電車

How it works

The subject 電車(でんしゃ) (train) comes first with no particle — in casual speech the marker is simply dropped. The verb 来る(くる) (come) shifts to plain past 来た(きた) (came), no polite ます (polite) in sight. The final よ (you know) is the punch: it flags fresh news the listener may not have noticed yet — “the train’s here!”
