Hello everyone, I am turning to this forum in hopes of getting some help before Christmas time. I have a completely enclosed in plexiglass outdoor model railroad Christmas display.I have run 5 trains and a trolly for the last two winters outdoors.They run anywhere from 4-5 hours a night with only minor problems. But the constant running of the engines for an extensive amount of time per night has caused some engine breakdowns. My solution to this would be to install some sort of push button controls with timers that would allow the kids to walk up and push a doorbell type button and allow the trains to run for a set period of time. Any help with this topic would be great. Trying to get it retrofitted to put out for Christmas. Thank you looking forward to any help.
