Due to single line its avg is low in sbc sspn section but i dont think except near mkl this is the only section in sbc div with very less curves. AFAIK sbc dmm section have very less curves compared to sbc jtj, sbc mys, sbc tk. Im telling this because in Sbc div only in this section 100 kmph psr is visible so literally it means this section is easily fit for 110 kmph. But as you told this train gets very least priority in Swr.
