3: Another curve before Remount Road
Pic 4: Large SB of Remount Road
Pic 5: The train taking a last curve and going below the Metiabruz Flyover to enter Majerhat Station
Pics 6,7: The DN Goods Line has been removed at a stretch to accomodate a new crossover from that line to UP EMU Line so that EMU Trains from New Alipur towards Sealdah can use that track
Pic 8: A new crossover being built from DN Goods Line to UP Goods Line to regulate DN Goods trains to UP Line in case of oncoming traffic from New Alipur (just a guess)
Pic 9: The new platform at Tollygunge, numbered as 2, ready and awaiting inauguration
