a weird czech 814/812-based train, contains a touchscreen likely originally intended for children's entertainment, but one of the UI options is "futanari"
image 1 is a shitty mspaint recreation of the outside using an image I found, I'm not sure if it was yellow or blue tho, the main point is that the train is pretty much a cube, but physics don't matter in dreams, right?

image 2 is the interior layout, it is more like a bus than a train design-wise
the screen was kinda widescreen, with a thick bezel, the touch was likely resistive
the UI seems to be similar to an infocenter screen, there is a long list of options, which were likely various info stuff, I don't remember any of them except "futanari", so I added a bunch of semi-random topics
unfortunately, in the dream, I didn't have time to read the options and I spent so much time looking at it I missed my stop, if I managed to click it, it would most likely redirect to the wikipedia page
sound doesn't work well in dreams, not sure if the train was diesel or battery, but more likely diesel
