I did some loose math which might help in fighting the ticket (maybe math will save you!).

At 25kph, you're travelling approx 7m per second.
Average human perception time is 3/4 of a second.
Average human reaction time is 3/4 of a second.
In 1.5 seconds, you've travelled ~10 metres (that's before you've even hit the brakes).
I'm going to say that once you hit the brakes at 25kph it takes about 5m (pure estimate).
So that's 15 metres. If you can establish that you were less than 15 metres before the 5m stop line, you can safely say no average person should be expected to stop in that time.

If the crossing light was activated, and you crossed the tracks within 2 seconds at 25kph, that means you were within 14 metres of the tracks themselves.

I think there's a camera there, so you'd have to be sure you were about halfway between the X on the road and the stop line for that to hold up.

Now, I also failed math in highschool. So this could basically be useless.
