Public transport is great for magic
I wrote something similar here a while ago. But on public transit I practice my double lift over and over. For example a three hour train is three hours of working on it (alongside other stuff too).
What I've found is on almost every train I get someone notices and asks to see a trick. From there I end up performing to groups etc.
Maybe this is just a UK thing because people generally can be social on trains here. But yeah, I love train magic!
