Very much appreciate everyone's post on the MTH 2091636 Operating Santa. I bought him last year for Christmas with no instructions in the box and very disappointed he did not activate. Who knew you had to hold the button down for about 5-10 seconds? Also found out pretty quick he really leans out far almost touching the ground before returning.
Lionel's 36729 Animated (signalman) Caboose, which is much smaller in size, operates without prompt periodically activating and returning.
