Bhai nothing will speed up.
#RVNL never completed their projects on time irrespective of given to any contractor i.e. L&T or anyone else so no more expectation. Let them take their sweet time for GC then wait for CRS and wait for rakes to assign and wait of passengers trains, express trains and doubling then electrification. Like this list is very long. NER is becoming very slow in their own routes. God help NER.
