Disruptions & planned work

A broken down train between Alexandra Palace and Stevenage via Hertford North means that all lines are blocked. As a result, trains running between these stations may be cancelled, delayed by up to 30 minutes or revised. Disruption is expected until 17:30. Customer advice: If you are travelling between Alexandra Palace and Hertford North, please use an alternative route to complete your journey where possible. A train has developed a fault in the Gordon Hill area, blocking the Hertford Loop Line between Gordon Hill and Stevenage in both directions. As a result, trains cannot run through this section and journeys are likely to take longer than normal. Please allow at least 30 minutes extra to reach your destination and check station screens and journey planners before travelling. Changes for services: Services cannot run between Gordon Hill and Stevenage in either direction until further notice. Services that normally run between Moorgate and Stevenage will operate between Moorgate and Gordon Hill only. Peak services that run between Moorgate and Hertford North / Gordon Hill have been suspended. Services between Moorgate / London Kings Cross and Stevenage will now run between Finsbury Park and Stevenage using the East Coast Main Line, instead of the Hertford Loop. Services routed via the Main Line will depart Stevenage earlier than normal and may incur additional waiting time at Welwyn North to regulate service. Ticket Acceptance: Your ticket may be used at no extra cost on the following: Alternative Great Northern and Thameslink services between Moorgate, London Kings Cross and Stevenage Greater Anglia services between London Liverpool Street and Hertford East. This will be a bus between Broxbourne and Hertford East. Then from London Liverpool Street to Broxbourne this will be a train London Overground between Liverpool Street and Enfield Town London Underground between Moorgate, King's Cross & St Pancras International and Cockfosters Replacement buses: Buses have been requested from suppliers, but there hasn't been confirmation of these yet. If we can provide a bus service, we'll let you know by updating this message. Bus journeys will take longer than your usual train journey on this route, and if possible, a time estimate will be provided here. Planning your journey: For help planning your journey, check live departure boards , view a live network map or see alternative route guides . If you’re travelling within London, you can use the TfL Journey Planner . Stay up to date on the move with Great Northern's WhatsApp channel . Live updates are available Monday to Friday, 07:00–21:00. Can you tell me more about the incident? Unfortunately, a train in the Gordon Hill area has developed a fault. The nature of the issue means it can't move, so it's blocking the line through the Hertford Loop in both directions. It's likely that in this case, we'll need to send our specialist engineers to site, known as "fitters". Fitters are based in key locations around the network, 24 hours a day, and they are able to attend anywhere on routes. Once they are on site, progress updates will be monitored to ensure that the railway can be reopened as promptly as possible. Another train may also need to be sent to tow the defective one away. This procedure, known as arranging a rescue train, will be done as quickly as possible, usually by sending a similar type of train to attach. The combined train will be taken out of use and sent to a depot. Until the defective train can be moved, an alternative way to get other trains around the issue will be explored. This depends how many lines are available, and whether the signalling equipment is set up to allow trains to be routed around the problem. This is more often the case on major routes, but not always. Work will be undertaken with Network Rail's controllers to decide how many more trains can be sent through the area, and if this isn't possible, alternative solutions will be explored to help you continue your journey. Ticket flexibility: If your train is cancelled, you will be able to travel on an alternative service operated by any other participating train company , either two hours before or two hours after the original departure time of the cancelled service, in order to reach your destination. If you decide not to travel or cannot complete your journey due to cancellations, you are entitled to a full refund from your original point of sale. For further information and guidance please contact your train company or speak to a member of railway staff. Check before you travel: You can check your journey using the National Rail real-time Journey Planner . For helpful advice if you need to travel on a rail replacement service, including accessibility and bicycle information, please use our Rail Replacement Services page . You can find the pick-up and drop-off location of rail replacement services by checking station signage or by searching for your station on our Find a Station page . Please be advised that replacement vehicles may be busier than usual, and you should allow extra time for your journey. Compensation: You may be entitled to compensation if you experience a delay in completing your journey today. Please keep your train ticket and make a note of your journey, as both will be required to support any claim.
