I smell a case!

The Case of the Ghost Train!

As for summon as we seen back in Hildibrand Season 1 and Alexander the summon can happen unintentionally as well which we see when a Fake Enkidu was summoned by Gilgamesh and from explanation about how Alexander was summoned.

A Ghost Train story may be enough spark to cause a unintentional summon of Doom Train if enough people started believing in a Ghost Train Story strong enough.
