Rail Case Study

What is the problem to be solved?

Those identifying as part of the rail industry frequently receive unsolicited train journey horror stories. It is rare that such well-intentioned and honest feedback doesn’t include comment on how poor their on-train voice and data (Internet) experience has been. As mobile device users,we have come to expect consistently good connectivity, both at-home and on our travels. The on-train experience now stands-out as Britain’s last great connectivity wilderness.

Despite on-train WiFi provision being relatively ubiquitous in the UK, poor passenger experience results from a failure to deliver an appropriate wireless, satellite or mobile connection between the train and terrestrial telecoms networks. A lack of structures investment to improve connectivity to trains can be attributed to ministers, policymakers, rail operators and connectivity providers having no evidence as to economic and societal benefits of connecting passengers.

Rural communities are benefiting from government initiatives to improve home broadband and mobile connectivity, resulting from voter pressure on local representatives. No such functional collective exists for train passengers to influence government policy. Further, where passengers have been canvassed (for example, by Transport Focus), more fundamental needs around the journey itself have overshadowed not being able to use travel time effectively.

The UK railway is not a single entity, but an amalgam of government, arms-length government, government concessionaires and commercial entities. When considering train passenger connectivity, this collective must also be extended to include the government regulated telecoms operators. The railway trackside, and passenger trains, are also a very expensive environment in which to deploy and continuously upgrade technologies. The EvoRail experience of deploying trackside Gigabit train connectivity from Basingstoke and Earlsfield on the South West Main Line has demonstrated unsustainable challenge and cost.

Problem

This lack of common benefit vision, or a compelling reason for change, is the underlying cause of a historical policy, market and industry failure to deliver a satisfactory connectivity service for train passengers. Government and industry lack universally understood and evidenced insights as to the economic and societal value of train passengers being able to continue their connected lifestyle whilst taking the train. The missing evidence not-only covers the direct benefits of being connected, but also the opportunity cost of failing to drive-up ridership by offering enhanced time value.


What is the solution to the problem?

Directly serving users with an on-train network represents an efficient, reliable, scalable and future-proof means to resolving the current challenges to passenger connectivity. To date, this approach has been largely delivered as a WiFi service across much of Britain’s passenger train fleet. This approach does not preclude retrospective on-train deployment of small cells delivering native mobile connections for the mobile operators. But before envisaging any business or technology solution, it is proposed to undertake a three-phase programme or research:

  1. To understand the societal and economic value of that usage as part of a train passenger journey. Section 5 identifies potential areas of benefit that need to be explored in a formal and reasoned expert study. This will need to include a literature search for other rail deployments, interviews of digital content and service providers, leading to a robust analysis and reporting.
  2. To understand connectivity requirements eg speed, security, data load, update rate on a per-user and per-train basis. There is currently no available evidence as to what train passengers use connectivity for, and what economical and societal value this creates. Ofcom’s 2018 report (Advice to Government on improving rail passenger access to data services) provides a credible technology-driven pitch but appears to be based upon extrapolation and aggregation of current device usage trends, rather than considering purpose or value.
  3. To scope and undertake validatory testing of the research to assure its fitness for the creation of government policy and business cases. This is likely to require a greater than normal scrutiny of the digital activity of train connectivity users and possibly require specific governance and user opt-in. A currently funded E-W Rail passenger connectivity trial, along with the newly introduced EvoRail South West Main Line WiFi service, are seen to be credible partners for the validation.

Following a successful outcome, and with a route for government and/or industries to evidence benefits, opportunities will emerge to improve passenger connectivity on an area, line of route or national basis. These include:

  • Government policy change, resulting in direct funding for strategic partnerships and capitaldeployment.
  • Changes to Government regulator (ORR, Ofcom) franchise or licence obligations to the rail and/or telecoms industries resulting in action by those parties.
  • Commercial initiatives arising out of a better understanding of how to build a business ecosystem which supports capital expenditure and a sustainable flow of revenues to the deployer.
  • The development of a cohesive industry view as to how a future spend by Network Rail for the migration of GSM-R to FRMCS could become part of a positive business case to deliver both FRMCS and passenger connectivity in a more efficient way.

Commercial model (Business Case)

There is currently little evidence of an attractive commercial model to enhance the ground to train connectivity necessary to deliver a satisfactory on-train train passenger connectivity experience in Britain beyond un-quantified returns to mobile operators achievable from best endeavours coverage of the railway from existing masts. All other track to train connectivity deployment and enhancement initiatives have been pilot deployments (Isle of Wight), local government enabled (Merseyrail) or those satisfying commitments made as part of the passenger franchising process (Avanti and EE on WCML). In many cases, costs and benefits (unknown) have fallen to different parties, making the challenge even greater.

As previously observed, for any commercial solution to the problem, the stakeholder community is a complex set of pseudo-government (Network Rail and some train operators) government franchisees (most train operators) and asset-owning commercial entities (rolling stock companies). There is currently no common vision, policy or action across this community to realise an affordable step-change in passenger connectivity. Without quantified evidence of benefit, it is difficult to see how a robust benefit case can be built by any of the parties previously discussed.

The community of telecoms providers (including Network Rail themselves) is equally complex and fragmented, with no single entity in a leading position to realise an attractive commercial model for a ubiquitous connectivity offering. To date, an opportunistic collection of mobile operators, neutral host providers, trackside and train-top solution suppliers have harvested the low-hanging fruit of connectivity revenue loss (MNO not-spots on high passenger flow routes, including London’s underground railways) and specific one-off funded opportunities.

However, with the recommendation for research identified in the previous section and the potential areas of benefit identified in the following section of this case study, it is believed that the stakeholder community could build a viable commercial model to (in the words of Daniel Susskind’s New Statesman article) “Hurry up and fix the wi-fi”. With an apparent commitment to realise Great British Railways under the emerging Conservative and Labour election manifestos as (respectively) a guiding/directing mind, a incentivised recipient for a commercial foundation could emerge.


Benefits

Improved railway trackside connectivity will only deliver limited benefit to the operation and management of the railway. RSSB’s 2012 report (Operational Communications - a programme of work to develop an effective strategy that supports rail innovation) looked at connectivity needs but failed to find any benefit case for improvement. From a current view, it appears that Britain’s railway is likely to be self-serving with its existing GSM-R network and its migration to 5G FRMCS during the 2030s. Usage will also be made of public 4G/5G mobile and satellite services where these exist, but the findings for the RSSB report indicate that incremental benefits from filling “not-spots” are unlikely to result in a positive business case.

For this reason, section 3 of this case study recommends research into the economic and societal benefits of connecting train passengers, where potential benefit streams need exploration (commissioned research) and validation (the proposed pilot) as follows:

  • The value of productive passenger time over all UK train journeys was assessed by economist Daniel Susskind as being in the order of £18bn a year. In his New Statesman article, he went on to estimate the value of the time lost on trains due to bad or absent wi-fi being £376m a year. This indicates the potential to quantify value to individuals and employers, with consequential gains to GDPR.
  • A richly connected passenger also represents a commercial opportunity for discretionary purchase of digital services, this promoting the commercial development of new digital products and services; again, positively impacting GDPR. The UK digital marketplace has shown strong innovation potential in the creation of applications for infotainment, journey planning, guidance and personal welfare (including for vulnerable travellers).
  • Societal benefits can likely be expressed in financial terms where, for example, the care costs of physical and mental health may be reduced if a continuous user connection supports digital healthcare; possibly AI-powered. Again, the UK digital marketplace is delivering strongly in e-Care and wider adoption is likely if these technologies function correctly during train journeys.
  • Driving passenger numbers upwards will be vital to deliver government sustainability goals and greater ridership, combined with intelligent demand management stands to make the railway more affordable for taxpayers and users. A communicable rich connectivity experience could actively drive-up train usage whereas an experience which is comparatively worsening with time stands to make rail an increasingly unattractive option for travellers. It is also likely that societal, including health, benefits can be attributed to increased rail usage, whilst not creating and adverse sustainability impact.
  • A rail travel experience that represents a natural extension of a person’s life, thus making rail a de-facto part of integrated transport thinking, can further build the case for “Beeching re-opening” initiatives. The enablement of integrated transport is expected to be a strong focus for Great British Railways. The arrival of the Metaverse and the potential emergence of personal digital assistants may fuel a pragmatic inclusion of rail in personal logistics.
  • Finally, and currently of understated significance, a cohesive train connectivity strategy that delivers a national capability ahead of UK rail needing to retire GSM-R could result in £bn savings in the capital cost for migration to the future FRMCS standard. A single combined ground to train data connection can also offer greater data throughputs for future railway operational use-cases than could be delivered with the modest amount of radio spectrum currently being allocated for FRMCS.

Lessons Learnt 

The list of positives is short and mainly limited to an acceptance that this has never been a technology-constrained problem. With the possible exception of needing to encourage the market to develop satellite antennas that are more physically suited to UK trains, there is no requirement to commission trials of novel technology or deployment methodologies. In-fact several credible and mature technology approaches to connecting the train to telecoms networks and the Internet can be evidenced:

  • Radwin “fibre in motion” supporting WiFi on Merseyrail underground train services [track to train connectivity with high hundreds of Mbps throughput]
  • Boldyn Networks multiple MNO service delivery on London Underground [“though the window” native 4G/5G mobile connectivity to passengers with aggregate throughput in the high hundreds of Mbps]
  • Blu Wireless millimetric connection for Isle of Wight and South West Main Line trains [track to train connectivity with multiple Gbps throughput] along with international deployments for Caltrain on their Silicon Valley main line.

Moreover, Innovate UK are currently funding Blu wireless to develop a wireless back haulcapability into their gigabit track to train connectivity solution and Ingram Networks toi nnovate around providing 10 gigabit track to train connectivity. Starting the list of don’ts with a technology observation, it is noted that whilst many train passengers currently make use of through-window native mobile connectivity to access digital services, it is suggested this approach is not credible for well-understood reasons:

  • The penetration of signals into the carriage, even for the most “RF transparent” passenger trains, is sub-optimal resulting in poor user experience.
  • Mobile networks can struggle to deliver good railway coverage due to the number of tunnels and cuttings.
  • For fast moving trains carrying large numbers of passengers, mobile networks can struggle to deliver continuity of service for so many mobile devices needing to be rapidly handed from cell to cell.
  • The amount of radio spectrum in the hands of mobile operators, especially spectrum suited to macro networks, is likely to be insufficient to support all user devices on a busy intercity train in addition to their non-railway users.
  • The need to deploy all mobile networks in the rail corridor, even if using a “Neutral Host” distributed antenna system (ie Boldyn on LUL), may be economically suboptimal compared to a dedicated track to train network connection. 

Looking to the fragmented initiatives over two decades, there has been no clear, obvious and accountable challenge owner in government. For many years the challenge has circulated DfT, DCMS (DSIT), NIC and their respective industry bodies and agencies (eg Ofcom, ORR, Network Rail, RSSB etc) with no absolute accountability. This has resulted in no clear and consistent mandate or obligation being placed upon the telecoms or rail industries (ie mobile operators, Network Rail or passenger train operators) to deliver a meaningful connectivity service to train passengers. As previously discussed, the advent of Great British Railways may present an opportunity of a guiding/directing mind but is likely to require the evidence of benefits described in this case study.

Where on-train connectivity is delivered via WiFi (deployments funded both by train-operator and government grant) these almost exclusively use public mobile data services to connect the WiFi system back to the Internet. This has added significant costs for the train operator which have been difficult to recover from value-add services (eg paid-for WiFi, first-class upgrades etc) or ticket price increases. This often results in service rations and quotas linked to contracts between train and mobile operators, which manifest themselves as a poor WiFi service to the passenger. Future initiatives will need to look at both the deployment (cost and capability) and operation (cost and experience) aspects of delivering the on-train connectivity experience.
