I agree.. kindly keep us updated regarding track doubling/electrification status on IRI if possible with pictures n videos too. I am slightly tired of seeing semaphore signals near Pratapgarh and Rae Bareli stations, although they have their own old-world colonial charm. Even the PBH route deserves to serve trains between BSB and LKO at high MPS.. I guess if the SLN route is aimed for bringing down travel time from around 7 to 4 hours then the PBH-RBL line can also try for a 5 hours superfast journey between BSB & LKO.. what say?? :)
