enabling) and by pressing the Press to Talk Switch in the handset, the Station Master can converse with the called Controller. After conversation, he can press the same Push Button Switch again to disconnect (Disabling). Similarly when a Controller calls the Station Master, the designated LED shall flash and the Buzzer shall hoot. The Station Master has to press the called Push Button Switch to receive the Call, the Buzzer shall stop, LED shall change from flash to steady. Press the Press to Talk Switch and the conversation shall be through.
At a time only one Controller can talk to the Station Master.
When another Controller calls the Station Master, when the Station Master is already in conversation with the first Controller, the Caller’s LED shall flash and the buzzer shall hoot. The Calling Controller shall get the ring back tone. In case the Station Master feels that the call of the Second Controller is important, he should press the Push Button of the first Caller to disable and then press the Calling Controller’s Push Button Switch for communication. After the conversation the same Push Button shall be pressed again for disabling. Similarly the Station Master can have communication with any of the 4 Controllers, using only one Telephone Handset.
The 6 Wires coming from the 4 Nos. of 4 Wire Decoders are terminated inside the Unit as per the Standard Wiring for Cradle Switch /+12, -12V / MIC / REC / BUZ / PTT / LED.
Thus this Unit replaces 4 Control Telephones as per IRS:TC-38/97.
2 WIRE MODE : Press the Push Button Switch to 2 WIRE
The functions are same as Desk Type 2 Wire / 12 Way Selective Calling Telephone as per IRS:TC-80/2000 or Electronic Magneto Telephone as per IRS:TC-79/2000. In this case the Press to Talk Switch need not be pressed for talking. However after conversation the Handset should be kept on the ‘Cradle to disconnect or press the Cradle Switch manually to disconnect’. The LED provided and a Buzzer shall be activated when any of the Slave Telephone calls the Station Master. Press * for Selective Calling or Press # for Magneto.

AUTO MODE :
Whether the Push Button Switch is in AUTO Mode and when the Push Button Switch marked RLY or DOT is pressed, the Station Master gets connected to the respective Auto Telephone. AC Ringer and an LED provided in the Unit shall ring and the LED shall glow whenever there is a Call from the Auto Telephone. To attend the Call, the Station Master has to press the Push Button Switch marked ‘AUTO’. After the conversation, the Station Master has to press the Push Button Switch again to normal position. In case the Station Master wants to call any Auto Telephones, he has to press the Push Button Switch marked RLY or DOT and dial the desired number using the Keypad Switch. He can set the Push Button Switch to 2 Wire or Auto Mode as per the requirement.
FOR BETTER CONVENIENCE OF OPERATION, OUR FINAL DESIGN IS IN 2 PARTS FOR 4 WIRE AND 2 WIRE AND AUTO MODES.
D. DIGITAL CLOCK - 6 Digit LED Type RTC/GPS Based.
This shall indicate the time based on Real Time or GPS.
The Station Master Control Console works on 12VDC and the maximum current consumption shall be 600m Amps.
As per latest version, the 2 WIRE MODE is kept as a separate unit with UP and DOWN Calling Indication.
