JAM ST ICE is now JAM BRC BL ICE. PM at BL
Earlier 12476 used to go to Jamnagar for maintenance that's why 12475 and 12477 days of run got changed
no, it was 12477/12478 which used to travel to HAPA for maint. On Tuesdays, when 12478 dep for JAT was scheduled Ex Jamnagar, then Jamnagar Surat IC used to originate from Hapa on Tuesdays,,,as Jamnagar has only three lines or PFs, and only single line between Jamnagar and Hapa is there,,Both 12478 and JAM-ST IC had very tight schedule, so one train then used to depart from Hapa i. JAM-ST IC just 10 minutes or so before JAM-JAT SF at around 0500 hrs or so,
earlier 12476 used to terminate at Rajkot and was subsequently extended to Hapa so as not to affect schedule of JAM-ST IC
The third pf has been commissioned post-COVID-19. You're right. The same reason why 12267 can't be extended to JAM.
