It complements the Landscape Character Type descriptions of the 2019 dataset. The original character assessment reports, part of a series of 30, mostly for a local authority area, included a “Background Chapter” on the formation of the landscape. These documents have been revised because feedback said they are useful, despite the fact that other sources of information are now readily available on the internet, unlike in the 1990’s when the first versions were produced. The content of the chapters varied considerably between the reports, and it has been restructured into a more standard format: Introduction, Physical Influences and Human Influences for all areas; and Cultural Influences sections for the majority. Some content variation still remains as the documents have been revised rather than rewritten, The information has been updated with input from the relevant Local Authorities. The historic and cultural aspects have been reviewed and updated by Historic Environment Scotland. Gaps in information have been filled where possible.

Tourism in Scotland is both an important and extensive land use and a major contributor to Gross Domestic Product. In 2005, it is estimated that Scotland received around 10.5 million visitors from outside Scotland. Just over 76% of the visits originated in the rest of the United Kingdom, with the remainder having an international origin. 2. Tourism relies heavily on passenger transport both to access the destination, but also to travel around within it. However, there has been a lack of attention to the internal accessibility of Scotland from the visitor perspective. Whilst some attempts have been suggested and prioritised for facilitating tourists’ travel around Scotland, such efforts are mainly undertaken by tourism organisations throughout Scotland, whose ultimate power to enable changes to transport systems is largely limited to lobbying. Moreover, without a clear picture of how accessible Scotland is internally as a destination, or of the transport demands of visitors in terms of internal accessibility, any measures taken to enhance visitor transportation remain largely uninformed.

    Railway Ramblings Issue 131 June 2021 The monthly newsletter of the RCTS Hitchin & Welwyn Garden City Branch Forthcoming Meetings This month we continue with Zoom virtual meetings. But, starting in July, we are expecting to be in a position to restart “traditional” meetings, continuing without a summer break, to the end of the year. We do need to know if you would want to attend – please see “Chairman’s Platform” for how to let us know. Assuming we go ahead, there will be a number of practical things to be aware of and these will be set out in next month’s issue. As you all know, progress back to “normality” is controlled by our Government and our plans could still need changing at relatively short notice. Our next virtual meeting is 8th June: for details see “Forthcoming Events”. From the Photo Album A previously published photo taken by Adrian White. May he rest in peace. TPE IEP 802210 passing Welwyn North on 29 August 2019 Photo: Adrian White If you have photos (old or new) that you are willing to share with other members please supply them, with a suitable caption, to the Editor, John Dossett, at [email protected]. They should be your photographs! 1 Chairman’s Platform As I was about to send out the May Railway Ramblings, I received some sad news: Adrian White (frequent attendee, speaker and railway photographer) had died in hospital on Wednesday 21st April. He had rung me from his hospital bed on Sunday 18th to apologise for not being well enough to fulfil his next booking with us at the RCTS! Not only that, but he gave me contact details of 3 people who had agreed to deputise for him.

  • Lochalsh Line Is One of the Most Scenic Train Recommended Activities in Plockton Comes Calum's Seal Trips the Shortest of Walks)
    The Falls of Glomach (2) are reputed to be the highest falls in the country and can be accessed via Dorusduain (while the walk is moderate it is advisable to leave plenty of time as it is roughly 2.5 miles uphill). Conveniently situated by the Glen Shiel road is the Jac-O-Bite Restaurant (3) – don't let the exterior fool you, the restaurant may have the appearance of a road-side diner but has attracted excellent reviews. Also nearby Shiel Bridge is Glenshiel Ponytracking (4) (suitable for children aged 6 and above). Day trips around & about Lochcarron There are also several sights to see on the road over to Glenelg. The Bernera Barracks (1) are a relic of the Hanoverian period dating back to around 1717; one of four barracks constructed in the Highlands following the initial Jacobite risings. Glen Shiel is also the location of one of the major battles of the 1719 Jacobite uprising and in the aftermath of the '45 uprising Charles Stewart (a.k.a. Bonnie Prince Charlie) spent part of the summer hiding in the Glen.

  • The Coastal Wave and Overtopping Forecast Service for Network Rail Scotland Nigel Tozer1, Tim Pullen1 Andy Saulter2, Helen Kendall2
    Nigel Tozer, Tim Pullen, Andy Saulter, Helen Kendall The coastal wave and overtopping forecast service for Network Rail Scotland Nigel Tozer1, Tim Pullen1 Andy Saulter2, Helen Kendall2 1 HR Wallingford, Howbery Park, Wallingford, Oxfordshire OX10 8BA, UK 2 Met Office, Exeter, UK Presented at the ICE Coasts, Marine Structures and Breakwaters conference, Edinburgh, September 2013 Abstract An operational coastal forecasting service has been provided to Network Rail in Scotland by the Met Office and HR Wallingford since 2004 for the management of sea defence inspections. This paper provides a background to the service, the modelling approach and some examples that illustrate the value of the service. Introduction Network Rail’s assets include approximately 150 miles of sea defences around the coast and a significant proportion of these are located within Scotland under the responsibility of Network Rail Scotland (NRS). As illustrated in Figure 1, which shows the sea defences and track at Saltcoats in the Firth of Clyde, many of the coastal and estuarial defences are exposed to adverse weather and sea conditions. Guidelines from the rail inspectorate (The Office of Rail Regulation) require NRS to carry out timely inspections of defences that protect the track from flooding, exceptional tides or gales. These inspections are intended to supplement routine line inspections and annual structural inspections with the intention of reducing the potential damage to the network and risk to rail traffic by responding early to signs of damage. HRPP575 1 Nigel Tozer, Tim Pullen, Andy Saulter, Helen Kendall Figure 1 Rail line at Saltcoats showing heavy wave overtopping (Source Network Rail Scotland) Since January 2004 the Met Office, in collaboration with HR Wallingford, have provided NRS with forecasts of severe weather conditions along sections of the Scottish network’s more exposed and highest priority sea defences.

  • Kyle of Lochalsh Line, Uk Kyle of Lochalsh Line
    Slope Protection KYLE OF LOCHALSH LINE, UK KYLE OF LOCHALSH LINE Slope Protection Project Kyle of Lochalsh Line Location Kyle of Lochash Country/Region United Kingdom Year of installation 2001 Customer Network Rail Infrastructure Ltd. Engineering Donaldson Associates Ltd. Contractor BAM Ritchies / BAM Nuttall Ltd. Initial situation A series of exposed rock face cuttings, on the railway line between Dingwall and Kyle of Lochalsh in North West Scotland, were in need of active stabilisation to protect the railway line. This was typically required in areas where the rock mass structure dipped out of the cutting leading to the potential for wedge and planar failure in addition to small rockfalls. Where the structure of the rock mass was less critical and the risk to railway operations resulted only from rockfalls drape netting was employed. Description TECCO® G65/3 was used in conjunction with rockbolts to stabilise rock cuttings. Individual blocks were bolted in addition to the mesh which was contoured around the face and blocks. Photos illustrate a cutting where the slope on the left side required active support of relatively large and potentially unstable blocks where TECCO ® G65/3 together with TECCO® SYSTEM³ spike plates was used. On the opposite side of the cutting the main risk was from falls of small blocks and here a drape system was employed.
