COMMUTER RAIL TRANSPORTATION—The term commuter rail transportation has the meaning given the term commuter service in section 103(9) of the Rail Passenger Service Act (45 U.S.C. 502(9)). 

The GeoSRM is a new map-based tool for showing how risk is distributed across the rail network. To demonstrate the concept, the GeoSRM has been piloted on the Wessex route in England. The Wessex route operates a mix of services, whilst dominated by commuter services into London Waterloo station, but also longer distance services to Southampton, Bournemouth, Exeter and Portsmouth.

Service life is another important criterion when configuring a drive system. In commutator equipped machines (DC motors), the brushes are subject to abrasion. Service time here is on the order of 2,000 to 8,000 hours, with correct current load, correct contact pressure, and purity of the cooling air influence service time considerably. The commutator is also subject to wear and should be checked regularly and, when required, overhauled. 

External disasters can trigger internal disasters for an organization. A severe weather condition like a snowstorm or a geological event like an earthquake can create both conditions for a hospital. During severe weather events, staff may not be able to commute to work, but trauma cases may increase, and this results in a situation where there is short staffing with a simultaneous increase in demand for services. An earthquake may cause structural damage to the hospital, destroy roads and highways, and cause mass casualties in the community. Such a hospital would be faced with simultaneous internal and external disasters. 

At speeds of about 120 miles per hour and greater, there is significant wear on both wheels and rails. Federal Railroad Administration standards for conventional freight trains and commuter trains allow relatively large discrepancies between the level of one rail and another—1.25 inches for 80 mph operations. However, the FRA standard drops to 0.5 inches [sic] for 120 mph operations. By comparison, the French TGV standard is 0.16 for the 170 mph portions of the system. Satisfying the standards for high-speed service is not impossible, but it is very expensive.

C) the National Railroad Passenger Corporation, and any commuter authority (as defined in section 103(8) of the Rail Passenger Service Act). 

SERVICE AREA—The regulations issued under this section shall require the provision of paratransit and special transportation services required under this section in the service area of each public entity which operates a fixed route system, other than any portion of the service area in which the public entity solely provides commuter bus service. 

Commuter rail can be seen as a hybrid between subway systems and interurban train systems. Like subways, commuter rail systems serve the needs of a single city or metropolitan area. Commuter trains use a network of tracks that provide service between a... 

With its reputation as a small college for the nation s elite, Princeton seems an unlikely environment for a social movement led by engineers. While it may have appeared a bastion of conservatism compared to Berkeley or Columbia, structural changes at Princeton in the wake of World War II were dramatic. The university was transformed from a school dedicated primarily to the humanities to nationally a leader in science and engineering. The expansion in physics was especially notable as faculty commuted in the nation s service between suburban New Jersey, Los Alamos, and Oak Ridge. But Princeton s previously unexceptional School of Engineering also became an elite program. ... 

Often commuters encounter intersections which operate near capacity limits and do not know when they will experience unacceptable traffic conditions. There are days where they drive through such intersections without major disruption and days on which they do not accept adverse traffic conditions, which can be expressed by means of a variety of measures including delays, queues, stops etc. [Chodur 2004]. For each driver the ability to estimate the likelihood of favourable traffic conditions at the time of departure and select the best route is extremely important in terms of minimizing trip time. The aim of this paper is to show the application of elements of reliability theory to the description of the functioning of a lane with a left turn at a signalised intersection in Krakow over several successive working days in favourable weather conditions. The analysis will cover 24-hour periods and record moments in time in which there were adverse traffic conditions from the viewpoint of drivers. Lane s functioning is associated with the level and quality of service and is renewable in time. The concept of renewal in this case is directly related to theoretical renewal, when a renewed object reveals the same reliability as directly before the overload. 

The sentence was that he should hear mass in the cathedral at Lima, stripped naked, with a candle in his hand, and that he should be perpetually banished from the Indies. Until his departure he was to be kept in the Monastery of San Domingo at Lima, without any books, fasting on Wednesdays and Fridays, and reciting seven penitential psalms. Sarmiento appealed to the Pope, and obtained a commutation of the banishment, with license to reside at Cuzco and other parts of Peru until 15 7 It was years before he was free from annoyance and persecution, and it was due to the great value of his services that he was protected by the Government from the intolerable tyranny of the Inquisition. 

Mechanical Failure-Related Delays in Commuter Rail Service... 

Commuter rails are used in many North American cities. Many times, mechanical failure is the main cause for delays in commuter rail service. In fact, according to Nelson and O Neil [20], approximately one-tenth of all commuter rail service delay minutes relate to mechanical causes such as the following ...

Of course, even a low level of preventive effort by a railroad will not mean that an accident occurs during every trip. A regular commuter will go many years, or even decades, before they are involved in an accident. (In the event that the commuter suffers a fatal injury, this new information may come too late to affect their travel-demand behavior ) Nevertheless, accident probabilities may be inferred from more readily observable attributes of service such as operating practices, minor operating problems, the condition of equipment, on-time performance, and the demeanor of employees.
