South Korea tried last week to send a train into the North for a joint field study on the roads and railways... that will hopefully, one day connect the whole peninsula.<br />But it was apparently blocked by the UN Command.<br /> A Unification Ministry official says the train was turned back because Seoul failed to inform the UNC 48 hours in advance.<br />That notification didn't happen in time because talks with Pyongyang had been delayed.<br />The official didn't elaborate, but did mention... he was informed the main reason for the rejection wasn't the late notice. <br />
