The train is a dead dinosaur and time to put it to rest. Unless you can increase its speed, get rid of it.
The train tracks — pull them up and recycle the steel. Make the old trestle grade into a bicycle track so people can ride from one end of the Island to the other and just maybe, this is going out on a limb, during the Olympics this bike track can be used as a competition speed racing bike track where people all over the world can compete on it.
Seriously, quit wasting time and money on an old piece of junk. I think we need to start imagining a brighter tomorrow instead of a backward past and the train is just that. Bury the old beast.
