Today we went on the oldest subway on the continent, Budapest yellow line. It’s really old!! It’s 116 years old! The cars are yellow, just like the blue line cars are blue. Speaking of cars, when the doors open, they make this terrific crashing noise as they bang into their places, when they close, and to warn people not to get on any more, a red light turns on above the door and a loud buzzing starts. It reminded me of some robotic emergency. Bye!
