Ghost of the Railroad Engineer:
It is as you see... we are all dead and cannot hold a hammer. When we realized we could no longer work, we started to go insane, and this is the result.
The ghost you spoke with was a good man once, and strong, so he may outlast many of us. Still, it's just a matter of time, as it was with me.
May I ask a favor of you? This is just between us...
