In a rail yard near Milton Keynes, a team of workers clad in orange are conducting final inspections on massive sections of railway track, preparing them for installation during the Christmas and New Year period.

While many commuters take a break from work to enjoy the holiday season, railway officials utilize this time to undertake large-scale engineering projects and upgrades.

As a result, the orange-clad workers are out in full force, ensuring that essential maintenance is carried out.

Carl Foy, a veteran rail worker, has spent approximately 20 out of 27 Christmases on duty, with this year being no exception. He will be joined by his two grown sons, who are also rail workers, and while some friends may think he's crazy for working during the holidays, Carl views it as an inherent part of his job.

To make the experience more enjoyable, Carl and his colleagues bring in mince pies, and the site offices are decorated with tinsel. Despite the challenges, they focus on completing their tasks.

The £26m project they will be working on this Christmas is one of the largest scheduled nationwide, involving the Hanslope Junction, a critical section of the West Coast Main Line that is showing signs of wear.

With nearly 500 trains using the junction daily, the increasing number of faults is causing delays that have a ripple effect throughout the network. To address this, the entire junction, comprising four tracks, will be re-laid.

The project involves a complex jigsaw puzzle of 130 separate track panels, which cannot be completed while trains are in operation. Consequently, passengers will face disruptions, including no direct trains between Milton Keynes and Rugby or Milton Keynes and Northampton, from late Christmas Eve to January 5.

Similar projects are underway across the country, including the upgrade of signalling technology, with 5% of the rail network scheduled to be closed during the festive period as part of a £160m engineering project organized by Network Rail.

Many of these projects are substantial undertakings that have been meticulously planned, with allocated funding as part of Network Rail's five-year business plans.

The question remains as to why these projects are scheduled during the holiday season, causing significant inconvenience to many travelers, and whether this is a result of prudent planning or an indication of underlying issues with Britain's rail network.

Conversations with passengers at London Euston station reveal that many are affected by the disruptions, with one woman mentioning that her sister-in-law is having trouble finding a suitable train, resulting in multiple changes and a longer journey time.

Another passenger, traveling to the North of England, is considering driving instead of taking the train due to the potential disruptions and inconvenience.

The passenger acknowledges that there are fewer commuters during the Christmas period, making it a strategic time for maintenance, but notes that it can still cause problems for those trying to visit friends and family.

The debate surrounding the scheduling of engineering works during Christmas is complex, with train bosses arguing that the impact on commuters will be minimal due to the holiday season.

According to Jake Kelly, a regional managing director at Network Rail, the Christmas period is the quietest time of year for the railway, making it an ideal time to undertake maintenance and minimize disruptions.

However, rail engineer and campaigner Gareth Dennis argues that this approach can create a "bottleneck" and is also extremely expensive, with workers receiving higher pay for their work during the holiday season.

Mr. Kelly acknowledges that there is a cost associated with undertaking work during Christmas, but emphasizes that it is a difficult trade-off between minimizing disruptions and containing costs.

In comparison to other European countries, Britain's approach to rail maintenance during Easter and Christmas is unique, with the exception of Italy.

According to Mr. Dennis, this is partly due to the layout of Britain's rail network, which is more north-south oriented, making it more challenging to undertake maintenance without causing disruptions.

The high demand for rail services in Britain also poses a challenge, with the West Coast Main Line operating at full capacity and the East Coast Main Line's new timetable set to increase traffic.

Another factor contributing to the strain on the network is the legacy of underinvestment, which has resulted in a significant backlog of maintenance work.

Stewart Palmer, a veteran rail industry expert, notes that the lack of funding in the past has led to a "mend and make do" approach, resulting in a significant amount of work that needs to be done now.

The legacy of underinvestment has a long history, with engineering works often being postponed, and speed restrictions imposed on certain sections of track to ensure safe operation.

The 2000 Hatfield rail crash, which resulted in four fatalities, highlights the importance of replacing deteriorated rail in a timely manner, with an official investigation revealing a series of errors, including the failure to identify and repair or replace worn-out rail.

The crash led to a significant increase in engineering investigations and the replacement of a large amount of rail in a short period.

Climate change also poses a significant challenge to the rail network, with extreme weather events causing equipment failures and affecting the wear and tear of infrastructure.

According to William Powrie, a professor of Geotechnical Engineering, climate change creates a range of hazards for the railways, including heat-related track buckling and damage to overhead lines.

He is particularly concerned about the "paperclip" effect, which can cause significant damage to rail infrastructure.

Network Rail has acknowledged the impact of climate change on the rail network, stating that it will affect the safe and reliable operation of the railway.

The combination of these factors has resulted in a complex situation, with the need for significant maintenance and upgrades to the rail network, while also minimizing disruptions to passengers.

The challenge for rail officials is to balance the need for maintenance with the need to minimize disruptions, while also addressing the underlying issues that have contributed to the current state of the network.

As the rail network continues to face these challenges, it is clear that a long-term solution will require a combination of strategic planning, investment, and innovative approaches to maintenance and upgrades.

The legacy of underinvestment and the impact of climate change will need to be addressed, and the rail industry will need to work together to find solutions that balance the needs of passengers, workers, and the network as a whole.

The situation highlights the importance of prioritizing rail maintenance and upgrades, while also acknowledging the complexities and challenges involved in ensuring the safe and reliable operation of the network.

By understanding the factors that contribute to the strain on the network, rail officials can work towards finding solutions that minimize disruptions and address the underlying issues.

The impact of climate change on the rail network will require a proactive approach, with a focus on adapting to the changing weather patterns and mitigating the effects on infrastructure.

The "paperclip" effect, heat-related track buckling, and damage to overhead lines are just a few examples of the hazards posed by climate change, and the rail industry will need to develop strategies to address these challenges.

The expertise of professionals like William Powrie will be crucial in developing solutions to these complex problems, and in ensuring the long-term sustainability of the rail network.

As the rail industry continues to evolve, it is clear that a collaborative approach will be necessary to address the challenges posed by climate change, underinvestment, and the need for maintenance and upgrades.

Britain's railway infrastructure is largely built on clay soil, which is prone to shrinkage during summer months due to water absorption by vegetation, and expansion during winter. This cycle of contraction and expansion is becoming increasingly pronounced, according to experts.

The repeated stress caused by this cycle can be likened to the bending of a metal object, such as a paperclip, which will eventually break if bent back and forth repeatedly, illustrating the potential for damage to railway tracks.

Railway maintenance extends beyond the tracks themselves, as embankments and drainage systems along the lines also require attention. A recent example of the importance of this maintenance is the derailment of a train travelling from Glasgow to London on the West Coast Main Line near Carlisle in November, which resulted in four injuries after the train hit a landslip.

An investigation into the cause of the derailment is underway, with preliminary findings indicating that a drainage channel was overwhelmed by the volume of water present, highlighting the need for effective drainage systems.

Network Rail has acknowledged the risks associated with climate change and is reallocating funds to address these issues, with £2.8bn earmarked in its latest five-year business plan to mitigate the effects of extreme weather and climate change.

Despite these efforts, the organization is facing significant financial pressures, with a target of £3.9bn in cost savings, which will require difficult decisions regarding resource allocation.

According to Andrew Haines, Network Rail's former chief executive, the organization is experiencing the impacts of inflation and rising supply chain costs, similar to many other businesses, as outlined in a recent update.

As a result, the company will need to make "tough choices," including prioritizing maintenance and repairs on busier sections of the network, as stated by Haines.

However, the Office of Rail and Road has warned that the constrained funding may lead to a decrease in renewal work and an increase in temporary repairs, potentially resulting in more frequent asset failures and disruptions to train services in the long term, as well as higher costs in the future.

For the millions of passengers travelling during the Christmas season, the primary concern is often simply reaching their destination, and they are advised to plan ahead and check for updates before embarking on their journeys.

Looking ahead to next year's Christmas season, it remains to be seen whether railway passengers can expect a more reliable travel experience.

Jake Kelly of Network Rail suggests that this may not be the case, citing the example of the Hanslope Junction project near Milton Keynes, which can take years to plan and implement.

With a planning pipeline that spans three to four years, Kelly notes that plans for next year are already being finalized, highlighting the long-term nature of railway infrastructure projects.
