  • The Carrying Trade and the First Railways in England, C1750-C1850
    The Carrying Trade and the First Railways in England, c1750-c1850 Carolyn Dougherty PhD University of York Railway Studies November 2018 Abstract Transport and economic historians generally consider the change from moving goods principally on roads, inland waterways and coastal ships to moving them principally on railways as inevitable, unproblematic, and the result of technological improvements. While the benefits of rail travel were so clear that most other modes of passenger transport disappeared once rail service was introduced, railway goods transport did not offer as obvious an improvement over the existing goods transport network, known as the carrying trade. Initially most railways were open to the carrying trade, but by the 1840s railway companies began to provide goods carriage and exclude carriers from their lines. The resulting conflict over how, and by whom, goods would be transported on railways, known as the carrying question, lasted more than a decade, and railway companies did not come to dominate domestic goods carriage until the 1850s. In this study I develop a fuller picture of the carrying trade than currently exists, highlighting its multimodal collaborative structure and setting it within the ‘sociable economy’ of late eighteenth- and early nineteenth-century England. I contrast this economy with the business model of joint-stock companies, including railway companies, and investigate responses to the business practices of these companies. I analyse the debate over railway company goods carriage, and identify changes in goods transport resulting from its introduction. Finally, I describe the development and outcome of the carrying question, showing that railway companies faced resistance to their attempts to control goods carriage on rail lines not only from the carrying trade but also from customers of goods transport, the government and the general public.

    EDUCATING ABOUT TRANSPORT HISTORY: DEVELOPING OBJECT-LEARNING PROGRAMS AT THE LONDON TRANSPORT MUSEUM An Interactive Qualifying Project Report submitted to the Faculty of the Worcester Polytechnic Institute, in partial fulfillment of the Bachelor of Science degree in cooperation with the London Transport Museum Submitted by: Andrew Barth Luke Perreault Ryan Santos Woodrow Shattuck Project Advisors: Professor Zhikun Hou Professor Wesley Mott Sponsor Liason: Elizabeth Poulter Submitted on: 19 June 2013 Abstract Incorporating engineering objects into educational outreach programs is a proven means to excite students about transport engineering. Grounded in theories of museum education and object-based learning, we offer means to help the London Transport Museum (LTM) achieve this mission: narratives on various disciplines of transport engineering, an engineering object catalog, and “toolkits” for using objects in engineering education programs. These resources and suggestions for acquiring new engineering objects are designed to enhance current and future program development. i Table of Contents Abstract ............................................................................................................................................ i Authorship...................................................................................................................................... iv Table of Figures ............................................................................................................................. vi Acknowledgements

  • History of Transport
    History of Transport Did you know that a very important invention happened a very long time ago? In 3500BC, a wheel was attached to a cart for the first time. This invention meant that people could use a cart to carry food that they had gathered instead of having to carry it by hand. People could use the cart to carry items for longer distances. In 1783, a man called Jean-François Pilâtre de Rozier flew in a hot air balloon for the first time. This is a hot air balloon. Jean-François worked as a French chemistry and physics teacher. He knew that the people who flew in the hot air balloon for the first time would be remembered forever. King Louis XVI thought that two criminals should be put into the hot air balloon, but Jean-François disagreed. He managed to convince King Louis XVI to let him be the first person to fly. In 1785, Jean-François tried to cross the English Channel in a hot air balloon. The balloon deflated during the flight and crashed. Jean-François was killed in this accident. A man called George Stephenson invented the first steam-powered engine in 1814. He called the engine ‘Blucher’. Blucher’s first job was to carry eight coal wagons along an uphill track. Blucher was so successful that Stephenson ended up building another sixteen engines. German inventor Karl von Drais invented something that he called the ‘Laufmaschine’, which means ‘running machine’. It looked a lot like a bicycle, but something was missing! Can you see what is missing from this bicycle invention? This invention had two wheels and handles at the front of it for steering, but it had no pedals.

Urban ground transport includes the key transport infrastructure like roads, sidewalks, bridges, railway tracks, fuelling stations, workshops, car parks etc. Then there are the modes of transport like cars, motorcycles, para transit like rickshaws, wagons, and trucks and buses, trains. Nowadays there is a strong focus on promoting walking and bicycling – modes of mobility that are termed as ‘Non-Motorized Transport (NMT). Modern forms of transport were a by-product of the age of industrialization when for transporting the mass produced goods and growing population, rail systems were introduced and the factory towns or the modern industrial cities were shaped by the automobile.

    The future for interurban passenger transport M a d r i d Bringing citizens closer together 1 8 t h International Symposium on Transport Economics and Policy The future for interurban passenger transport Bringing citizens closer together Economic growth, trade and the concentration of population in large cities will intensify demand for interurban transport services. Concurrently, the need to manage environmental impacts effectively will increase. How successful we are in coping with demand will depend on our ability to innovate, to manage congestion, and The future to improve the quality of transport services. Technological and regulatory innovation will shape the future of transport. The Symposium brought together leading transport researchers from for interurban around the world to explore the future for interurban passenger transport. A first set of papers investigates what drives demand for interurban passenger transport and infers how it may evolve in the passenger future. The remaining papers investigate transport policy issues that emerge as key challenges: when to invest in high-speed rail, how to regulate to ensure efficient operation, how to assign infrastructure to transport different types of users, and how to control transport’s environmental footprint by managing modal split and improving modal performance.
