Time tables of extinct Narrow Gauge lines in South India from Bradshaw 1933. Kulasekharapatnam Light Railway and KPM Central-Udangudi Branch. Interesting to note that the Kulasekharapatnam Light Railway had a branch line too.
K.P.M means Kulasekhara pattinam.
During my child hood at the age of 7 to 9 yrs old, I have seen the old railway track near kulasai beach(200 mts from my house).
