PRR B1

The Pennsylvania Railroad's class B1 comprised 42 switcher-type electric locomotives built between 1926 and 1935. They were of 0-6-0 wheel arrangement in the Whyte notation with 700 horsepower. As built, the first 28 locomotives in the 1926 order formed semi-permanently coupled pairs grouped in three classes.

The first, class BB1, were AC powered and served as prototypes. The second, class BB2, were DC powered and served in the New York Terminal district, specifically between Sunnyside Yard and New York Penn Station. The third, class BB3, was AC powered and built for the Long Island Rail Road's electrified freight operation on the Bay Ridge Branch. In 1934 a follow-up order of 14 locomotives were built as single unit class B1 for the expanding main line AC electrification system. In addition to these new units all previous BB classes were split into single units and the BB2 class were re-powered for AC operation as that system replaced the old 650VDC system in the New York terminal. At this point all 42 units were re-classed as PRR B1.

Big Brother Canada (season 2)

Big Brother Canada 2 was the second season of the Canadian reality television series Big Brother. It was based upon the Dutch series of the same name, which gained notoriety in 1999 and 2000. The series was produced by Endemol USA and Insight Productions.

The season premiered on March 5, 2014 and ended after 71 days on May 8, 2014, where Jon Pardy was named the winner, and Sabrina Abbate, the runner-up.

Development

Following numerous seasons of Loft Story (2003–09) and a season of the French adaption of Big Brother (2010) it was confirmed that Shaw Media and Slice had picked up the format and would air the first English season in the country in 2013. The first season premiered in February 2013 to a positive critical and commercial reception. The show continued to have success, at one point becoming the most watched series on the channel.

The second season was officially confirmed on June 5, 2013. On the success of the series, Barbara Williams with Shaw Media stated "Last season, our Canadian edition of Big Brother exceeded all expectations, bringing in record audiences and engaging fans in ways we’d never done before [...] With season two chock-full of opportunities for viewers at home to influence the house and never before seen show-altering twists, our new batch of HouseGuests and fans are in for a wildly exciting ride."

PRR 1737

The Pennsylvania Railroad's K4s class Pacific number 1737 was the prototype of the class of 4-6-2 steam locomotives that eventually would number 425 locomotives.

The Pennsylvania Railroad in 1914 needed a steam locomotive to haul the passenger trains that the smaller E class Atlantics (4-4-2) could not handle. The 1737 was the first K4s ever built for the PRR. In passenger service, the 1737 would handle passenger trains, like the railroads flagship passenger train, the Broadway Limited. As the 1930s began, the 1737 and the other K4s locomotives would have to double-head passenger trains. This is because the Pennsylvania Railroad had increased passenger service time tables. The K4s Pacifics were unable to keep up with the work. The "Standard Railroad Of The World" made a few attempts to replace the 1737 and its sisters. They were the classes: K5, S1, and the T1. None of the replacements were very successful in railroad service. With these being a failure, the K4s had to continue hauling passenger trains until the Pennsylvania Railroad replaced steam locomotives with the increasingly popular and less costly diesel-electric locomotives in 1957.

Philippine Nuclear Research Institute

The Philippine Nuclear Research Institute is a government body in the Philippines, charged with overseeing the peaceful uses of nuclear technology.

Its main facility was a nuclear research reactor, PRR-1, first commissioned in 1963 as a TRIGA reactor and subsequently modified. As of 2007 it is non-operational since its shut down in 1988.

PRR 460

PRR 460, nicknamed the "Lindbergh Engine", is a Pennsylvania Railroad E6s steam locomotive now located in the Railroad Museum of Pennsylvania, outside of Strasburg, Pennsylvania in the United States. It was built in 1914 and became famous after racing an aircraft to New York City carrying newsreels of Charles Lindbergh's return to the United States after his transatlantic flight in 1927. In the late 1930s, No. 460 was operated by the Long Island Rail Road, and the Pennsylvania–Reading Seashore Lines in the early 1950s, before being retired in 1953. No. 460 is the only surviving locomotive of its class and was listed on the U.S. National Register of Historic Places in 1979. Since mid-2010, 460 has been undergoing restoration at the Railroad Museum of Pennsylvania.

Background

An experimental Model E6 was developed in 1910 and, after two other "sample" locomotives and four years of tests, it was found that the 4-4-2 Atlantic's speed equaled that of the larger 4-6-2 Pacific's. An additional 80 E6 locomotives were ordered with superheaters and classified as the E6s.
