Second Generation
Units 61 to 75 were delivered to Union Pacific beginning in 1954. These were visibly different from the previous generation because of the addition of external walkways on the sides of the locomotives, earning them the nickname "verandas" and making them hybrids of carbody and hood locomotives. The turbine and electrical equipment were essentially the same, though the side louver air intakes were replaced by the large roof mounted intake first tested on UP 53.
UP 61 was used in MU tests with diesels starting in 1958. These tests were successful and eventually all but six of the 4500 hp turbines were equipped to MU with diesels. As tonnage requirements increased, utilizing additional diesel locomotives for multiple unit operation became more commonplace.
The veranda ran about for 10 years before it is retired between August 1963 and April 1964.

Famous quotes containing the word generation:
“The women of my mother’s generation had, in the main, only one decision to make about their lives: who they would marry. From that, so much else followed: where they would live, in what sort of conditions, whether they would be happy or sad or, so often, a bit of both. There were roles and there were rules.”
—Anna Quindlen (20th century)
“I do not mean to imply that the good old days were perfect. But the institutions and structure—the web—of society needed reform, not demolition. To have cut the institutional and community strands without replacing them with new ones proved to be a form of abuse to one generation and to the next. For so many Americans, the tragedy was not in dreaming that life could be better; the tragedy was that the dreaming ended.”
—Richard Louv (20th century)
