SUPER RARE!!/WEIRD!! Blue Admin Train Encounter / Subway Testing Remastered ROBLOX

DISCLAIMER
I did not know this was a mod when I shot the video, please disregard the text.
I was recently playing Subway Testing Remastered and I encountered this weird blue train. I never seen this before and I wondered hoe it got in the game in the first place. The driver was flying with a cape and had a MTA shirt on. This is by far the weirdest and rarest encounter on Subway Testing Remastered I have ever seen! The whole thing is a big mystery. If you think you know what this is, please comment below.
