Sorry to be a pain on the 1.5 times the braking issue. I may be slow here, but from my reading of the GK/RT0075 standard, I can't seem to see where it says it's OK to exceed the min braking distance by more than 50% for mixed traffic on the same line. However, as pointed out, I guess this is one of those problems that arises in the exam because the deceleration rates for passenger and freight are equal, and this is not necessarily reflective of reality (though makes for simpler exam calculations).

I think this is covered in the exceptions in Table 1 entry d on page 10.
