  • ELECTRIC DOUBLE-DECKER MULTIPLE UNIT KISS Aeroexpress, Russia
    ELECTRIC DOUBLE-DECKER MULTIPLE UNIT KISS Aeroexpress, Russia In May 2013, Russian rail company Aeroexpress ordered 11 KISS electric double-decker multiple units from Stadler. These included 9 six-car and 2 four-car trainsets. The trains, named «Eurasia» by Aeroexpress, are used on the three lines between Moscow city centre and the airports. With the purchase of the new trains, Aeroexpress meets the fast-growing demands for public transport capacity and offers its passengers new standards in comfort. The four-car versions have 396 seats, while the six-car models have 700, of which 84 are in business class. They fulfil the Russian standards and, at the same time, set new standards for commuter traffic in Russia. Air conditioning in the passenger compartments and drivers‘ cabs is adapted to the tough climatic conditions in Russia. The design of the interior is bright and passenger-friendly. A modern passenger information system provides travellers with relevant information. www.stadlerrail.com Stadler Rail Group CJSC Stadler Minsk Ernst-Stadler-Strasse 1 Zavodskaja Street 47 CH-9565 Bussnang 222750 Fanipol Phone +41 71 626 21 20 Dzerhzhinsk District [email protected] Region of Minsk Phone +375 17 16 22 410 [email protected] Technical features Vehicle data Technology – Lightweight car bodies in integral aluminium design in line with Customer Aeroexpress the latest standards for crashworthiness (EN 15227) and car Lines serviced Moscow airport link body strength (EN 12663) – Vehicle body made of extruded aluminium sections

  • ELECTRIC DOUBLE-DECKER MULTIPLE UNIT KISS Georgian Railway (GR), Georgia
    ELECTRIC DOUBLE-DECKER MULTIPLE UNIT KISS Georgian Railway (GR), Georgia In April 2016 Stadler and Georgian Railway signed an agreement for four-car KISS EMUs. The trains are used on express services between Tbilisi and the Black Sea resorts of Batumi, Kobuleti and Ureki, without any other intermediate stops. The acquisition is a notable one for Georgian Railway, since the 160 km/h KISSes are the first most modern passenger trains, of west European design, in the operator's fleet. They are fully compliant with European safety standards, and are the very first double deck trains in Georgia. These four car trains satisfy the growing demand for high-quality public transport and offer passengers great comfort in a bright and spacious interior, comfortable seats, full air conditioning, passenger information system, WiFi and other functions. One train has 396 seats, including 84 in business class, and a total capacity of 919 passengers.

In addition the Trust launched an further range of covenants for young people, companies and for those wishing to contribute to the project after their death. The A1 Steam Locomotive Trust is raising £1.6m to build a new Peppercorn class A1 No. 60163 Tornado at its Darlington Locomotive Works through Deeds of Covenant for ‘the price of a pint of beer a week’ (£1.25 in the North East when the project was launched in 1990). Although Tornado is around 50% complete by weight, if the Trust cannot raise another £700,000 quickly it could be up to another 4 years until the new steam locomotive can be completed at current rates of growth in income.

  • Rack-Railway Locomotives of the Swiss Mountain Railways
    JULY1911. RACK-RAILWAY LOCOMOTIVES OF THE SWISS MOUNTAIN RAILWAYS. BY MR. J. WEBER, MANAGINGDIRECTOR, AND MR. S. ABT, WORKSENGINEER, OF THE SWISS LOCOMOTIVEAND- ENGINE WORKS, WINTERTHUR. [Translated from the Gennan.] General.-The first rack-railway locomotive was tested by John Blenkinsop on the 12th August 1811, that is to say almost one hundred years ago, on the Middleton Mineral Line, near Leeds. On the outside of one rail corrugated teeth were cast, into which the driving wheel geared, which wlts outside the carrying wheel. Rimber in 1831 in America proposed placing a rack in the centre between the two rails, and this idea was carried out by Cathcart in 1847 on the Madison-Indianapolis Railway. Blenkinsop did not know that the friction between the rail and the wheel was sufficient to provide for the progress of the locomotive and the traction of the train. It was not until 1813 NoTE.-For other particulars of these railways, see Paper on Electric Traction in Switzerland, by itlr. E. Huber-Stockar (page 449).

JGLY1011. that Blackett, owner of the pits at Wylam, showed that this was possible, and subsequently Stephenson built his locomotive as a purely adhesive engine. Owing to the rapid and enormous development of the railways, many improvements were made in I 'comotive construction, and great progress was attained. The necessity of dealing with heavy trains and lines with very steep gradients naturally called for heavy locomotives with an increased number of coupled wheels, which required special designs in the carrying parts of the locomotive in order that they might be in a position safely to deal with curves, at the same time offering the lowest resistance.

  • The Rocket Locomotive Project
    Michael R Bailey and John P Glithero Learning through industrial archaeology: the Rocket locomotive project Introduction In the quest for greater understanding of the history of engineering and technology, the artefacts in the world's museums of science, tech­ nology and industry provide a most important resource. A thorough survey of these artefacts, together with historical and technical research surrounding their history, can advance our knowledge of the development of materials, manufacturing methods and maintenance practices. The importance of this resource is apparent because engineers and technologists often failed to record their approach to design and manufacturing methods, and their understanding of materials. Furthermore, the accumulated knowledge and skills of the tradesmen were rarely recorded, being transmitted from master to apprentice, each generation developing the skills of its forebears. Recent calls to pursue a greater understanding of artefacts, through survey, I have led to several research studies in the 1990s, some leading to conservation and restoration projects by the authors, summaries of which have recently been published.2 The most comprehensive of these studies was carried out by the authors at the National Railway Museum in York during 1999, on George and Robert Stephenson's Rocket locomotive of 1829 (Colour plate 1). This preceded its return to the Science Museum in London for display in its new Making the Modern WOrld gallery. The study was supervised by Richard Gibbon, Head of Engineering at the National

  • “ the CONSTRUCTION of STEAM RAIL MOTORS,”
    [No 79.] G.W.R. Mechanics’ Institution. SWINDON ENGINEERING SOCIETY. TRANSACTIONS, 1906-7 INTERMEDIATE MEETING.– Tuesday, March 12th, 1906. Chairman– Mr. G. H. Burrows, Assoc.M.I.Mech.E. “THE CONSTRUCTION of STEAM RAIL MOTORS,” by A. H. NASH (Member). With Discussion The success attending the use of Rail Motor Cars as a convenient means of transport, and their utility in suburban traffic as competitors with rate-aided electric trams, has been fully established. It is the object of this paper to explain the construction of the steam motors at present in use upon the Great Western Railway. The rail motors designed and constructed at Swindon, though not the pioneers on English railways, are acknowledged to be the finest in Europe. They have reached a state of perfection rarely attained on any other railway in the world. To fulfil the object for which rail motor cars were primarily designed, they must be able to satisfactorily accomplish varying speeds up to 40 miles per hour ; they must also possess the power of rapid acceleration, and be able to haul one or two trailer cars during rush hours, and if necessary, to do this continuously. To these requirements may be added sundry shunting operations in yards where spare locomotives are not kept. The Traffic Department of a railway will do its best to obtain the whole of these requirements. The Author has heard of a rail motor hauling seven or eight horse boxes and two or three coal wagons in addition to its full complement of passengers. Under such conditions it is not to be wondered at that these cars occasionally require a rest ; yet one car regularly runs 220 miles a day — a performance worthy of one of the 4-6-0 class of engines.
