Absolutely. The principle of signalling is only one train in one one block at any time.
There is a posibility though that the signaller incorrectly authorised one of the trains to pass a signal at danger. One of the initial reports by a passenger stated that the train which normally has to stop and wait for the line to clear, slowed down on the approach to the single line but then carried on.
In this country the signaller couldn't authorise a driver to just pass a signal at danger at the entrance to a single line. Because this is 'degraded working' the instructions require a pilotman to ride with each train - and he/she acts effectively as the Single Line Token.

There's a hint in the Beeb article of some human wrong-doing, and not adhering to the rules.

Strange. The German psyche is based very much on obeying rules - and I mean that with respect.
Hope this helps.
