Train Modern Technology

Metro authorities have positioned an indefinite keep on going back to computer-motivated trains, a choice which comes greater than two years right after the firm vowed to bring back the technique of computerized procedures. The alteration in programs, initial noted by WAMU, is a component of carried on worries in regards to the modern technology that had been placed on hold from the wake of the fatal 2009 Red Line train collision in close proximity to Fort Totten.

The technological innovation, referred to as automated workout operation (ATO), employs application to ascertain the motion of trains during the entire method and manage when, and the way rapidly, the trains accelerate and slow-moving to some end. The technologies is useful because it possesses a better ride for travellers and will help stop teach bunching that can lead to delays. But ATO is also a safety device targeted at decreasing the opportunities for man problem on the rails. The matter of workout operator inattentiveness has become more popular in recent years, as the government has noted many incidents by which operators have work red-light-weight signs around the songs, in some cases endangering passengers or colleagues. Lately, Metro has put in $106 million to setup 1,730 new path circuits during the entire system – a project that was required with the Federal Transportation Basic safety Table, and has also been done in part to get ready for your ultimate come back to computerized functions.

Metro lightly reintroduced ATO in the Reddish colored Line two years earlier, letting 8-automobile trains to be work in automatic method during the early morning and night time hurry time. Previous general director Richard Sarles possessed called that advancement “a milestone fulfillment,” and vowed to come back all of the subway lines to ATO by this year. Now, Metro representatives say they are certainly not prepared to forever reintroduce the technologies because they believe it is more essential to target fixing monitor flaws and updating the ability method. They also are also anxious that reviving the technological innovation now could jeopardize the protection of track staff and inspectors at one time when the company is performing much more monitor reconstruction job while in normal hours of operation.

“There are just other priorities at this time (e.g. SafeTrack),” Metro spokesman Dan Stessel explained. “And not a single dollar in the $106 million was lost, because the monitor circuit modules must be replaced regardless of whether functioning in manual or automatic.” Stessel said Metro will not be automatically abandoning the automatic technologies, which had been deemed a best attribute of your method whenever it debuted in 1976. The agency is planning to retain the services of a professional impulses advisor to ascertain no matter if ATO continues to be advisable for Metro – so when, and how, to bring it again on the web. “If the professional signs advisor decides that going back to ATO might be safely and effectively integrated, [Metro] control will likely determine another steps,” Stessel mentioned.

Modern TechnologyATO is a kind of attribute at transit methods around the world. But automatic functions were actually halted from the Washington place in 2009, whenever a glitch in Metro’s ATO structure was found to responsible for the Fort Totten accident. In that event, the computer modern technology did not identify a Red-colored Line train that had been halted in the keeps track of. Another train, running on automobile-initial, slammed into the back of the initial coach at practically 50 mph. nine individuals was killed.…


We are so used to computers being present in all areas of life that we tend to take them for granted. This is especially true of the generation that has grown up with desktop and laptop technology. However, the history of computers goes back many decades and the computers that we see today are much more evolved and advanced than the computers of even a decade ago. There are five differentiable generations of computers and each of them can be defined by major technological development that changed the way the computers operated. This in turn has led to less expensive, more compact, efficient, more powerful and robust computers.

1940-1956 – First generation – vacuum tubes

The circuitry in these first generation computers consisted of vacuum tubes and magnetic drums were used for memory. They were huge in size and literally took up the space of a large room. Running them also cost a fortune. The materials used in these computers were inefficient and they generated too much heat, used up large amounts of electricity which consistently caused breakdowns.

This generation of computers made use of machine language which is the most basic programming language. They could solve only one problem at a time.

1956-1963 – second generation – Transistors

Transistors took the place of vacuum tubes in the computers of the second generation. Transistors were invented in the year 1947, but they were not used much in computers till the end of the 1950s. They were a major improvement over vacuum tubes, but they still generated heat enough to damage the computers. However, due to the transistors, computers became smaller, faster, cheaper and consumed lesser electricity. The language in these computers evolved from cryptic binary to symbolic and this allowed the programmers to make the instructions in words.

1964-1971 – Third generation – Integrated circuits

Transistors started being miniaturized and were placed on silicon chips known as semiconductors. This caused a major increase in speed and efficiency of the computers. In these computers for the first time keyboards and monitors were used which interfaced with an operating system. As a result these computers could run many applications at the same time with the help of a central program which functioned to monitor memory. As a result of this evolution in technology, the computers became cheaper and for the first time they were placed in the mass market in the 1960s.

1972-2010 – Fourth generation – microprocessors

This is the revolution led by Intel who developed the Intel 4004 chip in the year 1971. Due to this advancement in technology it became possible to place all the components of the computer on a single chip. As a result the computers which once occupied an entire room could be placed in the palm of the hand. In the year 1981 the first computer designed for use in the home and in 1984 the Macintosh was introduced by Apple.

2010 – Fifth generation – artificial intelligence

These devices are still being developed but some technologies like voice recognition. Artificial Intelligence is actually made possible with the help of parallel processing and superconductors

The computer is still evolving continuously and there is a lot more to be discovered
