That freight ain't ready to leave until the conductor turns on the marker lights An old Bay Window caboose with a new toggle type switch that powers the L.E.D. marker lights and a 3 volt interior bulb. Stay away from those slide switches as they can be unreliable. A toy train becomes more interesting when lighted for "after dark" operations. The caboose normally sets square on the rails, but I tipped it slightly for the picture. All the cabooses and specially marked freight cars have Logic Rail Technologies detectable wheel sets to activate the red block signal if left on the main line while switching cars at a siding. That 16 car freight emphasizes that my yard has a bowl to keep cars from rolling out on the mainline. The camera also exaggerates the kink in the yard tracks at left. Before that train leaves, have the conductor turn on the lights to simulate a "get ready" action for train movements. In this situation, how about a train approaching from the rear, that's what the marker lights are for.
