Question: Who was the founder of the railroad? Passage:The original train track through Irwindale were built by the Los Angeles and San Gabriel Valley Railroad. The Gold line uses the old right of way of the Los Angeles and San Gabriel Valley Railroad who built the first train tracks through Irwindale in 1887. The Los Angeles and San Gabriel Valley Railroad was founded in 1883, by James F. Crank with the goal of bringing a rail line to San Gabriel Valley from downtown Los Angeles. Los Angeles and San Gabriel Valley Railroad was sold on May 20, 1887 into the California Central Railway. In 1889 the rail line was consolidated into Southern California Railway Company. On Jan. 17, 1906 Southern California Railway was sold to the Atchison, Topeka and Santa Fe Railway and called the Pasadena Subdivision. Amtrak-Santa Fe ran the Southwest Chief and Desert Wind over this line through Irwindale, but relocated the Desert Wind to the Fullerton Line in 1986. The Santa Fe line served the San Gabriel Valley until 1994, when the 1994 Northridge earthquake weakened the bridge in Arcadia and the track was closed till the Gold line was built. The rail line crosses the San Gabriel River on a long girder bridge, then passes through the Santa Fe Dam Recreation Area (how it received its name). The rail line intersected the north end of the former SP Azusa Industrial Track at Irwindale (MP 118.2). Irwindale had a 6,165 foot rail siding that passed the Miller Brewing Company's Irwindale brewery. From there the tracks continued and crossed beneath Irwindale Avenue.

Question: What year was the single that once held the title of best-selling digital song of all time release? Passage:Described by will.i.am as "party album[s]", The Black Eyed Peas released the electronic dance-influenced The E.N.D. and The Beginning in 2009 and 2010, following the 2008 election of Barack Obama as President of the United States. The band welcomed Obama's election; will.i.am had recorded and released "Yes We Can", a single that promoted Obama's election campaign during the Democratic Party primaries, and often claims the song had helped Obama get elected. The band's most commercially successful single during this period, "I Gotta Feeling", was inspired by the band's perception of being "in the center of a ginormous change in America". The track became the best-selling digital song of all time until it was surpassed by Pharrell Williams' "Happy" in 2014. By the end of 2010, The E.N.D. had sold over eleven million copies worldwide, while The Beginning had sold over two million copies worldwide. The band had intended to return to the studio to create their seventh studio album soon after the release of The Beginning, though frequent delays and Taboo's diagnosis with testicular cancer in 2014, along with his subsequent treatment and recovery, led to the project being put on hiatus.

Question: How many people lived in Maldon the year Strutt served at the siege of Gibraltar? Passage:Strutt was baptised at Springfield, Essex, on 26 February 1762, the second son of John Strutt, of Terling Place, Essex, by Anne, daughter of the Rev. William Goodday of Maldon. Entering the army in 1778, he joined his regiment, the 61st, at Minorca. Later he was appointed to a company in the 91st, and took part in the defence of St. Lucia. In 1782, having exchanged into the 97th, he served at the siege of Gibraltar. On the signing of the preliminaries of peace he purchased a majority in the 60th regiment, and, being placed on half-pay, visited several German courts. In 1787 he was sent with his regiment to the West Indies, where he took an active part in military affairs. Succeeding to a lieutenant-colonelcy by special command of George III, he was removed to the 54th, and went with the army of Lord Moira to Flanders. In 1794 he bore a very distinguished part against the French at Tiel, going through much hard fighting. On his return he was sent to St. Vincent, where he was raised to the rank of brigadier-general. In January 1796, with two hundred men, he attacked a force of twelve hundred, being himself thrice wounded, and losing his right leg. On his return to England he was received with marked favour by the king, and on 23 February 1796 was made deputy governor of Stirling Castle, afterwards serving upon the staff in Ireland. On 23 June 1798 he was raised to the rank of major-general, and on 13 May 1800 he was, as a reward for his services, appointed to the sinecure office of governor of Quebec, and he held that post until his death. He died at Tofts, Little Baddow, Essex, on 5 February 1848, having seen an exceptional amount of military service, both at home and abroad.
