At time of writing, 59% of trains are delayed. I have very fond memories of train travel in India. I learned a lot about relaxing, and going with the flow.
It also has to do with punctuating the journey with many small stations and always being added halts.
As a railway brat, I miss long distance train travel like crazy.
a 36 hour journey from Chennay to NJP in a Sleeper.. This is India.)
When I was a kid and used to go on vacation with family, the late train was so good for me. It meant few extra vacation hours before schools and homework would start. I hope it would become the same again. BTW, only my lifestyle has changed. Train timings are still there where they were 15 yrs ago or maybe have become "more relaxing" :-)
