There is actually no reason! 220V, 110V, 24V all are available voltages. India was once a British colony and hence, the power system started with the standards the British were following during their time. Now if we change, the existing power plants will become useless. Hence, to maintain continuity, 220V 50Hz is being used.
The Indian Railways power outlet works in 110 Volt, almost all electrical control systems are designed for 110 Volt or 24Volt.
Ideally, the safest voltage to use is anything under 24 Volt AC, like 12VAC, 5VAC. The lower the better, as it will lower the chances of getting electrical shock, and consuming less power.
Anyways, just as a matter of fact, more work can be done for less power using 60Hz than 50Hz (energy remaining constant).
