The problem with trying to guarantee replacement parts for electronic components, is that your suppliers wont guarantee supply of their devices for an extended length of time. I recall once working on a project where one of the components that had been selected for the product was obsoleted during the development phase and the board had to be re-engineered with a newer component. You can usually expect to get guaranteed supply for 5-7 years out of a supplier, but more than that and you are stuck having to make alternative arrangements. You might stretch a repair stock to 10-12 years by buying in before an item becomes obsolete, but 30 years! tim |

NRN radios were 1980s technology. We made lots of them when I worked at Philips. By the end of the 1990s it wasn't even possible to manufacture the radios any more because electronics as discrete components on circuit boards were used any more. Replacement radio models hadn't been through the same approval process necessary for safety assurance of railway control systems. Yet radios manufactured back to the mid-80s are still today installed in train cabs and used at least until recently. A substantial cottage industry grew up finding and repairing such radios to keep the railway going. No doubt the same sort of thing will have to happen with the successor GSM-R technology. -- Colin Rosenstiel |

Well that is very interesting to read, I lived in Croydon when the original trams ran up the high street, often got my bike wheels stuck in the tramlines. I also worked for Philips at the height of the 60's consumer boom in the giant stores in Beddington Lane, valves, transistors, magnetic components and tons of other interesting stuff, we had the first colour tv's they came in by the lorryload, we had to unload and stack them, they weighed at least 45 to 50 pounds, then a couple of days later we had to hump them onto another lorry. We used to get overtime at xmas in the record stores in the Croydon factory in Purley Way The stores was about 6 acres of double floor dexion with lifts and stairs and about 2 acres of rows of standard green pallets with wooden pallets on board it was fun racing around on a fork lift truck, and our first electric pallitron was one of the wonders of the universe at the time Those were the days......... |
