These should be the order for priorities in budget , what you say guys:
P1 - Guage Conversions
P2 - Basic Facilities at Stations - like well maintained Toilets, Quality Food Stalls, Waiting Rooms
P3 - New Lines - (Already approved ones)
P4...
more... - Doubling lines
P5 - Other Facilities at Stations - like Escalators on major stations
P6 - New Trains (demand may reduce if P1, P3 are done since routes for some trains can be altered)
P7 - Triplification (if P1,P3,P4 are done there would be enough alternate routes, eliminating immediate need for triplification)
