The north of England "needs transport investment now", the Mayor of Greater Manchester said as northern leaders gather at a transport summit in Leeds.
The meeting of political and business officials at Cloth Hall Court was a "packed house", he said.
Mr Burnham said:"This isn't about point scoring, it's about making the argument for the north".
"The success of northern transport depends on the north itself," the transport secretary had said.
'Not a big challenge'
On Tuesday, former Chancellor George Osborne called for high-speed rail lines between Liverpool and Hull.Following his comments, Northern Powerhouse Minister Jake Berry said during a visit to Hull that HS3 "will happen" .
Among the delegates attending the event are leaders of Leeds, Newcastle and Manchester councils, Liverpool City Region Metro Mayor Steve Rotheram and business representatives.
Speaking at the conference, former economist Lord Jim O'Neill said:"It shouldn't be that big a challenge to put in infrastructure to make urban-based areas [in the north] as big as London."
He said transport was one of six key areas for the north - the others being education, skills, devolution, business and ambition - to focus on and called for the government to commit to funding in local infrastructure.

Organisers have described the summit as an "unprecedented gathering" of leaders from councils and businesses who want more investment in local infrastructure.
It follows an announcement from the government last month that it was scrapping the planned electrification of railway lines in Wales, the Midlands and the north of England, which angered authorities and businesses.

Labour leader Jeremy Corbyn has begun a tour of Scottish constituencies with a visit to the Western Isles.
Mr Corbyn will meet staff at Harris Tweed Hebrides before addressing a town hall rally in Stornoway, highlighting his party's policies for rural areas.
He will then tour a series of marginal seats in Scotland over the next five days, attending speeches and rallies.
The Tories say his policies lack credibility, while the SNP were critical of his position on Brexit.
However, they were less than 100 votes behind the SNP in two Glasgow seats, and less than 1,000 votes behind in six Scottish seats in total.
With the election result stripping Theresa May's Conservatives of their majority in government, Mr Corbyn has pledged to remain on an election footing.His party has identified up to 18 Scottish seats as potential targets.
The Labour leader is using his visit to the Western Isles to highlight Labour plans to "rural-proof" policies in government, so that all laws are assessed on their impact on rural communities.Image caption
Mr Corbyn said:"Rural communities have been taken for granted for too long.There has been chronic underinvestment in transport, broadband and public services, with rural infrastructure and industry neglected.
"Labour will invest in transport, broadband, public services, housing and environmental and coastal protections - vital for the economy and the rural way of life."
A spokesman for the party said Mr Corbyn's "backing for the Tories' extreme Brexit, outside the single market and customs union, is set to hit our rural communities hardest".
He added:"Rural areas benefit massively from our membership of the EU, having access to funding, tariff-free trade and a highly-skilled labour market.
"Sadly, rather than wanting to protect these benefits for rural communities, Labour are pledging to deliver an extreme Brexit.Jeremy Corbyn and Labour simply cannot be trusted to deliver for rural Scotland."
The Scottish Conservatives, meanwhile, said it wasn't long ago that Scottish Labour "dreaded the thought of Jeremy Corbyn coming north".
MSP Miles Briggs added:"Had he won the general election, Corbyn would have sold Scotland out in a heartbeat, and that ambivalence to Scotland's place in the UK hasn't changed."...
