>>8591295I did not find anything but train (choo choo not training) can mean "group of objects" even though no one says it like that. People from that region adapted the "group of objects" into "thing" so they insert "train" into every phrase. I could be thinking too much and they just like to say train because it's the only state with trains. I forgot another thing I was going to say but tldr train=thing there.
