Not quite SE Asia, more like NW, but have look at Peshawar, a main line right across the runway. We avoided straight in approaches like the poison, didn't give us chance to have a good look around for choochoos -- NO traffic lights, and no "rule" as to whether trains or planes (in our case PIA B707) had right of way.
I guess inshallah was the official policy.
Tootle pip!!
