Mine and my families favorite Action car is the Lionel 3376 Bronx Zoo Giraffe car. When my young daughter saw this car in action at a train store 30 years ago we had to get one. Now we have a string of five giraffes ducking and popping up when going thorough our various bridges and tunnels. Most were picked up as car shells needing replacement giraffes.
Giraffe cars are inexpensive, easy to find used and it is easy to install tripping rails along side the track. They take no wiring or switches. I make mine out of old slats from discarded window shutters by rounding the ends to allow tripper arm to engage.
My seven grand children also love the giraffe cars the best and they are always on the layout ready to perform.
Let us see your favorite Action car.
