Dual Rated Speeds Escalator in Rapid Transit System with Extended Ramping Up and Down KC Gan, LF Cai, SC Cheah, Hadi Wijaya, Melvyn Thong Land Transport Authority, Singapore Keywords: Dual rated speeds, automatic switching, rapid transit system, acceleration, ramping up, ramping down, vibration, jerkiness. Abstract. To cater for different needs of escalator operating speeds in rapid transit systems (i.e. higher rated speed of 0.75m/s during peak hours is for effective discharging of passengers while slower rated speed of 0.50m/s during off-peak hours is for elderly passengers), we have introduced the dual rated speed escalator. Conventionally, the switching between 2 rated speeds can be done either manually through a key switch or automatically when no passengers are detected on the escalators at pre-set timing. However, there is a possibility of not being able to change speed if there are constant passengers coming into the rapid transit station, taking the escalators. Therefore, this shortcoming will be overcome by setting up a schedule timetable to do the safe switching of escalator rated speeds with passengers riding on the escalators with extended ramping up and down without comprising any safety requirements. This paper presents the case studies conducted on an existing station where a performance–based approach was adopted. The timing for the speed ramping up/down between the 2 rated speeds has been increased to 30 seconds in order to reduce the acceleration which results in minimizing the acceleration (vibration) and the rate of change of this acceleration (jerk). The objective is to ensure that the passenger’s perception are imperceptible and do not experience any abnormal and sudden change of vibration and jerk during the switching of dual rated speeds with extended ramping up and down. -

Comparison Between Bus Rapid Transit and Light-Rail Transit Systems: a Multi-Criteria Decision Analysis Approach
Urban Transport XXIII 143 COMPARISON BETWEEN BUS RAPID TRANSIT AND LIGHT-RAIL TRANSIT SYSTEMS: A MULTI-CRITERIA DECISION ANALYSIS APPROACH MARÍA EUGENIA LÓPEZ LAMBAS1, NADIA GIUFFRIDA2, MATTEO IGNACCOLO2 & GIUSEPPE INTURRI2 1TRANSyT, Transport Research Centre, Universidad Politécnica de Madrid, Spain 2Department of Civil Engineering and Architecture (DICAR), University of Catania, Italy ABSTRACT The construction choice between two different transport systems in urban areas, as in the case of Light-Rail Transit (LRT) and Bus Rapid Transit (BRT) solutions, is often performed on the basis of cost-benefit analysis and geometrical constraints due to the available space for the infrastructure. Classical economic analysis techniques are often unable to take into account some of the non-monetary parameters which have a huge impact on the final result of the choice, since they often include social acceptance and sustainability aspects. The application of Multi-Criteria Decision Analysis (MCDA) techniques can aid decision makers in the selection process, with the possibility to compare non-homogeneous criteria, both qualitative and quantitative, and allowing the generation of an objective ranking of the different alternatives. The coupling of MCDA and Geographic Information System (GIS) environments also permits an easier and faster analysis of spatial parameters, and a clearer representation of indicator comparisons. Based on these assumptions, a LRT and BRT system will be analysed according to their own transportation, economic, social and environmental impacts as a hypothetical exercise; moreover, through the use of MCDA techniques a global score for both systems will be determined, in order to allow for a fully comprehensive comparison.

From the 1832 Horse Pulled Tramway to 21Th Century Light Rail Transit/Light Metro Rail - a Short History of the Evolution in Pictures
From the 1832 Horse pulled Tramway to 21th Century Light Rail Transit/Light Metro Rail - a short History of the Evolution in Pictures By Dr. F.A. Wingler, September 2019 Animation of Light Rail Transit/ Light Metro Rail INTRODUCTION: Light Rail Transit (LRT) or Light Metro Rail (LMR) Systems operates with Light Rail Vehicles (LRV). Those Light Rail Vehicles run in urban region on Streets on reserved or unreserved rail tracks as City Trams, elevated as Right-of-Way Trams or Underground as Metros, and they can run also suburban and interurban on dedicated or reserved rail tracks or on main railway lines as Commuter Rail. The invest costs for LRT/LMR are less than for Metro Rail, the diversity is higher and the adjustment to local conditions and environment is less complicated. Whereas Metro Rail serves only certain corridors, LRT/LRM can be installed with dense and branched networks to serve wider areas. 1 In India the new buzzword for LRT/LMR is “METROLIGHT” or “METROLITE”. The Indian Central Government proposes to run light urban metro rail ‘Metrolight’ or Metrolite” for smaller towns of various states. These transits will operate in places, where the density of people is not so high and a lower ridership is expected. The Light Rail Vehicles will have three coaches, and the speed will be not much more than 25 kmph. The Metrolight will run along the ground as well as above on elevated structures. Metrolight will also work as a metro feeder system. Its cost is less compared to the metro rail installations. -
Trolleybuses: Applicability of UN Regulation No
Submitted by the expert from OICA Informal document GRSG-110-08-Rev.1 (110th GRSG, 26-29 April 2016, agenda item 2(a)) Trolleybuses: Applicability of UN Regulation No. 100 (Electric Power Train Vehicle) vs. UN Regulation No. 107 Annex 12 (Construction of M2/M3 Vehicles) for Electrical Safety 1. At 110th session of GRSG Belgium proposes to amend UN R107 annex 12 by deleting the requirements for trolleybuses (see GRSG/2016/05) and transfer the requirements into UN R100 (see GRSP/2016/07), which will be on the agenda of upcoming GRSP session in May 2016. 2. Due to the design of a trolleybus and stated in UN Regulation No. 107, trolleybuses are dual- mode vehicles. They can operate either: (a) in trolley mode, when connected to the overhead contact line (OCL), or (b) in bus mode when not connected to the OCL. When not connected to the OCL, they can also be (c) in charging mode, where they are stationary and plugged into the power grid for battery charging. 3. The basic principles of the design of the electric powertrain of the trolleybus and the connection to the OCL is based on international standards developed for trams and trains and is implemented and well accepted in the market worldwide. 4. Due to the fact that the trolleybus is used on public roads the trolleybus has to fulfil the regulations under the umbrella of the UNECE regulatory framework due to the existing national regulations (e.g. European frame work directive). 5. Therefore the annex 12 in UN R107 was amended to align the additional safety prescriptions for trolleybuses with the corresponding electrical standards. -
Santa Monica Smiley Sand Tram
Santa Monica Smiley Sand Tram TRANSFORMING BEACH PARKING, TRANSPORTATION AND ACCESS Prepared by Santa Monica Pier Restoration Corporation, February 2006 Concept History In the fall of 2004 a long-term event was staged in the 1550 parking lot occupying over 70% of the lot. The event producer was required to implement shuttle service from the south beach parking lots up to the Pier. A local business man offered the use of an open air propane powered tram and on October 5, 2004 at 8pm, the tram was dropped off in the 2030 Barnard Way parking lot for an initial trial run. The tram was an instant hit. Tram use in Santa Monica is not a new concept. A Santa Monica ordinance adopted in 1971 allows for the operation of trams along Ocean Front Walk and electric trams were operated between Santa Monica and Venice throughout the 1920’s. Electric trams took passengers between the Venice and Santa Monica Piers. - 1920 In 2004, due to pedestrian traffic concerns, Ocean Front Walk was not utilized for the tram. Instead, the official route for the tram was established along the streets running one block east of the beach. This route required extensive traffic management and, while providing effective transportation, provided limited access to the world-class beach. At a late-night brainstorming session on how to improve the route SMPD Sergeant Greg Smiley suggested that the tram run on the sand. With the emerging vision of the “Beach Tram”, the Santa Monica Pier Restoration Corporation began the process of research, prototype design and consideration of the issues this concept would raise. -
The Urban Rail Development Handbook
DEVELOPMENT THE “ The Urban Rail Development Handbook offers both planners and political decision makers a comprehensive view of one of the largest, if not the largest, investment a city can undertake: an urban rail system. The handbook properly recognizes that urban rail is only one part of a hierarchically integrated transport system, and it provides practical guidance on how urban rail projects can be implemented and operated RAIL URBAN THE URBAN RAIL in a multimodal way that maximizes benefits far beyond mobility. The handbook is a must-read for any person involved in the planning and decision making for an urban rail line.” —Arturo Ardila-Gómez, Global Lead, Urban Mobility and Lead Transport Economist, World Bank DEVELOPMENT “ The Urban Rail Development Handbook tackles the social and technical challenges of planning, designing, financing, procuring, constructing, and operating rail projects in urban areas. It is a great complement HANDBOOK to more technical publications on rail technology, infrastructure, and project delivery. This handbook provides practical advice for delivering urban megaprojects, taking account of their social, institutional, and economic context.” —Martha Lawrence, Lead, Railway Community of Practice and Senior Railway Specialist, World Bank HANDBOOK “ Among the many options a city can consider to improve access to opportunities and mobility, urban rail stands out by its potential impact, as well as its high cost. Getting it right is a complex and multifaceted challenge that this handbook addresses beautifully through an in-depth and practical sharing of hard lessons learned in planning, implementing, and operating such urban rail lines, while ensuring their transformational role for urban development.” —Gerald Ollivier, Lead, Transit-Oriented Development Community of Practice, World Bank “ Public transport, as the backbone of mobility in cities, supports more inclusive communities, economic development, higher standards of living and health, and active lifestyles of inhabitants, while improving air quality and liveability. -

With car empty, land counterweight, then release the brake. Turn the brake drum or disc until balance is made. 2. Loosen the brake springs on the brake. Unbolt the brake and slide the brake as far as possible toward the machine (gear-box) housing, making sure the brake shoes are clear of the drum or disc. 3. Take all bolts out of the motor coupling and install two (2) 5/16" tram rods (approximately 7" long) into the motor coupling (180° apart). Put two (2) 90° Starrett Model #196 indicators on one (1) tramming rod with one against the face of the brake drum or disc, and the other on the O.D. of the brake drum or disc. See Fig. 1 for indicator positioning. 4. Turn the tram rods horizontally with the drum or disc until a "0" reading is obtained. Swing the tram rods, turning with the indicator, 180° on the brake drum or disc. 5. While taking readings of the indicators, you should tap the motor (depending on reading) as you swing 180°. They should both read "0" on the drum or disc. 6. This would indicate that the motor is straight in line with the brake drum or disc, and swinging the indicators to an upright position on top of the drum or disc, you would need to again take a reading. The indicator on the face tells you whether the back of the motor is high or low, while the indicator on the O.D. -

Passenger Rail Primer
Passenger Rail Primer Thurston Passenger Rail Workgroup November 2005 Passenger Rail Characteristics This document is intended as a primer introducing and familiarizing the reader with the basic definitions of passenger rail and providing a comparison of common transit services in 2005. It was developed to facilitate a discussion of passenger rail and other transit options in the Thurston Region, in preparation of a regional rail plan. In the next section, Passenger Rail Overview, the fundamental characteristics of light rail, commuter rail and intercity rail are covered. Complementary and Alternative Transit Options (primarily common bus transit choices) provides a wider transit context within which the passenger rail modes coordinate and compete. After investigating transit options individually, they are compared and contrasted in a chart of their characteristics, Summarizing the Continuum of Services. Other Rail Transit Technologies provides a brief overview of less extensively used rail options and the Appendices provide additional details and information. Additional resources the reader may want to consult include: • The American Public Transportation Association (APTA) website at www.apta.com • The Victoria Transportation Policy Institute (VTPI) website at www.vtpi.org • Bureau of Transportation Statistics (BTS) website at www.bts.gov Passenger Rail Overview Introduction Passenger rail modes may be distinguished from one another based on a variety of characteristics – level of service, technology, right-of-way and operations. These characteristics are discussed in more detail in the other sections of this chapter. Like other transit services, however, in the most basic sense passenger rail modes break down by three distinct geographies – local, regional, and statewide or interstate. -

Horsecars: City Transit Before the Age of Electricity by John H
Horsecars: City Transit Before the Age of Electricity by John H. White, Jr. Horsecars were the earliest form of city rail transit. One or two horses propelled light, boxy tram cars over tracks buried in the streets. Only the tops of the iron rails could be seen; the rest of the track structure was below the surface of the pavement. The rails offered a smooth, low-friction surface so that a heavy load could be propelled with a minimal power source. The cars moved slowly at rarely more than six miles per hour. They were costly to operate and rarely ventured much beyond the city limits. There was no heat in the winter nor air-conditioning in the summer. Lighting was so dim that reading was impossible after sunset. Horsecars were in all ways low-tech and old wave, yet they worked and moved millions of passengers each day. They were indispensable to urban life. The public became enthralled with riding and would not walk unless the cars stopped running. Horsecars were a fixture in American city life between about 1860 and 1900. Even the smallest city had at least one horsecar line. Grand Street, New York, at Night, 1889. From Harper’s Weekly. Basic Statistics for U.S. Street Railways in 1881 Millions on the Move 415 street railways in operation 18,000 cars The earliest cities were designed for walking. Everything clustered around 100,000 horses 150,000 tons of hay consumed each year the town square. Churches, shops, taverns, schools were all next to one another. 11,000,000 bushels of grain consumed each year Apartments and homes were a few blocks away.
