You might be thinking that these are the same drawing posted twice, but in fact I made them on separate recent train trips to Montegrotte Terme and to Padova. I have similar ones from lots of other trips, but two are enough. Veneto regional trains don't have too much variation.
On the blog are earlier posts of drawings that I made on train trips to Verona and to Saint Petersburg (Russia), and then there are some of my airplane drawings too. When I was a student at the High School of Music and Art in New York, we had homework assignments to draw on the subway, so drawing on trains comes pretty naturally to me.
