This brooch marks the introduction of diesel locomotives to part of the Lehigh Valley Railroad in the USA. By the 1940s locomotives powered by diesel were beginning to replace steam locomotives. Diesel engines were both more efficient to run and easier to mass produce, and represented an exciting new technological advance. \r\n\r\nThe Lehigh Valley Railroad was constructed during the 19th century to transport Anthracite coal from Pennsylvania to the populous, industrial areas on America’s east coast. It earned the nickname ‘the route of the black diamond’, after its profitable cargo. A black diamond shape can be seen on the company's logo, as depicted on the front of this brooch.","physicalDescription":"Gold brooch in the form of a diesel locomotive, set with diamonds, sapphires and rock crystal.","artistMakerPerson":[{"name":{"text":"Unknown","id":"A1848"},"association":{"text":"","id":""},"note":""}],"artistMakerOrganisations":[],"artistMakerPeople":[],"materials":[{"text":"gold","id":"AAT11021"},{"text":"diamonds","id":"AAT11084"},{"text":"quartz crystal","id":"AAT11152"}],"techniques":[],"materialsAndTechniques":"Gold, diamonds, sapphires and rock crystal","categories":[{"text":"Jewellery","id":"THES48930"},{"text":"Metalwork","id":"THES48920"},{"text":"Accessories","id":"THES48998"}],"styles":[],"collectionCode":{"text":"MET","id":"THES48599"},"images":["2007BP3793","2007BP3794","2007BP3391","2007BP3390"],"imageResolution":"low","galleryLocations":[{"current":{"text":"91","id":"THES49703"},"free":"","case":"32","shelf":"D","box":"7"}],"partTypes":[[{"text":"brooch","id":""}]],"contentWarnings":[{"apprise":"","note":""}],"placesOfOrigin":[{"place":{"text":"USA","id":"x29333"},"association":{"text":"made","id":"x28654"},"note":""}],"productionDates":[{"date":{"text":"ca. 1948","earliest":"1943-01-01","latest":"1952-12-31"},"association":{"text":"made","id":"x28654"},"note":""}],"associatedObjects":[],"creditLine":"Given by the American Friends of the V&A through the generosity of Patricia V.
