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:
Question: How many miles from Chattanooga, Tennessee does it take to travel to Lookout Mountain by railway? Passage:The Lookout Mountain Incline Railway is a inclined plane funicular railway leading to the top of Lookout Mountain from the historic St. Elmo neighborhood of Chattanooga, Tennessee. Passengers are transported from St. Elmo's Station at the base, to Point Park at the mountain summit, which overlooks the city and the Tennessee River. It is just a short drive to three of Chattanooga's main tourist attractions, Ruby Falls, Cavern Castle, and Rock City. The railway is approximately in length (single-track except for a short two-track passing loop at the midway point, allowing operation of two cars at one time). It has a maximum grade of 72.7%, making it one of the world's steepest passenger railways. It obtained Historic Mechanical Engineering Landmark status in 1991. The cable system for the cars was made by the Otis Elevator Company.

question:
Question: In which state did Fischell work full time in a lab for 25 years? Passage:Robert Fischell (born 1929) is a physicist, prolific inventor, and holder of more than 200 U.S. and foreign medical patents. His inventions have led to the creation of several biotechnology companies. He worked at the Johns Hopkins University Applied Physics Laboratory full-time for 25 years, and part-time for an additional 13 years. He contributed to APL's satellite navigation work, and later developed a rechargeable implantable pacemaker that could be programmed with radiowaves, (Pacesetter Systems purchased by Siemens, now the CRM division of St. Jude Medical). He and his team at Hopkins also helped miniaturize the implantable cardiac defibrillator. Mr. Fischell went on to invent the implantable insulin pump (MiniMed, spun off from Pacesetter Systems in 1985), numerous coronary stents used to open clogged arteries (IsoStent merged with Cordis, in turn purchased by Johnson & Johnson), and two extraordinary feedback systems that provide early warning of epileptic seizures (NeuroPace) and heart attacks (Angel Medical Systems). Fischell recently donated $30 million to the University of Maryland College Park Foundation to establish a bioengineering department and an institute for biomedical devices at the A. James Clark School of Engineering.
