The Unification Ministry has begun thinking of follow-up measures to upcoming trial runs of inter-Korean railways with North Korea.

A ministry official on Sunday said details on the trials will begin after documents are exchanged with the North for bilateral consultation, including specific procedures, selection of staff to take part in the tests and reporting and shooting of the event.

In the next round of inter-Korean ministerial military talks beginning Tuesday, Seoul will conclude military security guarantees and communication methods needed for the tests.
