Jagudan-Mahesana is not really doubled line yet for the main line (Ahmedabad-Palanpur). There is a separate line for Jagudan-Mahesana toward Varetha which has been commissioned. This line separates IR after Jagudan and before WDFC crosses over IR up to just after Mahesana East side platform to avoid crossing two tracks of WDFC for Varetha line. Hope this helps.
