Historical Uses
iRMX III operating system on Intel Multibus hardware is used in the majority core systems on CLSCS the London Underground Central Line signals control system was supplied by Westinghouse now Invensys and commissioned in the late 1990s. The Central Line is an automatic train operation line. Automatic train protection is by trackside and train borne equipment that does not use iRMX. It is the automatic train supervision elements that use a mix of iRMX on Multibus, and Sun Solaris operating system on Sparc computers. 16 iRMX local site computers are distributed along the Central Line together with 6 central iRMX computers at the control centre. All 22 iRMX computers are dual redundant. iRMX CLSCS continues in full operation in 2011.
Oslo Metro or Oslo Tunnelbane uses a similar although less complex Westinghouse supplied iRMX control system through the central Common Tunnel or Fellestunnelen tracks but was expected to be decommissioned in 2011.

Famous quotes containing the word historical:
“Some of us still get all weepy when we think about the Gaia Hypothesis, the idea that earth is a big furry goddess-creature who resembles everybody’s mom in that she knows what’s best for us. But if you look at the historical record—Krakatoa, Mt. Vesuvius, Hurricane Charley, poison ivy, and so forth down the ages—you have to ask yourself: Whose side is she on, anyway?”
—Barbara Ehrenreich (b. 1941)
“What are your historical Facts; still more your biographical? Wilt thou know a Man ... by stringing-together beadrolls of what thou namest Facts?”
—Thomas Carlyle (1795–1881)
