Baldwin 4-8+8-4-750/8-DE was used for the one of a kind prototype #4500 Seaboard Air Line "Centipede". Baldwin 4-8+8-4-750/8-DE The Baldwin 4-8+8-4 750/8 DE1 was the Baldwin Locomotive Works' first attempt at road diesel locomotive. The trucks were configured in a 2-D+D-2 wheel arrangement. Only a single test unit was built. In 1943 Baldwin built an experimental "Centipede" as a demonstrator unit, which was assigned road #6000. The uniquely styled unit, with its upright, aggressive prow, was to be powered with eight model 408 V8 diesel engines (which would have produced ), though only four were actually installed. The locomotive's running gear design
1/2 + 1/4 + 1/8 + 1/16 + ⋯ 1/2 + 1/4 + 1/8 + 1/16 + ⋯ In mathematics, the infinite series is an elementary example of a geometric series that converges absolutely. There are many different expressions that can be shown to be equivalent to the problem, such as the form: 2 + 2 + 2 + ... The sum of this series can be denoted in summation notation as: As with any infinite series, the infinite sum is defined to mean the limit of the sum of the first terms as approaches infinity. Multiplying by 2 reveals a useful relationship: Subtracting from both sides, As approaches
