Vehicle Location

On any sizable layout there are bound to be places where moving vehicles are out of sight. In these cases it would be very useful to have some way of keeping an eye on them. If there is some form of automatic control, such as a computer, then this will probably need some feedback on vehicle location too.

I have experimented with both reed switches and Hall Effect switches and have opted for Hall Effect switches as they best suit my needs.
