If you happen to be lucky enough to have a model train that reaches age 100 and it is still capable of running, then you might consider taking it for a birthday outing. This video shows an Ives Passenger Set #691R (with Electric Reverse), made in 1924, running a double loop track configured to look like the number 100. The train not only runs forward through the layout, but also backs up to be ready for another 100 years. The Patented Reverse Mechanism was used essentially in its original form for over 40 years.
