Enfield MPs Nick de Bois and David Burrowes led a debate in parliament about the train service which runs through the borough.
Both Mr de Bois, MP for Enfield North and Mr Burrowes, MP for Enfield Southgate, have voiced commuters' concerns about frequent disruption to the First Capital Connect service that passes through Enfield on its way into London.
The company has said it will be looking into the situation to improve conditions on the line.
However, both MPs have now debate in Parliament about the issues, along with other MPs with constituencies along the route.
Mr de Bois said: “MPs representing constituents along the whole of the Hertford Loop joined me for this debate to press First Capital Connect and Network Rail to urgently deal with the appalling delays and cancellations passengers have faced in the past few months.
“Clearly long-term work that will bring improvements is under way, but there are steps that can be taken now to help ease the delays. FCC has been left in no doubt about what to do and we have full ministerial support for them to act swiftly.”
Mr Burrows said: “For too long my constituents have had to put up with sub-standard services and this must stop. As a London commuter I appreciate the frustrations and problems that unexplained cancellations, service alterations and delays can cause to those who work and travel daily into London.
“First Capital Connect can no longer ignore this issue, as this debate has helped put my constituents’ concerns on record here in Parliament.”
