Pacer (train)

Pacer is the operational name of the British Rail Classes 140, 141, 142, 143 and 144 diesel multiple unit railbuses, built between 1980 and 1987. Intended as a short-term solution to a shortage of rolling stock (with a lifespan of no more than 20 years), as of 2016 many Pacer railbuses are still in use.

The Rail Vehicle Accessibility Regulations require that all public passenger trains must be accessible to disabled people by 2020. No Pacers currently meet this requirement and will therefore need to be withdrawn by that date unless they receive an extensive refurbishment. Porterbrook, which owns the Class 143 and Class 144 fleets, has proposed such a refurbishment, while Angel Trains which owns the Class 142 fleet does not see such a refurbishment as a viable option. The Long Term Passenger Rolling Stock Strategy published in 2014 for the Rail Industry indicates no new DMUs will be ordered in the following 10 years, which means Pacers will need to be replaced by existing DMUs cascaded from newly electrified lines.

Project PACER

Project PACER, carried out at Los Alamos National Laboratory (LANL) in the mid-1970s, explored the possibility of a fusion power system that would involve exploding small hydrogen bombs (fusion bombs)—or, as stated in a later proposal, fission bombs—inside an underground cavity. As an energy source, the system is the only fusion power system that could be demonstrated to work using existing technology. However it would also require a large, continuous supply of nuclear bombs.

The earliest references to the use of nuclear explosions for power generation date to a meeting called by Edward Teller in 1957. Among the many topics covered, the group considered power generation by exploding 1 Mt bombs in a 1,000-foot (300 m) diameter steam-filled cavity dug in granite. This led to the realization that the fissile material from the fission sections of the bombs, the "primaries", would accumulate in the chamber. Even at this early stage, physicist John Nuckolls became interested in designs of very small bombs, and ones with no fission primary at all. This work would later lead to his development of the inertial fusion energy concept.

Train (album)

Train is the 1998 self-titled debut album from the band Train. The album was self-produced for $25,000 and three singles from the album were released. The first single released, "Free", was largely a hit on rock stations. The second, "Meet Virginia", peaked at No. 20 on the Billboard Hot 100, and the third single from the album was "I Am". The album has been certified Platinum by the RIAA.

Train (roller coaster)

A roller coaster train is a vehicle made up of two or more cars connected by specialized joints which transports passengers around a roller coaster's circuit.

It is called a train because the cars follow one another around the track, the same reason as for a railroad train. Individual cars vary in design and can carry from one to eight or more passengers each.

Many roller coasters operate more than one train, sometimes several, simultaneously. Typically they operate two trains at a time, with one train loading and unloading while the other train runs the course. On the Rock 'n' Roller Coaster at Walt Disney World, there are five trains, but only four operate at a time (the trains are rotated out on a regular basis for safety reasons).

Basic safety features

Roller coaster trains have wheels that run on the sides (side friction or guide wheels) and underneath the track (upstop, underfriction, or underlocking wheels) as well as on top of it (road or running wheels); these lock the train to the tracks and prevent it from jumping the track. The side wheels can be mounted on the outside or inside of the train, depending on the manufacturer (although outside-mounted wheels are more common). The wheels are sometimes located between the cars, as well as at the front and rear of the entire train.

Train (clothing)

In clothing, a train describes the long back portion of a skirt, overskirt, or dress that trails behind the wearer. It is a common part of a woman's court dress, formal evening gowns or wedding dress.

In the Roman Catholic Church the cappa magna (literally, "great cape"), a form of mantle, is a voluminous ecclesiastical vestment with a long train. Cardinals, bishops, and certain other honorary prelates are entitled to wear the cappa magna.
