Many railways have points levers positioned within easy reach of the driver when passing. How does one stop passengers from having a go too, then causing a derailment.

I don't think you can physically stop that happening. At Sheffield we avoid having point levers where they can be trip hazards or can be reached by passengers. Where the driver does have to change a (facing) point it is electrically controlled. The driver pushes one of two buttons depending on whether the train is going left or right, then a relay is activated and the pneumatic cylinder operates the point. At the same time the push buttons are disabled electrically until the block is clear, so passengers can push the buttons but nothing will happen. I'm not sure if this is feasible for your system though.

At High Legh the point switch is a trains length plus a bit before the point, so a passenger changing the point will not resut in a derailment. Still possible to do with a manual point lever.

Until recently we only had points in the station and they are controlled by a Signalman. We are just acquiring route selection out on the main circuit, when the system is completed they will be power points with automatic route selection, so trains will not stop.
