Crossrail造句怎麼寫

After decades of wrangling, there is agreement at last on a fast underground Crossrail linking suburbs west and east, but this will not be open until 2017 at the earliest and the cost has spiralled.

Meanwhile Crossrail is essential in order to cope with London's growing population.

經過數十年的爭論，終於達成協議，建設一條連接東西郊的快速地鐵（倫敦橫貫鐵路，Crossrail），但是項目動工時間不會早於2017年，而且工程成本也在不斷增加。
