A BKR (Burdwan Katwa Railway) ticket issues on 7th Jan 1905 from Kamnara to Burdwan. This has BKR printed in black on the reverse. Another one of the rare railway ticket. All the tickets belong to lesser known railway companies. What I need to find out is, if these railway companies continued to issue tickets post their amalgamation with the larger railway companies or were they still independent at the time of these ticket issuance. Any help from IRFCA'ians is welcome.
