Swedish Moose Test

So did you ever contemplate being a subway driver on Stockholm's famous Tunnelbana? OK, here's lesson no. 1:

On (normal road) intersections, the public transport signals (i.e. those used for streetcars or buses) are wired just like standard traffic lights, just to prevent motorists from confusing them with their traffic lights, instead of a red light they display an "S" (stop), and a horizontal and vertical bar for amber and green, respectively.

Imagine the platform being between the two tracks, and one one end of the platform you have a level crossing for travellers wishing to exit this way.
The exit signal guards the next block, and the level crossing is guarded by a signal of the type that is standard for public transport.

Since the two signals are not interlocked, you may meet any of the following aspects, please answer the question in which of these situations you may proceed:

Halt, Fahrt frei The block signal shows red while the crossing signals indicate that it is safe (for the train) to pass the crossing.
Halt, Halt erwarten The block signal is still at danger, while the crossing signal displays the equivalent of a street stoplight showing amber: Prepare for red.

Halt (jetzt aber wirklich!)

Now both signals show stop.
Fahrt frei, Halt! The previous train has cleared the block, so the signal shows 'clear'. Since the same aspect (i.e. clear) is shown to the pedestrians, the streetcar signal is still at "S" (i.e. stop).
Fahrt frei The block signal is still at clear, and the streetcar signal shows a vertical bar, equivalent to a green traffic light.
