Or, here is what I do every once and a while: Play "where will it go?"
I get a nice glass of bourbon, go downstairs, put one long train on the layout, and then randomly set all of the switches. Then I turn on the power, set the throttle on low, and just sit back and watch the train meander around the layout, while I sip my drink. It is very relaxing. I never know where the train will go or end up.
