Help understanding these 2 sentences


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...




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'](https://en.wikipedia.org/wiki/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.'_
