I love trains whether it be local rail or something more national/ long distance.
I regularly take Amtrak when I go up to Sacramento or down to Santa Barbara.
I've been on subways all around the world as well as bullet trains. From Eurostar between London & Paris, to Frecciabianca in Italy to even the Shinkansen in Japan. I've even taken -still currently the fastest operating passenger train in Shanghai- the Shanghai Maglev.
