Hype for the Future 134A: City of Edmonton, Kentucky
Overview The City of Edmonton is located within the central portion of the Commonwealth of Kentucky in Metcalfe County, serving as the county seat and bypassed by the Louie B. Nunn Cumberland Expressway. Travel to the community is largely via United States Route 68 and Kentucky Routes 80, 163, 496, and 533. The surrounding area is also accessible via Routes 1243 to the northwest, 543 to the north, 544 to the northeast, 869 toward the Sulphur Well Historic District, 745 southeast of 68 to the […]https://novatopflex.wordpress.com/2026/03/14/hype-for-the-future-134a-city-of-edmonton-kentucky/

Island platform waiting room and canopies are under construction…

Time to get the fiddly canopies into the station buildings. And they are fiddly. Lot of measuring.

This lunchtime I’ve spent some time working on incorporating hanging lights into the Metcalfe platform canopies. It’s going quite well so far. Taken my time to work out exactly how to get the lamps where I want.

Platform 1 and the associated buildings contribute to make slow but steady progress…

Today the LED lights for lighting up the inside of the buildings on my model railway were delivered, meaning I can finally start building some of them! First up is the main station - a ticket office and a parcel depot (Metcalfe kits) on a 1500mm long platform.
Pics to follow.

#ACM named #Robert #Metcalfe recipient of the 2022 ACM A.M. #Turing #Award for leading the invention, standardization, and commercialization of #Ethernet local-area networking technology.
Metcalfe is Emeritus Professor of Electrical and Computer Engineering (ECE) at The University of Texas at Austin.
In 1973, while a Research Scientist at the Xerox Palo Alto Research Center ( #PARC ), Metcalfe circulated a now-famous memo on May 22, 1973 describing a "broadcast communication network" for connecting some of the first personal computers, #Altos, within a single building.
The first Ethernet ran at 2.94 megabit per second, which was ~10,000 times faster than the terminal networks it replaced starting in 1973.
Although the original design proposed implementing this network over #coaxial #cable, the memo envisioned "communication over an #ether" making the design adaptable to any future innovation in media technology including legacy telephone twisted pair, optical fiber, radio, and even power networks, to replace the coaxial cable as the "ether". That memo laid the groundwork for what we now know today as Ethernet.
The Ethernet architecture was developed to address Xerox's need to connect 100 of the new Alto personal computers and their new laser printers. The original architecture was based on a single wire bus with a single transceiver per node, thus enabling a cost-effective design.
The media access control in the Ethernet design incorporated Metcalfe's insights from his experience with Norm Abramson's RIP #ALOHAnet.
Metcalfe recruited David Boggs RIP to help build a 100-node Ethernet in two years. That first Ethernet was then replicated within Xerox to proliferate a corporate internet.
Metcalfe and Boggs' classic 1976 CACM article, "Ethernet: Distributed Packet Switching for Local Computer Networks," described the design of Ethernet. Metcalfe then led a team that developed the 10Mbps Ethernet, deployed internally at Xerox and forming the basis of subsequent standards.
