Well m to a fan of ER king...but the contrary my fab is LKO shatbdi...the agreesive TT is has...the way it covers all the delay post ALJN upto GZB is incredible...I personally measured it on 135 KMPH close to Khurja once..
Also LKO Shatbdi (12003 one) Overtake most number of trains between the trains whose journey is close to 500 KM..
Also it was the undisputed KIng of IR (Fatstest for years) until BPL shatbdi arrived and the others as well..
So...
more... that's my personal Fab...
