Never !! Just finished a session and will run more later. Had my "early" train running, everything is 1945-46 runs smooth.
Not at all. I need more time to run more trains!

I do get "burned out" from time to time, but I always come with more enthusiasm than ever.

Having trains in various scales and gauges to play with, boredom is never a problem!
Happy Rails!

I've discovered that I only run - operate - my trains (during the past ten years, approx.) when we have company that has requested seeing them. Otherwise, my attention and enjoyment have shifted to crafting narrative vignettes for clients and customers' layouts.
Oh, and did I ever mention, I completely re-crafted several whole swaths of scenery on my own layout?

For many people, running a train and watching one run around can be boring. What I try to do to make it more interesting to run and also more interesting for the people to view it, is to construct the layout with different loops. In other words, I use a lot of switches to have the train go through one pathway, and then another, and another. I rarely use my switches just for idle turnouts to park cars, etc. This makes it more interactive for me and much more interesting for spectators. Another thing I do is intersperse my old Lionel operating accessories throughout the different loops with many remote controls and insulated track. For example, the crossing gate may be on one loop, the gateman on another, and coal loader on yet another along with the platform for the operating milk car. I do have my operating cattle car by itself on a turnout simply because of the inconsistency in its operation had it been moving previously to loading/unloading. Once I have it set perfectly (including the shoes touching the appropriate portions of the track), I don't want to disturb it. The other thing to counter the boredom for oneself is to constantly refine the layout. Now this has nothing to do with the actual running of the train, but adding to the landscape and changing the rolling stock (even through the use of turnouts and remote controls while it is running) can make it more interesting. For me, the constant refinement is a process that I enjoy inasmuch as I do not believe any layout is ever "finished." Another thing I do to make it more interactive for spectators is to place accessories like the barrel loader and coal dumping area close to the front, so that they can place the barrels back on the loading space or put the coal back into the dump car. At one time, I had those accessories fixed to a small transformer in the front with switches for the various accessories so that the spectators could actually control them, but that became somewhat problematical.
