Input: Consider Input: 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.

Input: Consider Input: Question: How old was Hosaka when Kuroda made his PWC debut against him? Passage:Kuroda began his professional wrestling career in January 1993, when he was trained by Pro Wrestling Crusaders (PWC) at their dojo and made his debut on March 18, 1993 against Hideki Hosaka. PWC closed after a few months and Kuroda resumed his training at the Frontier Martial-Arts Wrestling (FMW) dojo. He made his FMW debut as a fan favorite with Masato Tanaka by losing to Dark Ranger and Masaru Toi in a tag team match on October 15. Kuroda remained in the low card for many years in the company and was usually utilized in opening matches on the card and served as a enhancement talent against higher level opponents, winning against only lesser known talent. He was often paired with fellow newcomer Tanaka in mid-card matches during the early years of his career and often wrestled Tanaka, Koji Nakagawa and Gosaku Goshogawara. Kuroda's first main event match took place on November 26, 1994, when he teamed with Atsushi Onita, Katsutoshi Niiyama and Masato Tanaka to defeat Mr. Pogo, The Gladiator, Hideki Hosaka and Hisakatsu Oya in a no ropes barbed wire street fight deathmatch. Kuroda would team with Onita, Niiyama and Tanaka in several street fights during late 1994 and early 1995. In the summer of 1995, Kuroda was entered into the Young Spirit Tournament, a round robin tournament consisting of rising rookies of the company. He would lose all of his matches in the tournament against W*ING Kanemura, Hideki Hosaka, Koji Nakagawa and Hido, while wrestling Masato Tanaka to a double knockout to gain one point in the tournament.
