Connection between Castrum Meridianum and Phantom Train?

Three years into this game and I only noticed this tonight as I land in CM for the roulette. I get seperated from group (through my own fault), pop open map and see the area label "Phantom Train Depot". Now, I used to think the tracks were basically some trolley/mini-transport train the Garleans were using but I'm wondering if there was more to it.

Could some loremasters share some light on this? Maybe there's something in-game that I don't remember or missed out about it--and yes, I'm aware of the raid version of it but I don't think it mentioned anything related to the Garlean Empire (or maybe it did, can't recall).

The Phantom Train in FFXIV is a train used by the Garleans to transport troops and supplies between castra. It is called the Phantom Train due to the apparent secretive nature of its route/schedule/whatever.

As Wyssahtyn said above, it's simply a label the Garleans used to describe their secret military railway they built between Castrum Centri in Mor Dhona and Castrum Meridanium in Northern Thanalan (the military term 'ghost' refering to something secret or out of sight). It has zero connection to FFVI's Phantom Train that appears in the Omega raids (which is an actual ghost train).

Oh

*excitement deflating*

okay

According to Yda, it's also really unpleasant to stow away in.
