Im trying to track down pictures of pre CWR bullhead" economical" facing points locks used in ireland upto the 90s. in particular for my model of claremorris set in late 70s early 80s. I have come across two types but have somewhat indistinct photos. I wonder if you might have any knowledge, one type in use, seems to use a "cam" directly of the FPL mechanism to drive the switch blades through avery short action. see http://flic.kr/p /gW9nv9 the other type. uses a extended arm leading from the E-FPL mechanism, running upto the switch blade tiebars. then a cam/crank arrangement is used this can be seen here claremorris-p.jpg could you shed any light on these in more detail, what railway company manufactured them, drawings, better photos, Im trying to do ...

Every time I give the web address for the Yahoo Group "mrrelectronics" the remainder of the message vanishes. I'll try the text again. Might be best to look up the group via the Yahoo directory. Rene, You might want to contact this group. Members use and write programs for device known as PIC/AXE micro controllers. Small and economical they might do what you want. 102 routes might require a fair bit of code but the experts should be able to give advice. Membership, and advice, is free. I guess it would help if you could send them a schematic and some kind of table of requirements. I would be interested in the circuitry you are presently using for your smaller layout. It might help me with something I am pondering. If you have something suitable for transmission could you please send me, off list, at rjhenry@ ...

... out-reach of The Hobby". What do these nimnuls think they are achieving? Once upon a time, there were a few oddballs who played with trains, enough of them to support a magazine, a national organization, a handful of manufacturers and a gross or so of local clubs. People played with their trains and were happy. Now, after over half a century of "growing The Hobby", of "becoming a force in The Hobby Industry", "The Hobby" has become a big enough economic target to attract scumbags whose only talent is to work the system to make a buck. So some clever fellow is out to get "trade mark protection" for marks he did not devise so that he can harvest wealth for his cleverness. The UP is out to get a piece of the action on sales of model trains if the maker uses any of their marks. "The Hobby" is growing itself to death. It is making itself increasingly attractive to economic parasites. We do not need to "grow The ...

... http://www.tescopoly.org is even more interesting). Now the crux of the argument is that it will be almost impossible to wean folk off cheap subsidised food- hence the enormous sales of '2 for a fiver' chickens and the associated animal cruelty. I have to say that 4mm modellers are of a similar outlook. 'Fed' on components produced by 'kitchen table' manufacturers, sold at a price which did/does not equate to a commercial rate, I do seriously doubt if they would be prepared to pay an economic cost for these items.

Kind regards Andrew posted: 25 Oct 2018 09:19 from: Hayfield Richard Many of those who build their own track use ready to run flexitrack, either for speed or as you have said economics.

... 2020 09:21 from: Paul Boyd Hi Rob Your first type with a single switch rail was used in some Welsh quarry railways, and the Corris railway used them here and there. In my head there's a photo of one being "switched"- a man lifting the free end and moving it across, but of course I can't find it now. There's also the type used on the Penhryn Quarry Railway, with a switched crossing. (The photo is a quick snap from an old book). Note the economical use of a single check rail! 105_140358_010000000.jpg As far as the Ffestiniog 3-way stub point goes, yes I have built one! The 2005 photos show this on a layout that no longer exists, although the crossing assembly does and will be incorporated into my "flat bottom" layout that's been discussed recently. The crossing assembly is straightforward to build, as was the switch (the photo shows it prior to having the tie-bars cut to fit an insulating sleeve over). The difficulty was in the operation ...

... There were multiple reasons that stone sleepers were fairly standard until the mid 1830's. 1. Due to the hang overs of the Napoleonic Wars, (which only finished in 1815), timber was still expensive. Especially the good stuff. Stone work was comparatively cheap. Though this would change by the mid to late 1830's. Also the engineering 'thoughts' behind the design. See number 3. 2. Till the development of pressure injected creosote treatment of wood in 1832, timber sleepers tended to rot a little faster than was economically feasible. Stone sleepers on a main line had a life expectancy of 10 years. Especially with the habit of burying the PW to the head of the rails. 3. The design of early Permanent Way was about building unyielding foundations, like a house. The rails used to break due to the original elliptical style of rail, (which limited the spacing of the stone sleepers which worked much like bridge abutments), as it took a while for the penny to drop that the track work needed to be resilient rather ...
