Luminescence dating researchers benefit from many community-led software packages. These packages assist with data reduction, statistical modeling, calculation of dosimetric values, and plot production. Yet few resources are simultaneously intuitive, meant for simulating the reduction and growth of luminescence signals, and accessible to non-specialists. The Luminescence Sample Simulator (LuSS) is an application with a graphical user interface that simulates how apparent age and fractional saturation respond to three key scenarios in luminescence dating: sunlight exposure, heat exposure, and burial. Users can simulate these scenarios for an individual cobble or sand grain, or for a population of 100 sand grains. The underlying kinetic parameters can be adjusted manually or taken from a built-in library of published values. Plots of apparent age histograms, luminescence depth profiles, or fractional saturation and apparent age histories are visualized and can be exported. LuSS is written in MATLAB and can operate as a free-to-use, standalone application, or as an app within an existing MATLAB installation. A typical user workflow and three worked examples show how LuSS can model luminescence signal evolution in response to geologic scenarios. Limitations of LuSS include its inability to capture athermal fading or between-grain variability in geologic dose rate or sensitivity.
Britain’s railways are broken. They no longer serve the needs of passengers or the general public. Train services are unreliable, too often delayed, too expensive and complex to use, and marred by strikes. This book takes the reader on a journey to discover how years of under-funding and privatisation have deprived the public of a usable rail system. It is only through understanding how Britain’s rail system has been broken that we can know how to fix it. As it shows, fixing the railways means going beyond simple demands such as ‘renationalise the railways’ and asking instead ‘what do we want the railways to be for’? It is only by attempting to answer this question that we can rebuild the rail system into something that genuinely meets people’s needs. The answer is far from straightforward, but this book argues that, if they are to be useful, the railways must be part of the solution to the twin crises of the climate emergency and social inequality. This means significant increases in government investment, but the current state of the railways stems largely from successive governments’ unwillingness to properly fund them, mostly to protect the wealthy from tax increases. Given the uneven distribution of political power in Britain and the rigidity of public policy, those who want to see the railways fixed have no choice but to fight to take rail policy out of the hands of the political and financial elite who have led us into this mess.
In recent years, the railways have been marred by long-running strikes, which have impacted significantly on rail services. The most impactful of the strikes have been a result of rail trade unions seeking to prevent the reduction of staff employed in running services, especially on-board staff such as guards and conductors. Since the mid-2000s, the majority of train operating companies have attempted to install ‘driver-only operation’ – services run without guards. To some, the militant response of the main union – the RMT – represents a bygone era of trade unionism and impacts unfairly on passengers. But this is to disregard important aspects of railway history and politics. Indeed, one of the principal motivations of privatisation was to decrease the collective organising power of rail workers, by fragmenting their bargaining power through outsourcing and franchising. However, despite being a disaster for many rail workers, privatisation has not been as successful in attacking the workforce as was originally hoped, and this is in no small part thanks to the democratisation of the RMT and its subsequent increased willingness to organise strikes and strike ballots. When rail workers go on strike, the rail companies they work for are compensated by the government for any loss of revenue that results. This explains the longevity of strikes – the determination and collective organisational capacity of rail workers has been up against the vast financial resources of the state. The chapter ends by showing that guards are very important for maintaining the accessibility of services.
This chapter addresses the problem of train service punctuality and reliability. It begins by showing that one of the main causes of delays is insufficient investment in infrastructure. Furthermore, it shows that privatisation was an exercise in attempting to bring private finance into the provision of infrastructure to replace public investment. This, however, led to a financial disaster in two parts: firstly, with the collapse of the privatised infrastructure provider Railtrack after the Hatfield rail crash, and secondly, following the renationalisation of its successor, Network Rail. Although the two companies were structured very differently, they shared a common fundamental fault – they both needed to reward private providers of finance, which only served to increase the costs of infrastructure provision in the long term, thus starving the railway infrastructure of the investment it needed to expand to meet demand. The chapter then goes on to show that another major cause of delays is shortages of train crew, arguing that the system of franchising, created by privatisation, is largely to blame. Franchising encourages train operating companies to cut labour costs, which leads to fewer staff being available than are needed to run services. Finally, the fragmentation of operations that privatisation creates leads to operational incoherence, which further adds to the likelihood of service delays.
This chapter discusses the prospects for fixing Britain’s rail system. It begins by noting that current elite thinking on reforms has nothing to say about what the purpose of the railways is in early to mid-twenty-first-century Britain. It is only with a clear idea of that in mind that we can possibly understand what the most appropriate levels and systems of funding and management should be. The chapter argues that, in order to maintain relevance, the railways will have to play their part in averting climate catastrophe, while also reducing social inequalities, in a ‘just transition’. This can work only if rail is seen as dependent on and part of a wider transport system that needs to decarbonise, and serves the needs of the economy in which it functions. That can only be achieved by a new public body that is responsible for coordinating a just transition across transport modes and sectors – a National Climate Service. Transport decarbonisation means a mixture of demand reduction, ‘modal shift’ and the closing down of transport systems that are impossible to decarbonise. The rail system will need to step in to replace journeys made by the most polluting modes. The railways must be fully electrified and must expand to meet demand (although expansion is limited by the ‘embodied carbon’ of construction). They should be made much cheaper to use. These changes are unlikely without big social movements, which are needed to wrest political power from the privatising policy elite which broke the railways in the first place.
Given the problems outlined so far, how can passengers hold the railways to account? Partly in tacit recognition of huge passenger dissatisfaction, the rail industry has introduced a range of compensation schemes for delays. However, train operating companies pocket the difference between the compensation provided to them by Network Rail and the huge amount of compensation unclaimed by passengers, and this provides little incentive for improvement. Compensation culture also encourages passengers to see the broken railways as a personal, consumer rights problem, rather than a structural problem with collective impacts. Compensation does not fix the railways. For that, collective political organisation by passengers is required. Passenger campaigns have enjoyed some success over the years, most notably in making rail line closures politically toxic. However, the more traditional campaigns tend to be characterised by voluntarism and conservatism. They bring undoubted improvements to the railways, especially in the upkeep of smaller stations, but are ineffective in forcing more fundamental change. Recently, a range of smaller movements have achieved victories, some of which have cost the rail establishment dearly. These point to strategies and approaches – such as fare strikes and integrating campaigning across public transport modes – which, on a grander scale, could start to force the rail system to be fixed.
The chapter begins by showing that fares have increased massively since privatisation, but the extent of that increase has been partially obscured by the government’s decision to use the largely defunct RPI measure of inflation for the purposes of fare regulation. According to standard measures of inflation, rail fares have risen even more steeply than is officially admitted. This is as a result of deliberate government policy, which has pushed the costs of privatisation onto passengers The rail industry deliberately hides ways to get cheaper flexible tickets from view. Instead of promoting these options, train operating companies have invested in beefing up security to prevent ‘fare evasion’. This has caught many passengers who have made innocent mistakes with ticket purchasing in a trap, which demands that they pay hefty fines to avoid criminal prosecution. Given these problems, the rail industry is looking at reform to simplify the ticketing system. This seems welcome until one considers the small print, the effect of which will mean even higher fares for passengers on the lowest incomes. Finally, the privatisation of rolling stock has significantly increased the costs of providing rail services, adding yet more incentive for ticket price rises. Despite this, successive governments have eschewed the most financially sensible policy – of public, not-for-profit, rolling stock provision.
The Introduction introduces the setting for the book – a delayed train from London Euston – and the characters the author meets on the way. Meeting the other passengers reminds the author of the key questions that Britain’s broken railways poses to passengers, which this book seeks to answer. Before delving into the answers, the book provides a whistle-stop run-through of the railways’ history, which helps set up the exposition of recent developments in the main body of the book. This considers the railways’ evolution from private steam-operated services competing with each other (principally) for freight traffic, to the consolidation of the system as rapid expansion and competition proved economically unviable, to temporary nationalisation under war governments and, later, the creation of British Rail, as the railways became a secondary, state-subsidised transport system, subservient to investment in, and use of, roads by motor traffic. The Introduction ends with the privatisation of British Railways in the mid-1990s. Throughout, it is demonstrated that all post-war governments have had a problematic relationship with railway subsidy, and the unrealistic desire to make railways operate on commercial lines has mired rail policymaking to this day, leading to a rolling and ever-increasing crisis of provision.
Mobility was central to imperialism, from the human movements entailed in exploration, travel, and migration, to the information, communications and commodity flows vital to trade, science, governance and military power. While historians have written on exploration, commerce, imperial transport and communications networks, and the movements of slaves, soldiers, and scientists, few have reflected upon the social, cultural, economic and political significance of mobile practices, subjects, and infrastructures that underpin imperial networks, or examined the qualities of movement valued by imperial powers and agents at different times. This collection explores the intersection of debates on imperial relations, colonialism and empire with emerging work on mobility. In doing this, it traces how the movements of people, representations, and commodities helped to constitute empires.The collection examines things that moved across the British Empire, including, objects and ideas, as well as the efforts made to prevent and govern these movements. It also considers the systems, networks and infrastructures that enabled imperial mobilities to happen, and things that went wrong. The collection ranges from the late eighteenth century to the early twentieth century, a period that witnessed the eclipse of the ‘first’ British Empire in North America and the Caribbean, and the expansion of an imperial presence in Asia and Africa, and ends with the empire at its greatest extent in the interwar period. Geographically, it encompasses much of the territorial breadth of the British Empire in Africa, Asia, Australasia and the Caribbean. It also ranges off-shore and into the air.
This chapter explores the salience of mobility to an understanding of visual culture in the colonial period, focusing in particular on the works of art produced on board Matthew Flinders's inaugural circumnavigation of Australia between 1801 and 1803: by British landscape painter William Westall (1781–1850) and Austrian botanical artist Ferdinand Bauer (1760–1826). Mobility was a strategic advantage for such artists in providing new material to record both for Enlightenment science and a broader European public; yet it also presented an array of logistical, aesthetic and philosophical challenges. During and following the voyage an enormous number of pencil sketches, and subsequent watercolours, prints and oil paintings were produced to assist with the mapping and classifying missions of the voyage. Mobility, of course, was at the heart of this endeavour, and had at least since the Renaissance been equated with the pursuit of knowledge. Yet what I argue here is that in many senses mobility was utterly at odds not only with the practicalities of producing works of art under such trying circumstances, but more significantly, with the scientific demands made of the voyager artist; namely, precision and immutability.
