シンガポールの地下鉄南北線は、大体'地上'のシステムです。全線自動運転のため、信号機なく (ポイント側あり)、標識も数少ない。このスポートはヨー・チュー・カンとカーティブ駅間。ほぼ直線、または上坂区です。'+16'は、16‰の意味ですか?各駅の付近はその標識もある、でも'-3'、'-2'、'-1'と'+1'、'+2'、'+3'がいます。Singapore MRT's North-East Line is largely located above ground. As it is fully automated, there are no signals (other than at turn-outs), there are also few signages. This spot is between Yio Chu Kang and Khatib, along a straight section. Wonder if this '+16' means a 16‰ grade?There are such signs before and after stations, but they display '-3'、'-2'、'-1'と'+1'、'+2'、'+3' instead.
