Mika on rails 
After years (last time I visited it was in 2018 or so) I remembered again that this delightful website maintained by a japanese artist exists featuring all sorts of cute train icons from all over the world: http://trainfrontview.net/sozai-db2.htm
Dr. Sobek@Sobex Yeah those pages are also very cool. The network maps featured on the individual pages to show where the trainsets run are a bit of a sin though haha
