Finally one late train from Kanchipuram. Thank u very much to SR railways. I requested the same in blog
/blog/post/740435/176 months back. Finally got almost same. Now its much easier start late to see Kamakshi amma and come back. Actually temple opens at 4 pm only...earlier last train used to be at 5:30 pm only...So if we have big Q normally it used to take huge time. Now some what better as last train now at 19:10.
