2-8-4 lines. The JNR rebuilt a total of 104 locomotives to the 2-8-4 wheel arrangement from its older 2-8-2 Mikado classes, the Class D50, Class D51 and Class D52. Some of these locomotives survived in service up to the end of steam traction on the JNR in 1974. In 1951, Mexico’s "Ferrocarriles Nacionales de México" (N de M) bought five 2-8-4 locomotives, built by Baldwin Locomotive Works in 1940, from Norfolk Southern Railway in the United States of America (USA), where they had become redundant due to dieselisation.

1/2 + 1/4 + 1/8 + 1/16 + ⋯ meters, and so on Zeno argued that the tortoise would always remain ahead of Achilles. The parts of the Eye of Horus were once thought to represent the first six summands of the series. 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
