In the scenario presented, when approaching an uncontrolled intersection, do you have priority over the rail vehicle travelling from the opposite direction to the left?

Why?

At a junction of roads with equal priority, a tram has priority over a car regardless of its approach direction. You must therefore give way to the tram shown even when it approaches from the opposite direction and turns left.
