Sir As per IRI Atlas this is not the last MG in NFR.
What about MG Line :
Ledo - Lekhapani (Shown in atlas as MG)
Amguri - Tuli (Shown in atlass as Gauge conversion)
Dekargaon...
more... - Tezpur (Shown in atlas as MG)
And a parallel MG line between DITOKCHERRA - MAHUR (I guess this MG line is abondoned due to construction of BG line in parallel with this MG line)//??
