Not only oil, also short on people to drive all those trains and busses (people who accept low wages, of course).

I meant that driving trains doesn't require oil, while people driving cars does. Hence your country is bleeding capital every time somebody drives.

The whole train infrastructure is very self sufficient in Germany and they indeed export trains and tracks and all associated technology all over the place too, hence the term "oversufficient".

Wages are quite good especially for the low skills/paid training

Bus drivers are not paid very well in Germany. Especially those who work for relatively small private companies.
