without modifications.

Runs on 3 V power supply or DC source of 6 to 60 V.

The system provides a reliable and convenient wired link for the railway station master to communicate with outdoor crew and drivers of arriving trains. It also enables the station master to monitor the sounds of running trains and activity at the outdoor location.

The system consists of two devices; an outdoor unit known as a Signal Post Telephone or SPT and it's indoor pair called the Station Master's Console or SMC.

Voice is conveyed by loud-speaker - microphone. The communication system is semi-duplex. A single pair of dedicated wires between the two units suffices for all functions of the system and power supply is required only at the station master's unit. No power supply is required for the SPT.

Complies and surpasses RDSO Specification TCA 3352.

The SPRINT Kit assists in the safe, reliable and efficient performance of magneto telephones at critical railway locations.
It teams up to provide the magneto telephone with:
1) An efficient and dedicated solar based power supply with back-up;
2) Surge protection for the communication line;
3) Sensitive high impedance powered ringer with terminals for a parallel unit;
4) Connection terminals with selector switch for a spare magneto telephone

The system consists of a Master unit communicating with up to 10 Remote units.

Connections are by a single pair of wires from the Master unit to each Remote unit separately.

The entire system works on 230V AC fed to each Unit at their respective locations.
