"The Past, Present and Future of Travel"...

Comments welcome.
Some of you may be curious about the inner rails. Those inner rails are referred to as "guide rails" or guard rails. Used often on bridges, they will limit how far sideways the train's wheels can travel in case of a derailment. They basically keep the wheels on the ties and track at least until it has left the bridge.
