One thing I noticed in Kalka mail was how rugged and worn off its coaches are (almost all). With 1996 date made coaches (20 years) HWH as I find is notorious for using so old and rusty coaches for all popular trains running daily be it Kalka, Mumbai mail, Chennai Mail/ Coromondel. It is so weird that we talk of flagship industrial programmes but our manufacturing is yet to be at par with needs.
