Train journey times from Lincoln to Newark and Nottingham could be dramatically slashed under multi-million pound plans.
The radical proposals could cut travel times between Lincoln and Nottingham by 17 minutes – chopping a journey down from 52 to 35 minutes.
Trips between Lincoln and Newark could also be shortened to around 17 minutes – from around 25 at present.
And train speeds could surge to 90mph – far faster than at present – with level crossing barriers on the route kept down for shorter periods.
A £51 million cash pot has been provisionally allocated to allow the scheme to go ahead in 2014.
Under the plans, officials say the number of trains per hour between Lincoln and Nottingham could also increase from one to two.
The move would be the biggest improvement in rail services in the region for many years.
Cllr Roger Blaney, deputy leader of Newark and Sherwood District Council, said it could trigger a massive boost to the economy both in Lincoln and in the region.
"From a Lincoln perspective, it should be hugely welcomed," he said.
Statistics compiled by council officials show that while the 34-mile journey between Lincoln and Nottingham now takes around 52 minutes, other similar trips are far quicker.
For example, a journey from Crewe to Shrewsbury is of similar length – but takes 22 minutes less.
The fastest average speed between Nottingham and Lincoln is just 43mph – almost 30mph slower than a similar route between Stirling and Perth.
Officials behind the new scheme hope to improve journey times by ironing out inefficiencies in the way the system currently works.
The amount of time level crossings along the route are down for could be one of the things that are cut.
A detailed study to endorse the plans will be completed by January next year.
