Love trains? Love Union Station? Love actor Taye Diggs? Head down to Union Station on May 8 between 11 and 4 for National Train Day, Amtrak’s annual celebration of trains and rail travel. There will be exhibits and performances to see, you can check out various trains and model trains while you’re there, and National Train Day spokesman Taye Diggs will be on hand. Want to take a tour of the trains? Reserve a free ticket ahead of time. No word on whether Taye will be leading tours himself, but if he is… sign me up!
