At a recent club discussion on additions to the signalling system, various methods of control were mentioned. All of the ideas involved a considerable amount of cables and trunking that amounted to nearly three-quarters of the total cost of the installation.

One method that was not discussed – it was in fact an afterthought – was the idea of remote operation by radio control. It would seem that RC could have a number of advantages, although overall cost may not be significantly different. Signal heads, regardless of type, could be self-contained and removable, thus minimising the risk of vandalism or attack by vermin etc, plus of course much reduced exposure to weather. Being self-contained only small rechargeable batteries would be required as power supply.

My query is; has anyone used or experimented with, or even thought about such a method of control? Food for thought, anyone?
