While Wheaton has the longest escalators in the Western Hemisphere, WMATAâs longest are only in 7th place worldwide. The Moscow Metro station at Park Pobedy has the longest in the world, at 413 feet. Stations in St. Petersburg, Kiev, and Prague also have longer escalators than at Wheaton.
The IBM Selectric was introduced in 1961 (just like me!), and was revolutionary, in that the platen does not move, but instead the type element moves. The single type element (ball) has 88 characters on it, in 4 rows. This typewriter is a model 72, with a cloth ribbon in a plastic cartridge. It is a narrow platen model, they were available in 3 widths that I know of.
