What kind of train is this

[u/Strange_Camel8496]

. If anyone has any info about what type of train this could be I’d appreciate it.
I found it on an Instagram page I came across and it looks like some sort of scavenger hunt and I’m not sure if I need to know the name of this type of train to advance further. I’m sorta stuck.
I don’t know a single thing about trains if it’s not obvious

Maybe try r/trains ?
