と言うこともできます。
"The train is on its way."- This indicates to the child that the train is busy moving in their direction and will be there soon.
"The train will be here soon."- Indicates to the child that the train is not too far away.
"The train is picking up other people first." - Assuming the train is on a schedule, it has many stops. This shows the child it is somewhere else but will be there shortly after stopping to pick up other people.
"The train is on its way."（電車はもうすぐ来るよ）
→これは「電車はもうすぐここに到着する」と伝えています。
"The train will be here soon."（もうすぐ電車が来るよ）
→電車がもう近くまで来ていることを伝えています。
"The train is picking up other people first."（電車は他の人を先に乗せているんだよ）

These sentences are used to explain that when asked "why isn't there a train on the railway line?" or "where is the train?" the usual responses would be "The train's on its way" and "The train's not use yet".
'On its way' is a causal term to imply that something will be there/arrive shortly.
'Not due yet' is referring that something is coming but not at this time, you will have to wait.
"Why isn't there a train on the railway line?"（何で線路に電車がないの）や "Where is the train?"（電車はどこ）に対する標準的な返答は、"The train's on its way"（電車はもうすぐ来るよ）や "The train's not due yet"（まだ電車が来る時間ではない）だと思います。
'On its way' は「もうすぐ到着する」という意味のカジュアルな表現です。
'Not due yet' は、それが「今」ではなく「後」で来ることを表します。待たないといけないということ。
The train is still on its way to this station. It should arrive at <time>.
The time now is <time>. The train will come at <time>.
To explain it simply, you could use a phrase such as "The train is not scheduled to come yet.". This is the easiest way to provide a basic answer.
If you wish to deepen understanding you could choose to explain a little bit further using sentences such as "The train is still on its way to this station. It should arrive at <time>." This helps the child to understand why the train is not there yet and grasp the concept of how a schedule applies in practical terms.
You could even turn it into an opportunity to practice some maths! You could either ask or tell the time now, then explain the time the train is scheduled. "The time now is <time>. The train will come at <time>." Then ask the child "How much longer until the train will come?"
シンプルに説明するなら、"The train is not scheduled to come yet."（まだ電車が来る時間ではない）などと言えます。これが最も簡単な言い方です。
より詳しく説明したいなら、例えば "The train is still on its way to this station. It should arrive at <time>."（電車は今こっちに向かっている。〈時刻〉に来るはずだよ）などと言えます。これで、なぜまだ電車が来ていないか、そして、スケジュールとは何かについても子どもに教えられます。
算数の練習にすることもできます！今の時間と電車が来る予定の時間を伝えます。
"The time now is <time>. The train will come at <time>."（今は〈時刻〉。電車が来るのは〈時刻〉）
そうしたら、"How much longer until the train will come?"（電車が来るまであと何分）と子どもに質問しましょう。
