METRO RAIL DESIGN CRITERIA SECTION 10 OPERATIONS METRO RAIL DESIGN CRITERIA SECTION 10 / OPERATIONS TABLE OF CONTENTS 10.1 INTRODUCTION 1 10.2 DEFINITIONS 1 10.3 OPERATIONS AND MAINTENANCE PLAN 5 Metro Baseline 10- i Re-baseline: 06/15/10 METRO RAIL DESIGN CRITERIA SECTION 10 / OPERATIONS OPERATIONS 10.1 INTRODUCTION Transit Operations include such activities as scheduling, crew rostering, running and supervision of revenue trains and vehicles, fare collection, system security and system maintenance. This section describes the basic system wide operating and maintenance philosophies and methodologies set forth for the Metro Rail Projects, which shall be used by designer in preparation of an Operations and Maintenance Plan. An initial Operations and Maintenance Plan (OMP) is developed during the environmental phase and is based on ridership forecasts produced during this early planning phase of a project. From this initial Operations and Maintenance plan, headways are established that are to be evaluated by a rail operations simulation upon which design and operating headways can be established to confirm operational goals for light and heavy rail systems. The Operations and Maintenance Plan shall be developed in order to design effective, efficient and responsive transit system. The operations criteria and requirements established herein represent Metro’s Rail Operating Requirements / Criteria applicable to all rail projects and form the basis for the project-specific operational design decisions. They shall be utilized by designer during preparation of Operations and Maintenance Plan. Any proposed deviation to Design Criteria cited herein shall be approved by Metro, as represented by the Change Control Board, consisting of management responsible for project construction, engineering and management, as well as daily rail operations, planning, systems and vehicle maintenance with appropriate technical expertise and understanding. -

ABSTRACT Grain shipping involves many sources of risk and uncertainty. In response to these dynamic challenges faced by shippers, railroad carriers offer various types of forward contracting and allocation instruments. An important feature of the U.S. grain marketing system is that there are now a number of pricing and allocation mechanisms used by most rail carriers. These have evolved since the late 1980’s and have had important changes in their features over time. The operations and impact of these mechanisms are not well understood, yet are frequently the subject of public criticism and studies and at the same time are revered by (some) market participants. -

Headway Adherence. Detection and Reduction of the Bus Bunching Effect
HEADWAY ADHERENCE. DETECTION AND REDUCTION OF THE BUS BUNCHING EFFECT Josep Mension Camps Director Central Services and Deputy Chief Officer of Bus Network. Transports Metropolitans de Barcelona (TMB). Miquel Estrada Romeu Associate Professor. Universitat Politècnica de Catalunya- BarcelonaTECH. 1. INTRODUCTION Transit systems should provide a good performance to compete against the wide usage of cars in metropolitan areas. The level of service of these systems relies on a proper temporal and spatial coverage provision (high frequencies, low stop spacings) as well as significant regularity and comfort. In this way, bus systems in densely populated cities usually operate at short headways (10 minutes or less). However, in these busy routes, any delay suffered by a single bus is propagated to the whole bus fleet. This fact causes vehicle bunching and unstable time-headways. In real bus lines, we usually see that two or more vehicles arrive together or in close succession, followed by a long gap between them. There are many sources of potential external disruptions in the service of one bus: illegal parking in the bus lane, failure in the doors opening system, traffic jams, etc. However, some intrinsic characteristics of transit systems and traffic management may also induce delays at specific vehicles such as traffic signal coordination and irregular passenger arrivals at stops. These facts make the bus motion unstable. Therefore, bus bunching is a common problem in the real operation of buses all over the world that must be addressed. The crucial issue is that bus bunching has a great impact on both users and agency cost. From a passenger perspective, the bus bunching phenomena increases the travel time of passengers (riding and waiting time) and worsens the vehicle occupancy. -

The limitations of size, the power required, and the stability of these high-speed boats are discussed. 6nrr I- I I_, I I __I 311~ba~ 0 'THE HYDROFOIL BOAT Although work has been going forward on the development of the hydrofoil boat for more than fifty years and although a number of such boats of the most diverse types and sizes have been constructed, the general public is not very familiar with this type of high-speed craft. However, the state of research and technology as well as the test results obtained with hydrofoil boats built thus far have enabled us for years to utilize hydrofoil boats which are of considerable size and are safe to operate in ship traffic. The technical and economic inter- est presently being shown in these boats justifies the assumption that the hydrofoil boat will soon develop into a familiar means of transportation in high-speed ship traffic. -
Making Headway, Capital Investments to Keep Transit Moving
CAPITAL INVESTMENT PLAN Making Headway Capital Investments to Keep Transit Moving 2019–2033 headway (/ˈhed wā/) noun 1. forward movement or progress, especially when the way is difficult. 2. the average interval between trains, streetcars, or buses. The shorter the headway, the more passengers carried per hour. Making Headway — Capital Investments to Keep Transit Moving January 2019 From the Chief Executive Officer In January 2018, the TTC published a new Corporate Plan that clearly laid out our priorities for the next five years. At the top of the list was transforming for financial sustainability. “Fiscal sustainability,” we said, “depends on our ability to fund what the TTC is being asked to deliver over the long term.” We committed to providing better budget information for improved long-term decision-making. Over the past 12 months, we have undertaken a massive, multi-department review of all of our assets. The result is this Capital Investment Plan. Toronto’s transit system is hailed as among the most multi- modal systems in the world, with seamless integration between buses, streetcars, Wheel-Trans and the subway. The TTC’s interdependent network of fleet, track, power, maintenance and other infrastructure moves more than half a billion people annually. Funding for critical maintenance and system improvements is necessary. Projects that have been approved are still awaiting funding. Line 2 Capacity Enhancement is unfunded. Buses past 2021 are unfunded. The expansion of Bloor-Yonge Station, which is needed to accommodate ridership growth even before planned transit expansion, is unfunded. The TTC Way, which was introduced in our Corporate Plan, establishes clear guidelines for how we at the TTC work with each other, with customers and with our partners, including our funding partners. -

Grain and Soybean Industry Dynamics and Rail Service
Grain and Soybean Industry Dynamics and Rail Service Analytical Models of Rail Service Operations Final Report Michael Hyland, Hani Mahmassani, Lama Bou Mjahed, and Breton Johnson Northwestern University Transportation Center (NUTC) Parr Rosson Texas A&M University 1 Executive Summary To remain globally competitive, the United States’ grain industry and associated transportation services underwent significant restructuring over the past fifteen years. New technologies, helped by weather changes, led to sustained yield volume increases in the Upper Midwest. To move larger volumes faster and at lower cost, the railroad industry introduced shuttle train service. Traveling as a unit to the same destination, shuttle trains save considerable time in transit and potential delay, bypassing intermediate classification yards. Grain shippers concurrently began consolidating and storing grain in larger, more efficient terminal elevators (shuttle loaders) instead of country elevators. This report examines the effectiveness of shuttle train service and the terminal elevators supporting the shuttle train system, under different demand levels, through the formulation of simple mathematical models. In order to compare shuttle and conventional rail service, this paper introduces three distinct models. The first model, referred to as the ‘time model’, determines the time it takes to transport grain from the farm to a destination (e.g. an export elevator). The second model, referred to as the ‘engineering cost model’, determines the aggregate variable costs of transporting grain from the farm to an export elevator. The third model, referred to as the ‘capacity model’, determines the maximum attainable capacity (i.e. throughput) of a rail network as a function of demand for rail transport and the percentage of railcars on the network being moved via shuttle service and conventional service. -
