A railway line that used to connect vast areas of Liverpool to the city centre is at the heart of a call to improve transport across the city.
The North Liverpool Extension Line closed in 1972 - and despite plans to use it to provide another loop line for the Merseyrail network it has stood empty since then.
It previously connected many areas of Liverpool which now have no direct access to the rail network, including West Derby, Gateacre and Knotty Ash.
And now a councillor from one of the areas it used to serve has called on city leaders to consider reopening the line as an option to increase his area's transport links.
Knotty Ash Councillor Harry Doyle said his ward and others around it suffered with less public transport than other areas of the city - and that the line was one way of helping that.
Councillor Doyle said: "Across the south and north of the city, residents have multiple modes of transport including a rail link into and out of the city.
"This is something that residents in East Liverpool do not have.
"Both West Derby and Knotty Ash were previously served by the Liverpool Loop Line, and I believe this has the potential to be brought back into use."
He said he realised financial constraints would mean any plan to resurrect the line would likely be far in the future - but that the city should be ambitious in its long term plans.
Originally opened in 1879, the line branched off the Liverpool to Manchester line near Hunts Cross and looped back up around the city before finishing near the docks and connecting to the Southport line.
It was closed in stages throughout the middle of the 20th century.
A plan to create a Merseyrail 'Outer Loop' using much of the track was floated in the 1970s but ran into a number of financial problems and was eventually abandoned.
Most of the route remains in place, with part of it making up the Liverpool Loop Country Park walking and cycling trail.
Councillor Doyle said that a serious look at bringing the line back into use, as well as improving the bus network and conditions for pedestrians in the east of the city, would help Liverpool reduce pollution and combat climate change.
He said: "Whilst I recognise we may not have the funds to do this now, I do believe that this should be part of what would be our long term transportation plan for the city.
"If we are not ambitious and bold with our ideas now, we will never achieve an expanded public transportation network for East Liverpool and this will not help our ambition to become a climate friendly city."
Current Merseytravel and Liverpool City Region Combined Authority transport plans do not include the line as a potential development for the future.
