Passage: After leaving Union Station and crossing the Los Angeles River, the line follows the San Bernardino Freeway and El Monte Busway until just after the Cal State L.A. station; it then runs in the median of the San Bernardino Freeway to the El Monte Station along the former route of the Pacific Electric Railway's San Bernardino Line. Starting at El Monte, the line parallels the Union Pacific's Sunset Route (ex-Southern Pacific) for a few miles before turning northeast at Bassett onto a Southern Pacific branch. At (a former Southern Pacific/Pacific Electric-Santa Fe crossing), it switches to the Santa Fe; from Claremont to just west of San Bernardino it follows what was the Santa Fe's Pasadena Subdivision (and before that the Second District of the LA Division, the Santa Fe passenger main line). The San Bernardino Line is mostly single track with 6 passing sidings and short sections of double track near Covina, between Pomona and Montclair, and west of Fontana.

question:
Passage: Yakov Hanecki was born in Warsaw, then in the Russian Empire, the son of Stanislav von Fürstenberg, a beer manufacturer of German descent, who had adopted Poland as his homeland. In 1896 he joined the Social Democracy of the Kingdom of Poland (SDKP - later the Social Democracy of the Kingdom of Poland and Lithuania (SDKPiL)) led by Rosa Luxemburg and her lover, Leo Jogiches. He moved to Germany in 1901 and studied in rapid succession at Berlin, Heidelberg, and Zurich universities. From 1902, he was a professional revolutionary, normally based in Cracow, under Austrian rule, organising the transport of illegal literature across the Russian border. In August 1903, as a member of the Main Administration of the SDKPiL, he was one of two Polish delegates to the Second Congress of the Russian Social Democratic Labour Party (RSDLP) in Brussels. The Congress later adjourned to London, under pressure from the Belgian police, and there the RSDLP split into its Bolshevik and Menshevik factions, but Hanecki and the other Polish delegate, Adolf Warski, did not make the journey to London, having failed to agree terms on which the RSDLP and SDKPiL could collaborate.

question:
Passage: Jarrett's career began in South Florida, where he was a successful stage and commercial actor and print model. His first feature film role was in the teen comedy "Summer Job", where he played an effete hairdresser. Next came minor roles in such films as The Bodyguard with Kevin Costner and Whitney Houston as well as Miami Vice and Unsolved Mysteries. Jarrett also hosted several nationally syndicated television shows, such as "Flight," "American Automotive," and "Better Farming" for SportsChannel America, as well as an exercise video with world championship boxer Alexis Arguello called "Boxercise." In 1992, Jarrett journeyed to Los Angeles and turned his attention to screenwriting. His original screenplay Laws of Deception was made into a film in 1997 and starred C. Thomas Howell, James Russo and Brian Austin Green and was directed by Joey Travolta, brother of John Travolta. Jarrett had a small role in this film as Mr. Farina, a corrupt businessman. Another original script entitled American Vampire was produced and starred Carmen Electra, Sydney Lassick, and Adam West. It was Carmen Electra's first feature. In 2003, Jarrett appeared as a contestant on the brainy television game show Jeopardy! as Rollin Jewett. In 2004, Jarrett was commissioned by Scott Reeves and Aaron Benward, the popular country music duo known as Blue County, to write a script in which they were to costar as brothers in a fictional place called Blue County. As the duo's music became more popular, the film was postponed and Benward and Reeves used the name for their band, which is still touring today. In 2017, his feature screenplay "Demons 4 Dummies" was a finalist in the Final Draft Big Break Screenwriting Contest.
