In this situation, do you have the right to overtake the vehicle in front of you by driving onto the part of the road designated for oncoming traffic, if you can stop before the railway crossing?

Why?

The photo shows a car waiting at lowered barriers with red signals illuminated. You must not pass a vehicle waiting for the crossing to reopen if doing so requires entering the part of the road reserved for oncoming traffic. Being able to stop before the tracks does not make this manoeuvre legal.
