The required time of the limited express train also increased by five to six minutes from 38 minutes when it ran nonstop from Juso to Omiya: now the outbound train requires 44 minutes and the inbound train requires 43 minutes on average, which is such a considerable slowdown that there is only a two- or three-minute difference from the time it took the express train on February 23, 2001 or before.
また、特急の所要時間も十三～大宮間ノンストップ時代の38分から5～6分延びて、下り44分、上り43分が標準的な所要時間となっており、これは2001年3月23日以前の急行の所要時間と2～3分程度しか変わらない程スピードダウンしている。
