He called a meeting of top officials both from Railways as well as Road and Highways ministries to sort out differences between them over construction of road over and under bridges at level crossings.
The difference between the two ministries came in the way of expansion of highways.
"Railways and NHAI should work together in finalising the designs of these bridges. They should evolve a system to standardise the designs," Joshi, who is also Minister for Road and Highways, said.
The minister, who was given additional charge of Railways after TMC withdrew support to the UPA government, said he will set the agenda for his ministry after holding discussions with Railways officials.
Talking to reporters after his maiden visit to Rail Bhawan here, Joshi said, "Safety will be my top priority, along with passenger amenities and modernisation of rail infrastructure.
"The aim is that railways have an active role in India's economic growth."
