  • Response to the Consultation Document
    RESPONSE TO THE CONSULTATION DOCUMENT: “A new approach to rail passenger services in London and the South East” Introduction 1. This response from concentrates on matters affecting the users of the four stations on the Greenwich line (Deptford, Greenwich, Maze Hill, and Westcombe Park). We do not comment on matters that only affect other areas of London and the South East. 2. Our response also takes account of the announcement made on 21 January 2016 that responsibility “for inner London rail services that operate wholly or mainly within Greater London” will transfer to TfL. The precise services or geographical area are not specified, but, for the purposes of our response about services on this line, we have assumed it includes all our trains except for a few peak hour services that extend beyond Dartford 3. Latest ORR figures of estimated station usage show that, in 2014/15, there were 7.1m users of these four stations, an increase of 5.5% over the previous year. This number will certainly continue to rise as a result of large housing developments in the Greenwich and Deptford area. Since 2014, 7,080 new homes have either been built, or are being built, in the vicinity of at least one of the four stations. A further 15,000 are planned for North Greenwich which will impact on Maze Hill and Westcombe Park. Greenwich is a major tourist destination for London and home to the University of Greenwich and Trinity/Laban and other educational establishments, with over 38,000 students. The proposed cruise liner terminal at Enderby’s wharf will also add pressure.

  • Southeastern Trains Map Pdf
    Southeastern trains map pdf Continue Routes encoded by three London terminals. The best experience from several routes to London. Offer the Priorat to be dumped from Dover as it was a long time since there was no Marine Corps, Harbor or City Station. London Bridge is completely open. With work on the redevelopment of London Bridge. Not 45o lines to the right of the map. It's a bad map type that makes something that's just on earth unrecognizable. Since when did Kent look like this - with a club leg? The map takes straight and straight south-east main lines (London - Tonbridge - Hastings and Tonbridge - Ashford - Dover) in a tangled few corners. Tonbridge - Dover line arrow straight (superb piece of engineering Cubitt) - why put four bends in it? Not only that, but it's so boring you can die of depression just by looking at it. Pointless headline. Buffers in London termini, but not elsewhere. Poor geographical relations between London terminals. Strange and gloomy flower-breeding - not typical (and two dark brown colors from Charing Cross). Lines do not intersect correctly, for example in Ebbsfleet. No statement on the choice of station (stations disappear along the north Kent coast). The routes are colored. Includes Thameslink to Bedford as a co-service. Poor presentation of Javelin's new fast services: unclear around Gravesend showing Eurostar passes; The North Kent lines stretched too far to the right making Javelin/Eurostar very indirect. The map below was added without a rethink. Some very small type there. You may not recognize this important route on this map.

In this issue we cover our new on-board entertainment system Motion – now available on a Southeastern train near you. We also take a closer look at the £30 million revamp of our train fleet, reveal our favourite hidden gems in Ashford and Margate, and get to grips with the story behind “leaves on the line”. Contents We know that it’s been a tricky year for rail passengers, and this was reflected in the Spring 2018 National Rail Passenger Survey results. We saw our score drop to 75 per cent from a record-breaking 81 per cent the previous year. We’re working hard to get our scores back to where they were and know that punctuality and reliability are what matter most to you. A total of 35 per cent of the survey’s respondents had been delayed – many during the severe winter weather in February and March, which caused significant damage to our trains.

  • Introduction
    Introduction Shortly before his death in 1965 Herbert Morrison, former leader of the London County Council and Cabinet minister, looked back across a distinguished London life to the place where he had launched his career: ‘Woolwich has got a character of its own’, he reflected. ‘It doesn’t quite feel that it’s part of London. It feels it’s a town, almost a provincial town.’1 Woolwich was then at a cusp. Ahead lay devastating losses, of municipal identity when the Metropolitan Borough of Woolwich became a part of the London Borough of Greenwich, and of great manufacturing industries, so causing employment and prosperity River Thames to tumble. Fortunately for Morrison, he did not witness the fall. His Woolwich was a place that through more than four centuries had proudly anchored the nation’s navy and military and acquired a centrifugal dynamic of its own. All the while it was also a satellite of London. When metropolitan boundaries were 1 defined in 1888 they were contorted to embrace an unmistakably urban Woolwich. 3 Woolwich attracted early settlement and river crossings because the physical geography of the Thames 2 6 basin made the locality unusually accessible. Henry VIII’s decision in 1512 to make great warships here cast the dice for the special nature of subsequent development. By the 1720s Woolwich had long been, 4 as Daniel Defoe put it, ‘wholly taken up by, and in a manner raised from, the yards, and public works, erected there for the public service’.2 Dockyard, ordnance and artillery made up the local lexicon.

  • Case Study: ETCS Testing – Thameslink Core Area
    Case Study: ETCS Testing – Thameslink Core Area Class 700s ETCS testing took place during mid-week nights through the Thameslink Core Area, while adjacent lines were open to service traffic, in preparation for ATO to be enabled Class 700 unit ETCS testing is undertaken as part of the Thameslink Programme works to upgrade the signalling in the Core Area for European Train Control System (ETCS). The Class 700 unit is fitted with ETCS equipment for testing the associated on-train and track-side equipment that has been installed in the Core (mainly track-side balises). The ETCS signalling system, once operational, provides a high level of safety integrity which will then enable Automatic Train Operation (ATO). Ultimately the consistent acceleration/braking and dwell times provided by ATO can reliably deliver 24 trains per hour through the Core Area. Overview of ETCS Testing Arrangements • As per previous arrangements all testing will be undertaken within the T3 possessions. The only difference to previous testing is that the testing will take place over mid-week nights with the adjacent line open to service traffic. All instructions and procedures are still applicable. • The possession will be taken around the test train (Kentish Town, St Pancras or Blackfriars). When in the initial weeks the signaller at Three Bridges ROC and West Hampstead will be required to set routes as requested by the TIC via the ES. • As per the WON the possession can be given up around the test train at a signal location agreed between the Signaller and PICOP/ES. • Separate Signal Box Instructions will be issued to West Hampstead PSB and TBROC to detail the arrangements.
