For several weeks now, besides running my layout during the day, I been turning the overhead lights and all room lights off and then turning all the layout buildings, pole lights, etc. on. Seeing my engines coming down the tracks with only the headlights and tail lights of the caboose going through the countryside with only crossing light flashing as they cross roadways. Coming into town and the lights of businesses, stations, etc. illuminating the train cars. Passenger trains seem to be more alive as those riding can be seen more distinctly though briefly as they pass by. Being able to see the switch lights I can switch tracks and trains without problems.
Seems night running has increased my fun in running my trains
