Every day, millions of people depend on the British railway system, using train companies as renowned as Virgin, Northern, ScotRail and Eurostar. Helping people travel to work and school and to visit their friends and family, others, such as businesses, rely on the railway industry for rail freight transports of stock and everyday essentials, like fuel and food. As Network Rail states in ‘Delivery Plan. Control Period 6. High Level Summary’: ‘’Rail also helps our towns and cities thrive, making them great places to live and do business. The railway is at the very heart of Britain’s economy.’’

In February 2018, after reviewing service levels, Network Rail announced its strategic business plan for Control Period 6 (CP6), prioritising performance and reliability improvements over major new schemes. Covering the period from 1st April 2019 to 31st March 2024, the £53 billion budget will see £18.5bn invested in operations and maintenance, £10bn invested in current scheme enhancements to allow capacity improvements and £1bn has been allocated to support the planning and development of future enhancement projects which would be authorised and funded on a case by case basis once they are sufficiently mature – for example. The ultimate goal is to provide passengers with a reliable railway, without dependency on central government support.

These are ambitious plans, and to deliver such services requires dependable power systems, such as PADS Approved UPS systems, also known as Severe Environment UPS or Rugged UPS. In fact, PADS Approved UPS systems are the only UPS power supply allowed to be used on rail infrastructure, ensuring compatibility of the unit and most importantly that safety requirements are in place. CP6 makes it a priority to use PADS Approved UPS systems, and here at Dale Power Solutions, that’s exactly what we have provided.

What Is Control Period 6 (CP6)?

Control Period 6 (CP6) is a service delivery plan created by Network Rail, detailing how they’ll be spending the £53bn worth of investment from the Department for Transport (DfT) and Transport Scotland. Impacting 14 key routes, including the East Coast Route, Anglia Route, North West Route, Scotland Route, Sussex Route and Wales & Borders Route, Control Period 6 (CP6) is underpinned by six business themes:

Safety

Control Period 6 (CP6) aims to make the railway a safer place for everyone by reducing risk to passengers, the public and through protecting the workforce. For example, by 2024, Network Rail plans to reduce train accident risk by 10%, and risks at level crossings by 13%.

Train Service Delivery

Improving train performance is at the heart of CP6, and this involves reducing service-affecting failures, and reducing incident delays. Network Rail plans to reduce Network Rail related delays by 7% as compared to 2017/18, and by 2024, to reduce service-affecting failures by 7% too.

Efficiency

Network Rail has, ‘’an ambitious but achievable target of saving £3.5bn across CP6 in running the railway by making more efficient use of railway resources and working smarter.’’ This comprises using state-of-the-art hardware and software, alongside modernised innovative processes, involving the supply chain in the design, planning and delivery stages, and improving commerciality of the railway.

Sustainable Growth

Sustainable growth in CP6 involves increasing capacity to deliver the priorities laid out in the Hendy Review, as well as seeking out strong business cases that promise improved punctuality, journey times and reliability for passengers or support critical policy goals like economic growth and carbon reduction.

Key environmental goals under ‘Sustainable Growth’ include:

  • A reduction in carbon emissions by 25%.
  • A no-net biodiversity loss by 2024 and biodiversity net gain by 2040.
  • Zero waste to landfill by 2024.

People

As stated in CP6, a ‘’diverse workforce is also crucial to the long-term success of Britain’s railway and we want to lead the industry in helping achieve that. That means creating an environment where everyone is proud to work here, proud of what they do and have the opportunity to reach their personal potential.’’

Customers and Communities

Control Period 6 emphasises a better standard of customer service and the creation of a stakeholder charter, which will reside on Network Rail’s website and will publicly set out their commitment to our passengers, customers and stakeholders.

Control Period 6 works on the foundation of rail companies across the UK working together and implementing effective solutions for their customers.

FAQs

What are then main parts of a critical power system?

Generator: Provides stand by power until the mains power can be reinstalled

UPS (Uninterruptible Power Supply): Ensures a seamless transition from mains power to the standby power (generator)

Batteries: Provide the power to your UPS and Generator.

How often should I service my system?

All parts of your critical power system should be regularly maintained, serviced and thoroughly tested and depending on the criticality of the system we recommend 2 services per year as a minimum, always carried out by qualified engineer.

 

When we install a critical power system, we will recommend a maintenance programme specific to your particular installation. It is important to note that regular maintenance completed at the right time and equipment updates will ensure your system is working at optimal efficiency and in turn offer long term cost savings to the organisation.

More information on checks for Intermittent Use and Light Load Operation.

Why do I need Load Bank Testing?

A controlled, load bank test, checks that all aspects of the system are working correctly, including the entire electrical supply infrastructure (cabling, switchgear, generator, fuses) ensuring your system is capable of taking on a full load during a power outage. Back-up power will only work if it can support the required critical power load and therefore, we would always recommend regular load bank testing if the generator is not being used on the building load.

How often should I change my batteries?

Starter Batteries: Owing to the harsh starting conditions (high discharge for the initial start and then high charge currents from the charge alternators for a rapid recharge) and bearing in mind that they are positioned near an engine, means that starter batteries do not have the lifespan they would have if they were connected to a UPS. Battery manufacturers therefore do not provide a recommendation for changing. We can, and do advise, depending on the battery type, environment and application.

Note: A reminder to change batteries can be set in most cases to the UPS operating software.

Can you still service and repair my equipment if it’s not from Dale?

Yes, we support most OEM critical power equipment. You receive the same excellent 24/7, nationwide service for all your equipment, and one maintenance partner makes life a lot simpler.

What is the best configuration for my generators?

This depends on the load being supported and whether the unit connects across site supporting multiple loads.  For dedicated loads and locations single units are often utilised, however we would recommend for single units there is a connection for routine load bank testing and a temporary hire unit should one be required.  For centralised standby generators these are normally configured in an N+ configuration, to ensure the most critical loads can be supported in the event of servicing or failure of one of the generator units.

What’s the difference between remedial and preventative work?

Preventative scheduled maintenance is always preferable as this will pick up on any remedial work needed which can then be carried out at a suitable time. Don’t wait for an emergency to test your system is working.

How do I ensure my critical power equipment is working to optimum efficiency?

It is important to note that regular maintenance completed at the right time and equipment updates will ensure your system is working at optimal efficiency and in turn offer long term cost savings to the organisation. When we install a critical power system, we will recommend a maintenance programme specific to your particular installation.

We would recommend discharge testing every 6 months to ensure you have sufficient power when you need it.

How can I achieve any cost savings with my critical power system?

Regular, planned maintenance keeps costs and inconvenience to a minimum because work is carried out at a suitable time, rather than having to be done at short notice under emergency conditions (when the generator is actually required).  Increased reliability will mean that the set will be available when required.

 

Regular maintenance has other benefits:

  • Major repair bills should be avoided as potential trouble can be corrected before it has a chance to develop into major faults and therefore running costs will be reduced
  • Since the equipment will always be running under optimum conditions, operating life will be extended
  • Planned maintenance also reduces down time (minimum impact on productivity). Maintenance work can be scheduled when it will cause the least disruption to the organisation’s activities
  • Condition based monitoring of fuel, coolant and oil will keep a check on quality and is more cost effective than replacing it. Engineers should sample fuel coolant and oil yearly.
