"At present, due to over-utilised line capacity and backlog in track renewals, there are speed restrictions which lead to delay in running more number of trains.
"The review will be completed soon so that we can announce new trains and increase frequency in this session," Prabhu said in his maiden rail budget speech.
Government's proposal of not announcing new service, arguably the first time in decades, comes despite heightened demands from states as well as Members of Parliament for announcing new trains in the Budget.
"Trains which are fully patronised throughout the year, will be augmented with additional coaches from trains which have relatively lower occupancy levels.
"Further, capacity of identified trains will be augmented to run with 26 coaches from existing 24 coaches. More general class coaches will be added in identified trains to benefit the common man," the Minister said.
