SIR then what is the use of constructing that flyover near Siliguri Town....??? Both Indian Railways & SJDA have invested crores in building,still that level crossing gate has not been removed...I think rly should permanently seal the gate...as we go little ahead towards SGUJ can see boundary walls,same walls or fence should be created along the tracks....already SGUj APDJ section has been affected by elephant corridor,now we cannot compromise speed in SGUJ NJP section...totally agree that NG section can be converted into dual gauge..another parrallel bridge on Mahananda can also be considered...whatever gates remaining,can be upgraded to RoB or RuB....this is no uphill task...only proper planning is required on part of W.B. Govt & Katihar Division,NFR.....
