Hello, I was considering Backmann's  Model #90076 (White Christmas Express) as part of my store's holiday window display as I have been wanting to display an operating train in the window for years. My question is will running this particular model for 8-10 hours "nonstop" have adverse effects on the motor or transformer? Any recommendations for what I'm wanting to do...I already opted NOT to get a battery operated version! Thank you for your insight....Bill
