These were but temporary stations; 31 Company was to serve the 1st (Peshawar) Division at Rawalpindi and Murree; 32 Company was to take over the Central Signalling School at Kasauli; Quetta was to be the station for 33 Company serving the 4th (Quetta) Division; the Central Signaling School at Poona was to be taken over by 34 Company which, however, remained at Ahmednagar and conducted the Signalling classes there; 41 Company was to be located with the Cavalry School at Saugor.

The Corps of Signals is presently organised into Officers and JCOs/OR. Unlike Officers who are employable at all aspects viz Communication, Administration etc, the other ranks are organised into various trades like TES/TER (Technician Electronics and Systems/ Technician Electronics and Radio), OCC (Operator Communication Console) etc. The other ranks are employed only within their respective fields. The Corps is organised structurally into various regiments and companies. Each Brigade has a Signal Company commanded by a Major/ Lt Col associated with it, while Division and Corps have a Signal Regiment, commanded by a Colonel. The Corps of Signals has the privilege of being the EW (Electronic Warfare) arm of the Indian Army with a vast array of computerised / automated state-of-art systems.
