In this scenario, are you still permitted to drive onto the railway crossing?

In the photo you are approaching a level crossing with half-barriers at dusk; the barrier arms are raised, but the signals on both sides are showing a red light. In this situation you are no longer allowed to drive onto the crossing. The answer is: no.

The Regulation on road signs and signals states that a flashing red signal or two alternately flashing red signals mean no entry beyond the signal or other device giving these signals. The Road Traffic Act requires you to drive at such a speed that you can stop the vehicle in a safe place when a safety device or a signal given prohibits entry onto the crossing, and it prohibits driving onto the crossing when the lowering of the barriers has started. The red light comes on a few seconds before the half-barriers come down - this is exactly the moment shown in the photo: the barrier arms are still up, but the ban already applies, just as a red light at a junction applies regardless of whether someone is already crossing from the side. "I will make it under the barrier" is one of the most dangerous decisions on the road. You stop before the signal or the stop line and wait until the lights go out and the barriers - if they came down - are fully raised.
