But I was more interested in how they handled the escape of someone in a wheelchair. It appears so easy when we are ready and prepared for such an eventuality.
I cannot help thinking, 'Why can't we think of something that is simple and practical for use at railway stations with high pedestrian crossings, for the benefit of the old and disabled?'
I am sure there are many ways to do it. For example, the hydraulic lift which can lift up a car for repairs - surely we can have one that can handle lighter weight for much cheaper without sacrificing safety. All we need next is just an opening to the existing pedestrian crossing over the double-tracking railway lines and a similar opening to another hydraulic lift at the other end.
A more primitive and much cheaper version which was actually used some where else for some other purpose, was to have a simple water container on each side with a platform for a wheelchair or two. The system works by opening the water outlet from one container to the other, which in effect raises the platform to the required level!
But of course, I reckon these are so third world and too cheap for our country!
