Help understanding these 2 sentences

Question

I have trouble understanding these 2 sentences below...
Note: There is no further context provided.

1. 発車{はっしゃ}のベルが鳴{な}っているので飛{と}び乗{の}ったら、反対方向{はんたいほうこう}の電車{でんしゃ}だった

My attempt: Because the departure bell is ringing, if you hop (to the train), you will get into the opposite direction.

The sentence doesn't make sense to me... :(

2. 就職{しゅうしょく}試験{しけん}の結果{けっか}の連絡{れんらく}だと思って急いで電話に出{で}たら、間{ま}違{ちが}い電話{でんわ}だった

My attempt: If you are thinking about the notification result of the employment examination while make a phone call in a hurry, you will end up with calling a wrong number.

I'm not sure if I understand 急いで電話に出{で}たら correctly. Since isn't make a phone call "電話をかける"? But it would be strange to end up with a wrong number if you were receiving a phone call...

Answer 1

For both sentences, you can translate the 「〜たら、……だった」 as 'it turned out to be ...'

Also, both of the 〜たら have the meaning 'when', not 'if'.

発車のベルが鳴っているので飛び乗ったら、反対方向の電車だった

• 発車のベル 'the bell announcing a departing train'
• 飛び乗る 'to hop onto (the train)'
• There's a missing subject. I'm translating it as 'I' barring further context. The 'generic you' as you translated the sentences with is incorrect because it's specifying a one-off event.

'I hopped onto the train because the departure bell was ringing, and it turned out to be the wrong train (going into the opposite direction).'

2. 就職試験の結果の連絡だと思って急いで電話に出たら、間違い電話だった

• 就職試験の結果の連絡 'a phone call announcing the results of ...'
• 電話に出る 'to answer the phone'
• Another missing subject. Translated as 'I' again.
• 間違い電話 'it turned out to be the wrong number' (someone called your number mistakenly)

'I thought someone was phoning the results for the 就職試験 and hurried to the ringing phone, but it turns out it was a wrong number.'
