Brussels Metro to Grow As Pre-Metro Shrinks
BRUSSELS METRO TO GROW … AS PRE-METRO SHRINKS by Geoffrey Skelsey The recent announcement that preliminary work was to start on the extension of Brussels Metro line 3, and the conversion to Metro operation of the existing tram-worked pre-metro line, makes it timely to review the story of the line, and of the pre-metro concept. This will be the latest development in a conversion programme which began in 1976 on line 1, followed in 1988 on line 2. THE BIRTH OF THE ‘PRE-METRO’. The pre-metro is often thought to have originated in Belgium and (West) Germany, but it is a sad reflection on a lack of impetus in British transport projects that amongst the earliest formulations of a system of tram subways linking segregated suburban feeder lines occurred in Leeds and Glasgow around the end of the Second World War. The Leeds transport manager, W. Vane Morland, after pre- war study tours in Sweden and Boston, drew up proposals in 1944 for intersecting tunnels below the city centre leading to a network of high-quality suburban tramways (or ‘light rail lines’ as they would now be called). The city went some way towards achieving the second part of the project, with ‘express’ tramways extending east and south of the city, and other planned, some of which were completed as late as 1949. Exploratory work was undertaken by the City Engineer, including trial borings for tunnels extending east-west and north-south, with a two-level interchange station below City Square. In 1948 Eric Fitzpayne, Glasgow’s enterprising transport manager, produced similar plans, with the important addition of proposals to reuse underexploited local railways with tram-type vehicles. -
On the Assessment of the Escalator Capacity in Metro Stations
U.P.B. Sci. Bull., Series D, Vol. 77, Iss. 4, 2015 ISSN 1454-2358 ON THE ASSESSMENT OF THE ESCALATOR CAPACITY IN METRO STATIONS. BUCHAREST METRO CASE STUDY Dorinela COSTESCU1, Ana-Maria CIOBÎCĂ2, Ionuţ-Sorin MITROI3 This paper presents some aspects related to the capacity assessment of design elements for metro stations, and focuses on the evaluation of escalator capacity, as long as it is considered both a restrictive element of total transfer capacity, and a qualitative element of the provided transport service. The paper takes into consideration a practical method for the estimation of the escalator capacity, which is mainly based on the user behaviour in occupancy of the escalator space. We use then this method to verify the provided capacity escalators in two main stations of the Bucharest metro and we reveal some needed actions in metro station design. Keywords: public transportation; escalator in metro terminal; transfer capacity. 1. Introduction The society of today is based upon large urban areas that have complexes transport networks, designed to serve the mobility needs of its citizens. The moving belt systems, especially escalators and moving walkways became more than a simple component of the urban layout, and passengers expects that those systems would simplify the walking trips in indoor spaces and also in outdoor public spaces. We can mention the case of large cities that have such functional facilities in outdoor public spaces throughout the year (e.g. Genève, Barcelona, etc.) In public transport stations, the moving belt systems are necessary design elements wherever elevation changes or there are longer distances, that must be travelled when carrying luggage. -

Threat Main Group: Bombing attack Threat Subgroup: EXP-01 small load (moving) City, Country: Brussels, Belgium Operator: STIB-MIVB Date/Period of time: 22 March 2016, during morning rush hour (7:58 - 9:11 a.m.) Category according to VDV Guideline: Catastrophe Location: Train (and Airport) Incident summary: Three coordinated suicide bombings occurred in Belgium: two at Brussels Airport in Zaventem and one at Maalbeek metro station, which is located near the European Commission headquarters in central Brussels. The bomb in the train (made from TATP explosives) exploded in the second carriage of a four carriage train as it started to leave the Maalbeek station. The attack took place about an hour after the bombings took place in Brussels Airport. The perpetrators belonged to the terrorist cell Islamic State (IS) of Iraq. Personal damage - number of injured persons: > 300 Personal damage - number of killed persons: 32 (20 pers. in metro station, 12 pers. in the metro) + 3 suicide bombers Material damage: No information available. Impact on operation: After the explosion in Maalbeek at 9:11 a.m., Brussels Metro was subsequently shut down at 09:27. The station Maalbeek was closed for over a month following the attacks. On 25 April 2016, the Maalbeek station reopened again. Impact on structure: Enormous damage of the train (and structure at the airport). Impact on user: After the explosion in the train, the driver immediately stopped the train and helped to evacuate the passengers. Cascading effect: After the attacks, the transport company in Brussels build an „ultra safety network“. Soon after the attacks, security was increased all over the world, particularly at airports, railway stations and other transport hubs (e.g. -

Alstom Salutes the Opening of the Bucharest Metro Line 5
PRESS RELEASE A new metro with a modern signaling solutions for safer and more efficient traffic Alstom salutes the opening of the Bucharest Metro Line 5 15 September 2020 – Alstom salutes the opening of Metro Line 5, an iconic metro project in Bucharest, for which the company delivered the first phase of the signalling system in a record time, less than a year for 10 stations. This project makes possible a new premiere for Alstom in Romania, with the Romania’s first CBTC (Communication-based Train Control)1 system. Once fully operational, it will bring 30% increase in line capacity while saving up to 30% of energy. © Alstom / A. Sulyok In the first phase of the project, Alstom has equipped the new line with One station on Line 5, ready to welcome passengers electronic interlocking, allowing it to operate safely using traditional signalling systems. The next phase will involve full implementation of modern signalling capabilities for optimised operation. Full CBTC will be the second stage of KEY FACTS project execution, and it will become fully operational once the line is equipped ⚫ First CBTC signalling system in with CBTC-enabled trains. Romania, once fully operational ⚫ 30% more capacity, with 30% less “This metro line will make a big difference in the lives of Bucharest’s people, energy consumption most notably the 360,000 ones living in the second largest district of our ⚫ Leading position of Alstom in the capital. Alstom is very proud to provide modern mobility solutions for a safe signalling market in Romania and efficient journey. Once the second stage will be completed, the CBTC signalling capabilities will bring Bucharest closer to cities like Amsterdam in taking advantage of urban mobility technology,” said Gabriel Stanciu, Alstom’s Managing Director for Romania, Bulgaria and Republic of Moldova. -
Assessment of AC Traction Substation Influence on Energy Quality in A
TECHNICAL TRANSACTIONS 12/2018 ELECTRICAL ENGINEERING DOI: 10.4467/2353737XCT.18.183.9671 SUBMISSION OF THE FINAL VERSION: 19/11/2018 Włodzimierz Jefimowski [email protected] Adam Szeląg Warsaw University of Technology, Power Engineering Institute, Electric Traction Division Assessment of AC traction substation influence on energy quality in a supplying grid Ocena oddziaływania podstacji trakcyjnej prądu przemiennego na jakość energii elektrycznej w sieci zasilającej Abstract This article presents investigations performed on a 25 kV AC system with a Scott transformer simulation model. The model includes an energy quality parameter calculation algorithm with consideration to the train timetable. The simulation results enable an analysis of the energy quality parameters at the point of connection of the traction substation to the supplying grid. The presented tool enables the simultaneous calculation of voltage unbalance and harmonic content. The article presents the results of the energy quality analysis at the substation connection point for the specific location. The simulation results of the energy quality parameters are appraised on the basis of standard EN 50160:2010. The tool may prove helpful in the process of designing electrification systems, especially in the choice of traction transformer and power electronics device mitigating an imbalance and harmonic impact.
