Previously he was employed by the Southern Railway System, the Electro-Motive Division of General Motors and the Chicago & North Western Transportation Company. He has a bachelor's degree in mechanical engineering from the Milwaukee School of Engineering and a Master of Management degree from Northwestern University which he attended on a General Motors Fellowship. Iden is a registered professional engineer in several states, and a federally licensed locomotive engineer. His recent work at Union Pacific includes leading the team which developed the world's first multi-engine ultra-low emitting diesel "Genset" switching locomotive. Iden has also lead UP's experimental efforts with retrofitting the first American switcher with diesel particulate filters, and retrofitting the first older line-haul locomotive with an oxidation catalyst.
