Using Locks on Switches While Operating

[Sumpter250]

At the Lake County Model Railroad Club, on open house days, having locks on the switches, would have prevented a number of "incidents" cause by the accidental throwing of a mainline switch, by one or more of the guests. Other than that, it would have been more of a bother, than a benefit. We've had to spike the throw rails of some of the switches on the modular layout at shows, because "fingers get playful when no one is looking". I, personally, would not be inclined to lock the switches on my home layout.
