In 1967 the Economic Commission for Asia and the Far Est (ECAFE, then ESCAP) of the UN supported a proposal for a trans-Asian railway linking Turkey with India and Thailand. The estimated cost for building the missing links was not even a billion dollar. DB director Friedrich Loehr however found, that nearly 20 billion were necessary in order to make it competitive for freight traffic. Re-opening of the Suez Canal in 1975 made the proposal unrealistic.
