The Railways proudly announces that senior citizens will be provided with lower berths when requested. But my experience shows that this is an empty promise. During the last two months, I have travelled by train several times. But except on one or two occasions, I always got the upper berth, even when booked sufficiently in advance.
Today also I got only upper berth.
The difficulty of senior citizens to climb to the upper berth is to be considered while allotting berths.
