i was just wondering if your robot pfp is based on any train? it reminds me of the Alstom AGV, but i could be very off, so idk

Thinking about it in retrospect, it would have made total sense for me to have used an anthropomorphized train as the pfp of my train posting accounts. Probably would have one of a train of the Nederlandse Spoorwegen. When I created a bunch of new accounts so that I have separate accounts to post train pics on, I decided to use my synth dragon OC for that:

I can see why you might have thought it was based on a train, as red on black colour schemes are quite commonly used in the world of transit. Like for example the R-net livery:

QBuzz GTW 2/8 number 6357 at Dordrecht train station. Nederlandse Spoorwegen has a few trains in this colour scheme too:
