A: Hey there! You won't believe it, but did you hear about the big thing happening with our beloved Yamanote line?

B: Nope, what's going on?

A: They're celebrating its 100th anniversary! Can you imagine? They've got some cool old train cars all dressed up to remind us of the past.

B: Oh wow, that sounds exciting! What kind of trains are they?

A: Well, there's this one from the '60s called the 103 series, it's all light green. And then there's another one called the 205 series, which replaced the 103 and has a silver body with a horizontal green stripe.

B: That sounds neat! I wonder if I should take a ride on one of those trains.

A: Absolutely! People are already taking photos and hopping on board at Osaki Station. The station master says they have events planned all along the Yamanote Line, so it'll be a fun journey for sure!

B: Sweet! I should definitely check that out. How long will these commemorative trains be running?

A: Until early November, so you still have some time! Enjoy the trip down memory lane!
