Analysis of the government’s planned transport spending shows London is set to receive almost 7 times more per person than in Yorkshire and the Humber.
The study from the think tank IPPR North urges the government to turn years of Northern Powerhouse rhetoric into reality.
Sheffield City Region Mayor, Dan Jarvis, said: "What we need to see is deeds, not words."
"I will be pressing the new government to invest a greater amount of money into our transport system, so we can improve the experience for our travelling public".
The Department for Transport says the figures are misleading and it's committed to reversing decades of under investment.
