If extant buildings were to be fully preserved on their original sites, the MRT tracks would have to be rerouted, delaying completion by 62 months and increasing the cost by NT $ 4.5 billion; or the train yard would have to be relocated.
如果現有建物全部原址保存，將出現軌道路線變更等問題，預估工期最長增加 62 個月，經費增加 45 億元，甚至可能導致機廠遷移、另選廠址。
