Thanalan - train tracks... what are they for?

It was back in the 1.0 forums, but they definitely said it, if I have the time I will scour the archives.

id love to see doomtrain incorporated like the odin/behemoth fates need more fates like those 2 ;/

Its actually an easter egg. If the Server Time, Eorzean Time, and Local Time all hit 12 am midnight you will see a ghost train and will have to suplex it in order to beat it.
