Because there are not enough mechanical replacers kicking around these days?

For a wire operated signal, getting the wire to the post from the track would not have been easy. I'm guessing it would have required a brick lined well/manhole in the platform for the signal post together with a wire crank or wheel at its base. Much quicker/easier and cheaper to run a cable to a signal planted on the platform.

Perhaps because it would be too easy to tamper with?

Is that often a serious consideration?
Most signals would not be particularly difficult to tamper with, but not many of those who are malicious inclined have enough know how to do more than to cause a fail-safe fault. Is there much vandalism at that location? I have always felt that the presence of a manned signalbox is likely to be a deterrent to that sort of thing.

Signals on platforms usually have some protection to separate the public from moving parts for the protection of both. Electricity simplifies things.

You may all be interested to know that the old OB30 signal, with a nice 1940s LNER steel bracket, has been preserved by the NNR and will be rebuilt into a new Sheringham Down Home signal. The signal will have a main arm on the left hand (for the main route) and a small shunt arm (for running into the loop). Credit due to various folks within Network Rail who made its procurement a very easy process.
