お忘れ物ですね。時間と、もし覚えていれば何両目に乗られましたか？
おわすれものですね。じかんと、もしおぼえていればなんりょうめにのられましたか？
A lost item, correct. What time was it, and if you remember, which car were you in?
Gesture & etiquette
Mimic holding an umbrella then forgetting it.
Be as specific as possible about the item, date, time, and train line. Avoid being vague.
