First, the accent, Xinyang dialect is classified as the Central Plains official dialect Xinyang, Bengbu piece. Henan dialect belongs to the northern dialect which is the official dialect, so it is different in itself. Xinyang dialect is close to Hubei, not only Xinyang, but all the dialects of the places where the two provinces' regions meet will be not quite the same as that of the province.
Second, diet, north of the Huaihe River is noodle-based, south of the Huaihe River is rice-based. So Xinyang has a lot of rice and noodles, but mainly rice.
Third, the railroad, Xinyang station is really Hubei tube, for many reasons, Xinyang is close to Wuhan is one of the reasons, there is now Wuhan Railway Bureau's jurisdiction is getting bigger and bigger, it is not our control. The railroad minister is Hubei.
I am a Xinyang people, I think Xinyang and many places in Henan is not the same, as long as the geographical location of the reason.
I hope my answer is helpful to you,
