…without getting too animated about it.
As a general rule, so the thinking goes, toy train lovers like animation and scale rivet counter types only want the trains themselves to be animated, following the pattern of trains being the actors on the stage and everything else detracting.
Probably it is a general rule, but there are some exceptions. For example, I went with a buddy to an NMRA open house, viewing an HO and HOn3 “scale” layout. The owner had scratchbuilt just about everything including a dozen or more animation devices including an elaborate coal conveyor that actually transported coal from mine to coal car and then later at the power plant, a coal dump; operating bridges; an engine house with remotely controlled opening doors, a Faller car/truck system that worked remote control, and much more. And furthermore, he actually used all of the animation, starting the train from the mines and ending up at the plant and having a narrow-gauge exchange that had animation as well.
At the other end of the spectrum, is a nearby toy train layout that I visited. It had all of the “required” animation such as the ice plant, milk barrel, coal tipple and about 20 other items you can find in catalogs, as well as some PW animation.
While I was fascinated with the trains, I was equally fascinated with the toy train animated accessories and had him operate each one. He obliged and then commented that he never much uses the animated accessories and instead, prefers to run 4 or 5 trains at once, all at high speed, and kick back and watch.
Both approaches, of course, are valid from the model railroader’s perspective and we should not denigrate either approach.
Personally, my view is that the more animation, the better, and that instead of detracting focus from the trains, animation makes a harmonious environment between the moving trains and the bustling scene around them.
If it were up to me, I’d even like to see programmable miniatu
